Diffusion In Agar Cubes

zaineo2015 on

3cmx2.5cmx2.5cm cube         1cmx1cmx1cm               Cube

 

Hypothesis :   The Lesser volume there is , the more efficient diffusion can be. Meaning a smaller cube will undergo diffusion quicker and more thoroughly than a larger cube

 

Data Table :

 

 

1)In terms of maximizing diffusion, what was the most effective size cube that you tested?

1- in terms of maximizing diffusion , my group and I found the 1 cm cube to be the most efficient and effective .

2-Why was that size most effective at maximizing diffusion? What are the important factors that affect how materials diffuse into cells or tissues?

 

The 1 cm cube was found to be the mos effective since it had a lesser volume than the rest of the cubes. We found out the smaller the cube is ( in terms of its volume) the more efficient it would be at diffusion since there is less volume and space to cover meaning the whole process would be faster . You can notice our 1 cm cube to be more pink and have a deeper contrast of the 3 cubes.

 

3-If a large surface area is helpful to cells, why do cells not grow to be very large?

 

The surface area to the volume ration gets smaller as the cells gets larger . Thus , if the cell grows beyond a certain limit , not enough material would be able to cross the membrane fast enough to accommodate the increased cellular volume.

 

4-You have three cubes, A, B, and C. They have surface to volume ratios of 3:1, 5:2, and 4:1 respectively. Which one of these cubes is going to be the most effective at maximizing diffusion, how do you know this?

 

The cube that will be the most efficient at maximizing diffusion will be the cube that has a higher surface area to volume ratio of 4:1 because it has a higher surface area to volume ratio so it is more efficient. Having a higher surface area to volume ratio will ensure the inside of the cube will be the most effective at maximizing diffusion

 

5-  How does your body adapt surface area-to-volume ratios to help exchange gases?

 

Our bodies have adapted to have larger organs which are made up of small spheres which cover as much surface area as possible in order to more  efficiently exchange gases . Our body has a job of making sure a good surface area to volume area is established in areas where the gas exchange occurs. In order to accomplish this , large animals such as humans need special respiratory organs such as lungs for taking in oxygen and removing carbon dioxide.

 

6-  Why can’t certain cells, like bacteria, get to be the size of a small fish?

 

In order to maximize diffusion throughout cells , certain cells need to stay small for proper function, which means if a cell like bacteria was the size of a small fish , the surface area to volume ratio would be too small to ensure proposer and thorough diffusion throughout the cell

 

7-What are the advantages of large organisms being multicellular?

 

Multicellular organisms have many types of cells , while unicellular only have one cell. Multicellular organisms have specialized cells that engage in more complex physical and cognitive tasks than unicellular organisms .  Also , multicellular organisms have separate organ systems to perform special tasks . These systems , such as cardiovascular, digestive and respiratory systems perform life processes that are necesssary for survival .

What is hope ?

Hope is a fresh start at life

Hope is the sun as we journey towards it

Hope is a breath of fresh air

after being submerged Underwater

Hope helps navigate us through life’s murky waters

 

what is hope ?

It is  the thing that lifts us up

when we are down

hope provides us with wings to fly

when we can not fly on our own

hope is the compass of our dreams

when lost in the darkness

 

 

 

For my poetry pairing project, I chose Finding Hope by Pat. A Fleming. The poem illustrates the poet’s neat perspective on his life and how he found hope. The poet envisions himself not living his life to the fullest, being too scared to achieve what his potential enables him to do. In the beginning, the author reminisces his times of past with a tone of melancholy and regret, which further adds to the suspense of him finding hope in the end.He ends off with: “So the time has now come to conquer my fears And to stand up and face a new day. Let the hurts of my past wash away with my tears
And stop letting my life slip away. I found the ending to be very powerful and eye-opening because it showed me that no matter what life throws out you people still have the strength, resilience, and perseverance to come out on top.T he imagery and manipulation of language used make it easy for the reader to relate to the struggles of the poet and in turn, allow for better interpretation of the poem. For my image, i chose a picture of a ship out at sea, by itself. I believe the simple picture of a lone ship represents how people are without hope , and that is lost. Without hope, we humans are lost.

The Infinitesimal 

Some believe you need to be in a position of power to enact change, however, in most cases, it turns out to be the total opposite. Your actions speak volume and will continue to remain more powerful than you will ever be. So the question remains, do we have to appeal to the powers that be to enact change or can change be started from the bottom of the pyramid?. Gandalf’s quote reinforces Allison’s thesis on how change can be made by the small everyday deeds by everyday people. Howard mentions how walking through the rain is her infinitesimal deed to catapult the wheel of change, and this, in turn, goes hand in hand with what Gandalf is saying. To answer my question, yes change can begin from the grassroots of society. For instance, during the Vietnam war, there were a small group of people boycotting the war In the begging. As it grew costlier and deadlier more people were becoming aware, choosing the course of change and taking action. Another issue where our small contributions make a difference is the environment. Over the course of the past decade, people have become more aware of the devastating effects of climate change. Environmental awareness has spread throughout the world with simple infinitesimal changes that contribute to saving the planet. Overall, the entirety of the world’s social, environmental, and political movements not only prove Howard’s and Gandalf’s thesis but also strengthens it and proves it to be universal.

What is overpopulation? Surely, we now know what overpopulation means.Overpopulation is the condition of being populated with excessively large numbers, more numbers than our resources can sustain. The article I read provided very insightful information as to why we should worry about overpopulation, but above all what frightened me the most was the fact that If our population does not stop growing , we are at risk of famine , war , and poverty. According to the Malthusian theory of population , it states that human populations grow exponentially while food productions grow at an arithmetic rate. This scenario of arithmetic food growth with simultaneous geometric human population growth predicted a future when humans would have no resources to survive on.  To avoid such a catastrophe, Malthus urged controls on population growth. The article addresses issues such as carrying capacity and food security around the world. What got me hooked to this article was its message on quality of life versus quantity of life. The writer specifically urges us to change our ways or to suffer the consequences of our irresponsible choices along with the fact that the planet’s carrying capacity will soon reach its maximum at our rate of waste and consumption. Reading this article reminded me of Malthus’s book An essay on the principle of population , because  both literary pieces carry the same message regarding population sustainability. Reading this marvelous piece has got me to think on how I , personally can change my ways to improve our planet.

Roid Rage

 

Athletes have long been looking for ways to better themselves; whether it be by training more, eating better, or recovering more. In business and politics, shortcuts are encouraged by many and are applauded by the public; but when shortcuts are discussed in competitive sporting ,the debate tends to  get a little more heated. The use of steroids has long been public knowledge and it is not ground-breaking news to us anymore. anabolic steroids are made in laboratories and have the same chemical structure as the steroids found in the male sex hormone testosterone. The muscle-building (anabolic) and masculinizing (androgenic) effects of these drugs make them appealing to athletes and bodybuilders. So the question that bogs us all is, are they ethical ? To some the answer may simply be “No, they are not. They give athletes an unfair advantage” this does not seem to be the case for Raymmar Triado , the author of Is It Time To Say Yes To Steroids In Professional Sports? He puts forward a compelling argument in favor of their use by explaining that they are not like magic potions. Triado uses figurative language , irony , and even includes parallelism in his articles. His argument is that why do steroids need to be band in an era where the athletes are trying to better themselves in their respective fields of sport. Triado reveals that we all use things that make us feel better such as: coffee, Adderall , and cigarettes. The Author emphasizes the fact that if we can use prescriptions and legal drugs ( coffee ) to make ourselves feel and operate on a much higher level then athletes are not to be an exception. Steroids are and will remain to be a center of controversy and an endlessly debated topic. Whether It is ethical or not , that remains up to the user themselves.

   Trojan Horse

 

 

Baby steps

 

two, I begin to crawl,

Crawl away with joy.

They told me I would grow up to have it all

And be as mighty as Hector of troy.

Ten, I begin to believe life is filled with mystery,

I was told the world has many beautiful, bountiful, and breathtaking places.

I begin to think that life has no misery,

A thousand joyous ,but who knows what’s behind their faces .

Thirteen, I begin to see the true face of the life,

A life where people have mastered the art form of disguise

In a world lacking serenity, yet filled with strife.

Our lives are like paintings, there are more too it than what meets our eyes.

Sixteen, I realized life is like a trojan horse,

masked as beautiful , yet the source of  misfortune filled with displeasure.

As soon as the horse is let in , begins the remorse .

To my dear melancholy, we are alone together.

 

 

Baby Steps Composition

 

Life can be a long journey filled with ups and downs, for some it may have more ups than downs , and for others it may have more downs than ups .In the poem Baby Steps  by Zaine Osekrie , Zaine reveals insight to his life as he grows with age. Osekrie reveals how life is not as “they” have always told him , “they” are most likely his parents or society in general.  The poem is a narrative in which the poet is the speaker. Baby steps carries a tone of heavy sadness ,in which Osekrie shows through his choices of words and description of his perspective on life. The poem’s theme seems to exhibit a youth versus age theme, where the Poet’s perspective on life is constantly shifting as he grows older .Osekrie’s poem maintains an ABAB rhyme scheme with a variety of metaphors , similes , and such .

 

As he grows older he sees the world for what it really is , a sad world and not sugar-coated by “They”. The poem starts off with a positive tone regarding life and slowly beings its descent to a dire tone. Throughout the poem Osekrie makes two notable allusions to Greek mythology: “ and be mighty as hector of troy” In Greek Mythology , Hector was a Trojan prince and the greatest fighter for Troy in the Trojan war. His allusion to Hector of troy was meant to show the protection and care  parents provide their child at early stages of their lives by telling their children things to encourage them(child innocence). The second Reference refers to the Trojan Horse :” Sixteen , I realized life was like a trojan horse “ According to Greek mythology , after 10 years of the siege against Troy , the Greek built a giant wooden horse filled with supplies and presented it as a gift to the Trojans. The horse was a trap and contained a small army of Greeks who infiltrated the city of Troy via the horse. The Trojans were deceived with the beauty of the horse and it ultimately cost them the war .  Osekrie purposely alluded to and described life as a Trojan horse to emphasize on the theme of appearance versus reality , and the fact that there is so much more to life if you dig deeper.

 

Osekrie perspective on life can be regarded as pessimistic and may be sort of realistic  .The poet uses the simile of “our lives are like paintings , there are more too it than what meets our eyes “  to show the complexity behind people’s true feelings and intentions . In the eighth line “ A thousand joyous , but who knows what’s behind their faces”  the poet’s intention was to show the mask many people hide their emotions  behind. We live in such a desensitized world that it is difficult to tell fake from real emotions. Osekrie uses Synecdoche in his poem as well, in the ninth line he says “Thirteen, I begin to see the true face of the life” by saying that , Osekrie is revealing how he began to see what life truly is. The poem is ended with the line:” to my dear melancholy, we are alone together “ This is a paradox because it is contradictory given the fact that a person can not be alone and together with somebody at the same time. Osekrie addresses his sadness by revealing that he is not all alone , and infect accompanied by his cloud of sadness.

 

 

Overall, the poem is insightful and sheds light on the human condition along with society’s problems. It addresses how society has difficulties with expressing their feelings because they have become so desensitized as a result of all the conflicts that plague our world.  The poet also hints how he feels about the world in a subtle way.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Canada prepares for war

zaineo2015 on
  • 1)The Canadian Parliament didn’t choose to go to war in 1914. The country’s foreign affairs were guided in London. So when Britain’s ultimatum to Germany to withdraw its army from Belgium expired on 4 August 1914, the British Empire, including Canada, was at war, allied with Serbia, Russia, and France against the German and Austro-Hungarian empires. Meanwhile for WWII ,Britain’s declaration of war did not automatically commit Canada, as had been the case in 1914. But there was never serious doubt about Canada’s response: the government and people were united in support of Britain and France. After Parliament debated the matter, Canada declared war on Germany on 10 September. Prime Minister Mackenzie King promised that only volunteers would serve overseas.

 

  • 2)The demands of total war meant that the federal government became more involved in planning and controlling the economy. In April 1940, the Department of Munitions and Supply was created and industrialist C.D. Howe was put in charge. He was given the authority to do whatever it takes to gear up the economy and deal with wartime demands. He convinced businesses to manufacture goods they had never produced before such as bombers , army vehicles , and tanks. The British Commonwealth Air Training Plan (BCATP), was a massive, joint military aircrew training program created by the United Kingdom, Canada, Australia and New Zealand, during the Second World War

 

  • 3) “Canada was reluctant in joining the war because of their lack of a military and the fact that they recently came out of the great depression “

Parliament was in favor of going to war, although Minister of Justice , Ernest Lapointe spoke against conscription and how the liberal supporters in Quebec would be fuming if conscription were to be implemented . Even though Canada was not obligated to go to war when Britain did , they still did . They did so because of what Germany did to Poland and because they had to support Britain and France in the fight against evil. Despite war being given the green light , there are some who were opposed to it such as the leader of the co-operative commonwealth federation (CCF) , J.S Woodsworth. He argued in favor of Canada remaining neutral and the fact that violence does not solve anything .  The BCATP was a major contributor to the war effort. The BCATP trained more than 130 000 pilots, navigators, flight engineers, and ground crew. The total cost was more than $2.2 billion, of which Canada paid more than 70 percent which goes out to show how much Canada wanted to help out during the war
