Diffusion In Agar Cubes

By
  1. in terms of maximizing diffusion, what was the most effective size cube of you tested? the most effective size cube is 1 cm cubes of maximizing diffusion.
  2. why was that size most effective at maximizing diffusion? what arex` important factors that affect how materials diffuse into cells or tissues? The 1cm cube was the most effective due to it having a smaller surface area than the other cubes, this makes it easier to cover the entire thing. Important factors that affect diffusion in cells or tissues are temperature, material, size and polarity.
  3. if a large surface area is helpful to cells, why do cells not grow to be very large? Surface area affects the volume and if an object has a high volume it will take a greater amount of time to diffuse even though it may have a lot of surface area. This is why cells do not grow very large.
  4. You have three cubes, A, B, and C. they have surfaced to volume ratios of 3:1, 6:2, and 7:3 respectively. Which of these cubes is going to be the most effective at maximizing diffusion, how do you know this? The 7:3 ratio cube will be the most effective at maximizing diffusion because of the balance of surface area to volume. It will have the most effective diffusion out of the three cubes.
  5. How does your body adapt to surface area-to-volume ratios to help exchange gasses? In our body have adapted in order to use large surface area organs that help exchange gases better
  6. Why can’t certain cells, like bacteria, get to be the size of a small fish? Cells like bacteria cannot get to be the size of a small fish because they need to divide in order to keep a good surface area to volume ratio. Additionally, bacteria depend on their organelles for survival whereas larger, multicellular organisms have specialized cells which they can depend on.

 

Ethic of Care

By
  1. What would be needed to create it?    we need to create people stop throwing garbage on the road
  2. What would we have to believe about the environment? How should we see it? we should believe that the environment is getting worst because we throw garbage on the road and it stuck into the water tap and water ut can’t go down
  3. How would we act? – give scenarios. when we have garbages on my hand and I don’t throw it on a road but I will bring it back and throw it in the bin.
  4. What would be different about the world if everyone adopted this ethic of care towards the environment? Benefits and drawbacks? it is different if peoples stop throw garbage and roads will not be dirty it is will be benefits for us and for animals that don’t have to eat plastic
  5. Should we adopt an ethic of care towards the environment? yes we should take care of the environment by  stop throw garbage on roads and start pick it up

Blog log one- business

here is the link to the article 

In this article, I interested in this topic about why the company like Amazon will go bankrupt. The Amazon company makes the profit about $3 billion per year but the CEO of Amazon said that the company will go bankrupt. In this article, I love the way how the imagery explanation that the company will not grow that much. The connection that I make is when I have my own business in the future, so  I have an experience that how to prevent my company will not go bankrupt y, and it has to be constantly. It is a fiction story because it doesn’t exist into the Amazon company that it will go bankrupt.
