The discovery of DNA is very vital to back up Darwin’s theory.
Darwin’s theory was that species change with time (very slowly). He also came up with the theory of principle common descent which includes the thought that modern organisms have been produced through evolution, every new organism comes from pre-existing organisms, that each species has descended from other species, and that all species have shared a common ancestor. That theory can be supported by DNA and fossil records by multiple pieces of evidence. With fossils, the lower layers of rock are older, scientists can determine the source of changes in an organism based on the layers in the rock. Evidence for this theory also lays in the science of embryology as now we can see that many animals and human embryos look very similar which proves that we are all distantly related to common ancestors. DNA is used in the confirmation of Darwin’s theory as, when it was examined, it allowed enough variation to be considered new generations, and with that information, evolution is now understood as a process of changes in the frequencies of stable variants.
This week in math 10 we learned about how to evaluate a notation function. First things first, we need to know the different parts of the function. You can see in the photo below that every part has a label and as this chapter is mostly vocabulary based, it’s important you know what someone could be referencing.
There are a couple different ways that you can show your function, the first one im showing you is called ‘Mapping Notation’. The first thing you need to do is determine the ‘parent function’ aka the simplest form of that type of function, meaning they are as close as they can get to the origin
Next, you ask yourself, what changes in the equation? Or, what type of transformations are taking place in the equation. Let’s take a look at the example down below.
^and as you have the function you can write it in a product of ordered pairs to graph, ex. 2 ~~> (2, 10)
The next type of function notation we learned is simply called ‘Function Notation’.
Function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation. o evaluate a function, substitute the input (the given number or expression) for the function’s variable. Replace the x with the number/expression. (Function notation is expressed very similarly to mapping notation.)
The last way we are showing is called ‘Equation’. the main part of Equation is that they aren’t names/ labeled so the only was to clearly showcase it is by writing it down visually. also keep in mind that saying ‘Find f (2) when f (x) = 3x, is the same as saying, “Find y when x = 2, for y = 3x.”
voici mon ASMR aka mon SI LO ÉCOUTAIT chose! UwU !! j’espère que tu les adores! 🤠 🤠 🤠 🤠 🤠 🤠 🤠 🤠 🤠 aussi smash le subscribe button et n’oublie pas de thumbs up le vidéo! okay au revoir
I found my egg cup recipe on dinneratthezoo.com and I liked the simplicity of having a good and decently healthy breakfast that I could serve my brothers and my mom who enjoyed it. the recipe was easily substitutable with exchanging the bacon for vegetables as it didn’t alter the end result. It was time efficient and you can add more eggs and veggies to serve more people without exact measurements. Cooking went smoothly and I will definitely be making this again.
I chose to plan a trip to Puerto Vallarta, Mexico because it is very pretty and sunny. It is a fun place to experience new cultures and try new activities. I planned to go July 11th, and stay three nights. I will spend a lot of time at the beach, as Mexico beaches have warm water and sun!
I depart at 6:00AM on July 11th from Vancouver and arrive at 2:55PM on the same day in Puerto Vallarta, Mexico.
on June 12th, I plan to go swimming with the dolphins at 12PM
On June 13th I plan to go to a Mexican market at 11AM to go shopping for souvenirs
The rest of the time I plan on being at the beach or in the hotel lounge as this is a short trip and I don’t want to over book myself with activities in my short amount of time here.
The hotel I’m staying at is called the Samba Vallarta All Inclusive
To go from place to place I will be taking taxis / cabs.
The room is $328 /night
The food and drinks are all included so the price of the hotel room per night covers the price of meals and snacks.
Flight total = $683.31
Hotel total (food included) = $984
Activities total = $228.52
other expenses (cab fare) = $100
TOTAL = $1995.83
How I plan to save to save for this trip is to save $500 every year for 4 years.
