Answer:
The crust and outer part of the mantle.
Explanation:
The crust and outer part of the mantle are the two top-most layers of Earth. The lithosphere is comprised of these two. Here's a picture for an example.
With the ocean providing over half the oxygen we breathe and being a major source of food for the world’s population, there is a critical need for action and we all have the ability to make change.
Each year, at least eight million tonnes of plastics flow into the ocean — which is equivalent to dumping the contents of one garbage truck into the ocean every minute. If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050.
It’s sad to look at this picture and NOT look at how hurt sea animals are being hurt, how this WILL affect us in the near future, maybe even affecting us right now and we are too blind to notice. It’s painful to think of these things because sooo much is being lost. I hope people can open there eyes and realize the damage they are causing.
Answer:
50 atoms have decayed during that time
Explanation:
The radioactive decay is represented as

Where N is the amount of radioactive element after a certain time period
N0 is the amount of radioactive element during the initial time period
X is the half life of the radioactive element
Substituting the given values in above equation, we get:
atoms
So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.
Hence, atoms of carbon-14 that decay during 5700 years are 100-50 - 50
Answer:
The answer is below
Explanation:
The theory of color vision best that best explains this deficiency is called TRICHROMATIC COLOR THEORY. It was originally proposed by Thomas Young and later refined by Hermann von Helmholtz.
Here, Yasser’s color-blindness is associated with deficiencies in various cones. The most probable are red and green cones because of their high chance in men than women.
The theory of color vision best explains why he might see an afterimage is known as OPPONENT - PROCESS THEORY. It was originally proposed by Ewald Hering.
This is based on the principle that supposing Yasser, stared at a red image for a while and then stared at a blank white page, he would likely see an imprint of the image, but in green.
