The theory of evolution<span> by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.</span>
Answer: plateaus
Explanation: there not canyons so you can cross that off and its not the dunes nor the deltas so if you look at the picture you can tell it is the plateaus
Answer:
Parasites are organisms that infect the body of another living being and live off their hosts to survive. While some parasites create no symptoms in their hosts, others can cause severe illness. Parasitic infections occur when parasites grow, reproduce, or invade organ systems that make their hosts ill.
Answer:
Thought the process of discussion and ossmossis as due to gaseous exchange
Explanation:
With the aid of thin layers and large surface area animal are able to transport material thought the blood due to diffusion and osmosis In order to transport different materials from a every of high concentration to a low concentration until material is equally distributed throughout the body
The fluid-mosaic model describes the plasma membrane of
animal cells. The plasma membrane that surrounds these cells has two
layers (a bilayer) of phospholipids (fats with phosphorous
attached), which at body temperature are like vegetable oil (fluid).
And the structure of the plasma membrane supports the old saying, “Oil
and water don’t mix.”
Each phospholipid molecule has a head that is attracted to water (hydrophilic: hydro = water; philic = loving) and a tail that repels water (hydrophobic: hydro = water; phobic
= fearing). Both layers of the plasma membrane have the hydrophilic
heads pointing toward the outside; the hydrophobic tails form the inside
of the bilayer.
Because cells reside in a watery solution (extracellular
fluid), and they contain a watery solution inside of them (cytoplasm),
the plasma membrane forms a circle around each cell so that the
water-loving heads are in contact with the fluid, and the water-fearing
tails are protected on the inside.
