Answer:
An adaptation.
it's trying to stay safe from predators in the same way it feeds.
The event order should be:
1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume
Answer:
<u>50%</u>
Explanation:
<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.
Answer: if the trees and lakes were destroyed there would be no homes for most animals and they might become exctinct. Trees provide us paper and oxygen, store carbon, stabilise the soil and give life to the world's wildlife. They also provide us with the materials for tools and shelter.
Explanation:
The mixture of gases that is thought to have made up Earth's early atmosphere is hydrogen, water vapor, ammonia, methane, carbon dioxide<span>. This is previous to life so oxygen was not present because it was produced when green plants existed to produce oxgygen through photosynthesis. Ozone was absen and so the uv radiation entered the atmosphere and it is thought that (along with electrical discharges) could vave contributed to the formation of the first organic molecules from the given mixture of inorganic gases.</span>
