Answer:
A
Lipids are water soluble fatty acids that are the primary component of cell walls; they regulate water uptake by the cell because they form carbon chains.
B
Lipids are water insoluble fatty acids and the are the primary component of cell walls; they protect the cell and help maintain its shape because they form carbon rings.
C
Carbohydrates like cellulose and chitin are the primary component of cell walls; they repel and prevent excess uptake of water because they form rigid linear carbon chains.
D
Carbohydrates like cellulose and chitin are the primary component of cell walls; they protect the cell and help maintain its shape because they form chains of rigid carbon rings.
Answer:
B: It occurs only in cells in the reproductive structures of organisms.
Explanation:
Out of the following choices, fossil fuels is the largest reservoir of carbon in the world. A couple of other reservoirs of carbon are dissolved in the ocean and in plants.
<span><span>a. </span>Reproducing</span>
f. obtaining
energy
d.
maintaining structure
Why do these
three illustrate the great challenge for every species.
<span><span>
1. </span>Reproduction, is as vital for an entire race to survive. It prolongs
their generation onwards and offspring to the next centuries to pass by.</span>
<span><span>
2. </span>Obtaining energy. In both humans and animals, even plants is a
challenge because these creatures need to work in order to obtain these need
resource from food –preys.</span>
<span><span>
3. </span><span>Maintaining structure. For the living organisms to still exist they
need to keep themselves intact. Combating diseases and having nutrition. This is
a by-product of having energy. </span></span>
Capillaries are the end structures in the artery system that bring oxygenated blood from your lungs to the rest of your body.
