Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
A lipid that has 3 long chains of fatty acids covalently attached or bonded to the glycerol backbone would form a single triglyceride molecule.
Answer:
We have to evolve or we will just slowly die off.
The first statement matces with the last option - autosome
The second one goes with chromosome theory
Then, third is diploid
The next - haploid
Sixth - <span>linkage
Then </span>x chromosome and y <span>chromosome
Hope you still need the answer because this one is really helpful.

If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around. They are not strong enough to hold organs or hold its shape.
