Which of the following is a correct statement about sugar movemetn in phloem?

Biology
1 answer:
Simora [160]4 years ago
7 0

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.

Viruses evolve rapidly in part because of the error-prone nature of their replication enzymes, but not all viruses evolve at the
Ierofanga [76]

Answer:

retroviruses

segmented viruses

Explanation:

A retrovirus is a type of RNA virus that inserts a copy of its genome into the DNA of a host cell that it invades resulting in changing the original genome of that cell. There are about three examples of retroviruses, they are

* HIV

* Human T-lymphotropic virus type 1 (HTLV-1)

* Human T-lymphotropic virus type 2 (HTLV-II)

It should be understood that there is a difference between virus and retrovirus. This is that a retrovirus inserts its genome into the host's genome unlike the virus.

Segmented viruses are viruses that package all of their genome segments into a single particle.

In this case, these viruses have high rate rate of genetic mutation and adaptation.
