Suppose that in humans the ability to roll the tongue (R) is dominant to being unable to roll it (r), and having freckles (F) is

tatuchka [14]

Answer:

1/4

Explanation:

A heterozygous woman for both traits (RrFf) marries with a man with no freckles (ff) who can't roll his tongue (rr).

The cross is: RrFf X rrff.

The woman can produce the gametes RF, Rf, rF and rf

The man can only produce rf gametes.

The possible offspring that can arise from the combination of those gametes is:

1/4 RrFf Freckled, tongue-rolling
1/4 Rrff Freckled, unable to roll tongue
1/4 rrFf Not freckled, tongue-rolling
1/4 rrff Not freckled, unable to roll tongue

based on what learned in bio202, arrange the following five events in an order that explains the mass flow of materials in the p

svp [43]

The correct order of the following events on the mass flow of materials in the phloem is:

Leaf cells produce sugar by photosynthesis.
Solutes are actively transported into sieve tubes.
Water diffuses into the sieve tubes.
Sugar moves down the stem.

Correct answer: letter C.

This is because the mass flow of materials in the phloem must pass through all these processes in a consecutive and orderly manner, from the cell to the stem, in order to allow nutrients and other vital materials to reach from the plant roots to the leaves and fruits.

<h3>How is this transport of nutrients and other vital materials achieved?</h3>

This is accomplished by the transport of solutes through the phloem's network of channels, which contain fluids, mineral salts, vitamins and other nutrients essential to plant health. Mass flow also helps distribute oxygen and carbon dioxide to all parts of the plant. These materials are necessary for plant respiration and growth.
