How are substances carried to cells in a tissue and how are wastes removed

Answer:

Both processes rely on blood circulating throughout the body.

Blood is oxygenated in the lungs. The blood carries the oxygen to tissues, where the oxygen is released so that tissues can use it for cellular respiration. At the same time, carbon dioxide waste produced by the tissues enters the blood and is carried back to the lungs to be exhaled. At the same time, fresh oxygen enters the blood and the cycle begins again.

This is a very general explanation but I can explain in more detail if needed.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R

Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

$\frac{3}{4}*\frac{1}{4}=\frac{3}{16}$

Therefore, the answer is A. 3/16
