Which of the following statements concerning complex multicellular organisms is true?- Plants and animals use bulk transport sys

tems to move gases and nutrients, but fungi and algae do not.-Bulk transport systems require specialized organs like a heart to pump nutrients and dissolved gases deep into tissues that are not in contact with the external environment.- Bulk transport systems move substances faster than simple diffusion.

<u>Answer:</u>

<em>The true statement concerning complex multi-cellular organism is Bulk transport systems move substances faster than simple diffusion.</em>

<u>Explanation:</u>

<em>Bulk transport</em> is the mechanism that is used by the cells to transport the large quantity of small and tiny molecules and particles. Bulk transport works on the <em>mechanism of pressure gradient and single diffusion</em> is based on the concentration gradient.

The<em> transportation on single diffusion</em> is due to random motion of molecules but in bulk transport the solute and water is moved <em>together and in a faster pace. </em>

I’m having trouble understanding this can someone plz explain?
Leni [432]

Answer:

look at the pictures

Explanation:

1. If we cross the parental generation which is RR x rr, the probability of the F1 generation to get  rough coat is 100% and they will be a carrier of the recessive trait smooth coat.

Since the phenotypic ratio is 100% heterozygous Rr, in crossing the F1 to get the F2, we will use the genotype Rr. To get the F2, use the cross  Rr x Rr.

The phenotypic ration for F2 is 3:1. There is 75% to get rough coat and 25% smooth. The answer is based on the result on the Punnett square. On the other hand, the genotypic ratio is 1:2:1. There is 25% probability to get RR genotype, 50% Rr, and 25% rr.

2. Since the two parental mice got 6 albino offspring and 5 brown mice offspring, it is approximately 50%. it takes a parental mice who is Brown that is carrying an albino trait crossed with an albino to get offspring with almost the same number. Therefore, the genotype of the brown mice is Aa.
