Answer:

The correct answer is d.  increases at a slower rate.

Explanation:

As the volume of a cell increases a cell grows bigger but unfortunately the surface area does do not increase as faster as the volume, therefore, the relative surface area amount which is available to pass the molecule across plasma membrane per unit volume decreases.

Therefore as the cell increase in size the surface area to volume ratio decreases. So if a cell grows more than its limit it will get difficult to move molecule fastly across its membrane. Therefore the correct answer is d.

How is a trophic cascade (top down regulation) different from the traditional trophic pyramid (bottom up regulation)?
Sidana [21]

Top-down effects imply control through predation, including fishery, while

bottom-up effects imply control through food abundance, often thought to be driven by climate or nutrient load.

<h3>What is Top down regulation ?</h3>

The top-down effect refers to a higher trophic level influences the community structure of a lower trophic level through predation.

<h3>What is Bottom up regulation ?</h3>

The bottom-up effect means that a lower trophic level in the biological network affects the community structure of higher trophic levels by means of resource restriction

Fruit color in a particular plant is controlled by a set of three quantitative trait loci (i.e., QTLs or polygenes), that work i
tankabanditka [31]

Answer:

1/8

Explanation:

Given that the trihybrid parents have AaBbCc genotype for fruit color. The trait is a quantitative trait i.e. each dominant allele will have an additive effect on it. In this case, AaBbCc and AABBCC will not produce same fruit color because AaBbCc has only three loci contributing to the color while in AABBCC all the six loci are contributing to the color. For an offspring to be exactly similar to the AaBbCc parents it should have the same genotype of AaBbCc.

The probability of Aa to come from a cross between Aa and Aa is 2/4 or 1/2

The probability of Bb to come from a cross between Bb and Bb is 2/4 or 1/2

The probability of Cc to come from a cross between Cc and Cc is 2/4 or 1/2

So the collective probability of AaBbCc offspring from a cross between AaBbCc and AaBbCc parents would be=

1/2 * 1/2 * 1/2 = 1/8

Hence, assuming no effects of the environment, 1/8 of the offspring will have the same fruit color phenotype as the trihybrid parent.
