<h3><u>The Food webs are preferred over food chains for representing the flow of energy in an ecosystem for the following reasons: </u></h3>
  • The food webs are higher in complexity when compared to food chains and also, in food web, more than one primary producers is present which increases the 'flow of energy' in the ecosystem.
  • Food web represents the real life better than the food chains do.
  • Food web shows many different paths through which the organisms can be connected.

Illusion [34]

Answer:

Stabilizing selection

Explanation:

Stabilizing selection is the most common form of natural selection that is not easy to notice in a population as the change is less drastic.  It occurs when average or intermediate phenotypes of a trait in a population are favored, while the extreme phenotypes of that trait are not favored by the forces of natural selection. Over time, intermediate or non-extreme traits become more common in the population, while extreme traits become less common.

Vesna [10]

Answer: Option B) Nuclei house the DNA, which is the blueprint for proteins. Cell types I, II, and III can synthesize proteins.

Explanation:

All the genetic information that determines the traits expressed in an organism are loaded up within the DNA sequence. Hence, several genes that codes functional proteins are derived from the DNA, making DNA a blueprint for protein synthesis.

Thus, Cell types I, II, and III with DNA can synthesize proteins.

A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR).
igomit [66]
So I don’t see answer choices here, but your answer is 50% of the offspring will be homozygous dominant with RR, and 100% of them will carry a homozygous dominant gene of Rr

If you take the two sets and put them into a punnett square, it would look like this (image attached):

When the two sets of alleles are crossed, you would end up with half of your pairs being fully dominant (RR), and the other half being dominant while containing a recessive gene (Rr). Since there’s only one recessive gene in these pairs, it gets overridden and the pair itself is dominant.

So your answer is 50% will be homozygous dominant with RR!
