Answer:

C. Sexual reproduction produces genetically diverse offspring. Genetically diverse populations are more resilient to environmental disturbance and are less likely to go extinct.

Explanation:

Genetic diversity is the greatest advantage of sexual reproduction. Other than random mutations, asexual reproduction offers no genetic diversity. A population of clones that lack genetic diversity are at a much greater risk for population decline and extinction in a changing environment.

Select 3 true statements about Analogous Structures
Debora [2.8K]

Answer:

A. They have the same function

B. They have evolved independently

C. They indicate an evolutionary relationship

Explanation:

  • Analogous structures are structures with a different embryonic but have evolved to perform similar function.
  • <em><u>Analogous structures are a result of convergent evolution which is the independent evolution of similar features in species of different lineages or different embryonic origin.</u></em>
  • Examples of analogous structures include; wings in flying animals like bats, birds, and insects, and fins in animals like penguins and fish.

In humans, methylation of chromosomal DNA is a signal that often leads to
Ulleksa [173]

Answer:

The correct answer will be option-formation of heterochromatin

Explanation:

Methylation of DNA is the epigenetic mechanism which controls the expression of a gene by adding a methyl group to the cytosine bases in eukaryotic DNA.

The methylation of DNA converts the cytosine residues to the  5-methylcytosine catalysed by DNA methyltransferase enzyme. This results in the silencing of the gene and transcription get switched off.

Studies have shown that DNA methylation is involved in the formation and maintenance of the heterochromatin structure which is the condensed form of the chromatin in which transcription is switched off.

Thus, the formation of heterochromatin is the correct answer.
