C. Specialized cells may lose the ability to reproduce.
Novay_Z [31]3 years ago
4 0

Answer:

The correct answer will be option-C.

Explanation:

Specialization is the fundamental property of the multicellular organism which is related to the complexity of the organism. The specialization can be exhibited by unicellular organisms like bacteria to form biofilms.

This specialization in the multicellular organism becomes permanent through the process of differentiation. Cells attain a particular function depending on the environment they are present as well as the signals from the adjacent cells.  The cells work in cooperation and lose the ability to divide and reproduce after they get differentiated to perform a function.

Thus, Option-C is the correct answer.

What is an effect of genetic drift on a gene pool?
Ahat [919]

Genetic drift happens by chance and can make an allele disappear completely from a gene pool, even if it was a desirable trait that should have been passed down to offspring. The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population.

SCORPION-xisa [38]
<h2>b) option is correct </h2>

Explanation:

  • Some bacterial toxins cause disease by  altering the activity of G protein, cholera toxin is one of them
  • Cholera toxin catalyse ADP ribosylation of Gs and blocks GTPase activity thus Gs GTP become permanently active
  • Constitutive activation of Gs protein continuously induce adenylyl cyclase, cytosolic cAMP level rises that leads to activation of protein kinase A (pKA)
  • Activated pKA catalyse phosphorylation of two transmembrane proteins of intestinal epithelial cells:
  • CFTR cause excessive outflow of Cl- ion and Na+ H+ exchange cause efflux of Na+ ion, both enters in gut and form Na+ Cl-
  • Na+Cl- leads to outflow of water from the gut, resulting in diarrhea and dehydration and this condition may cause death of organisms due to loss of water and ions

What is the process in the cell can be disturbed by the destruction of the mitochondria?
Troyanec [42]

Answer:

The correct answer is - C. oxidation of substances organic.

Explanation:

The major function of the mitochondria is to perform cellular respiration and produce energy in the form of ATP by oxidating organic molecules. All the process requires energy to be processed, however, the main and primary process that would disturb if by the destruction of the mitochondria occur which is the oxidation of glucose to convert it to pyruvic acid to generate energy.

The Krebs cycle that takes place in mitochondria and performs oxidation of organic molecules will also be disturbed and there will be no energy for any process.
