Which substance on the plasma membrane helps identify chemical signals from outside the cell?
cluponka [151]

Answer:

<em><u>The correct option is A) carbohydrate chain</u></em>

Explanation:

The carbohydrate chain present in the cell membrane helps determine the characteristics of the cell and it also helps to identify the chemical signals from outside the cell. Hence, option A is correct.

Other options, like option B, is not correct because the function of the cholesterol in the cell membrane is to prevent the fatty acids from sticking together. Option D is not correct because transport proteins help some molecules to move inside the cell.

2. How has genetics, combined with<br> paleontology, added to our<br> understanding of evolution?
motikmotik

Answer:

To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.

Explanation:

  • Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
  • The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
  • When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
  • By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
  • By using these techniques, biologist have found that <em>homo sapiens</em>  are 99% have their similarities with chimpanzee
  • Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
