Nucleotides makes up each individual strand of DNA
Answer:
The correct answer will be- red blood cells (RBC)
Explanation:
Malaria has proved endemic to the human species as it has killed the humans in large numbers and it has acted as one of the strongest selective force.
The malaria disease has caused the mutation in the genes in the red blood cells which carries the oxygen to different organs of the body. The mutation in the genes causes the circular shape of red blood cell to sickle-shaped cells which carry less oxygen to the organs.
The change in the shape of red blood cell provides resistance against malaria disease but it becomes a problem where malaria is not a problem.
Thus, red blood cells (RBC) is the correct answer.
Answer:
Inhibitors of cyclin-dependent kinases might play a role in regulating the concentration of cyclin in the cell cycle.
Explanation:
The presence of inhibitors of cyclin-dependent kinases has a great importance because it controls the concentration of cyclin that is necessary for the cell cycle. If inhibitors of cyclin-dependent kinases is absent , the amount of cyclin increases in the cell formation and cause a great damage to the cell cycle and the cell which is produced is abnormal or other irregularities.
The appropriate answer is c. a tertiary consumers. Tertiary consumers are usually carnivores that eat other carnivores. The grass in the food chain is the primary producer. Primary producers are plants who get their energy from the sun. The grasshoppers are primary consumers or herbivores. The frogs are secondary consumers and they are also carnivores. A food chain shows how energy is passed on in an ecosystem.
Answer:
Fossils can be described as the dead remains of plants and animals which are used to study evolutionary histories of organisms. The most common type of rocks on which imprints of dead plants and animals will form are the sedimentary rocks. The fossils found on the sedimentary rocks can also be used to date the sedimentary rocks and study how old the rock or the imprints on it are.
