How might a change of one amino acid at a site, distant from the active site of an enzyme, alter the substrate specificity of an

enzyme? by changing the optimum ph for the enzyme by changing the stability of the enzyme by changing the binding site for a noncompetitive inhibitor by changing the three-dimensional conformation of the enzyme?

<span>The correct answer is: by changing the three-dimensional conformation of the enzyme.</span>
 Enzymes like all the other proteins are shaped by interactions between their amino acids and when those interactions change, the 3D structure of the enzyme changes (tertiary structure). A change in shape will change the shape of the active site and the substrate cannot bind.

What is the relationship between cell division and growth?
dimulka [17.4K]

Answer:

The relationship between cell division and cell growth is that cell division needs to occur for the cells to divide and grow individually.

Explanation:

cell division refers to the process by which the mother cells divides into two daughter cells and cell growth refers to the process by which the size of the cell increases as it grows. They are two different but important and interlinked processes in the cell cycle. They depend on each other as failure in one will lead to failure in the other process too. The cell needs to grow proper in order to divide and create more cells.

How does dispersal help different species? dispersal helps different species to increase their range of places, thereby helping
icang [17]

Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.

<h3>What is dispersal?</h3>
  • Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
  • Dispersal can be active (move by oneself) or passive (require dispersers).
  • Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
  • This depends upon the effectiveness of the seed dispersers.
  • Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
  • Dispersal of seeds is very important for the survival of plant species.
  • If the plants of same type grow too closely, they have to compete with each other for light, water and nutrients from the soil.
  • Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.

Evidence for coordinated stasis is found in ____.
KonstantinChe [14]

The correct answer is option (A) the fossil record.

Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.

Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
