Answer:
As we know enzymes are specific for different reactions and The conditions required by an enzyme to function are also specific. An enzyme which works in a basic environment will not be able to function in a acidic environment.
If the pH for a reaction is increased from 2 to 11 then this change will change the active site of the enzymes. As a result, the substrate will not be able to fit into the enzyme and hence the enzyme will not catalyze the reaction.
<h2>
Chi-Squared test.</h2>
Explanation:
The two genes are linked and are assorting together, leading to a ratio of phenotypes in the offspring that deviates significantly from 1:1:1:1.
Chi-squared test is a standard statistical study that is used to study the distribution of certain gene properties within a given population.
Chi-squared analysis help us to see and prove the degree of deviation of an observed phenomena from a theoretical assumption.
Answer:
B. They have a single small nucleus.
Explanation:
The presence of large nucleus is a characteristic feature of cells that frequently undergo cell division. Cancer cells are characterized by uncontrolled continuous cell division even when the new cells are not required by the body.
This leads to the formation of benign or metastatic tumors. To undergo continuous cell division, the cancer cells have a large nucleus. The nucleus of the cancer cells is mostly hyperchromatic and distinct due to higher nuclear to cytoplasmic ratio. It allows these cells to exhibit the uncontrolled cell division.
It is called inter specific competition
Answer:
true, i think! im sorry if im wrong
