Some conditions that are possible reasons for declining genetic diversity of a species;

▪︎loss of habitat

▪︎inbreeding

Explanation:

Loss of habitat will definitely reduce diversity because it reduces the population size from increased competition for reduced resources. Some subspecies may be completely eliminated when their niche is completely lost.

Inbreeding also reduces diversity because it results in the expression of recessive genes in a population that are mostly disadvantageous. High inbreeding rates will result in most individuals not reaching maturity to pass down their genes to the next generations.

How can a molecule that contains an atom of phosphorus be made radioactive using an unstable isotope?
AVprozaik [17]

Answer:

A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule

Explanation:

Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.

However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.

This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.

Summarize the nature versus nurture debate, and explain how contemporary theorists view this debate.
Klio2033 [76]

One of the oldest arguments in the history of psychology is the Nature vs Nurture debate. Each of these sides have good points that it's really hard to decide whether a person's development is predisposed in his DNA, or a majority of it is influenced by this life experiences and his environment.
