How can humans reduce the amount of endangered and extinct species?
Andrews [41]
There are many ways humans can reduce the amount of endangered and extinct species. However, I would say by reducing pollution and logging/mining. Nearly 318 species have become extinct due to pollution. The reduction of carbon emissions would be a good way to curb the amount of pollution produced by humans.

quizlet i]n the heart, valves are located in the heart, valves are located just between the ventricles and the arteries. just be
ser-zykov [4K]

In the heart, the valves are located between atria and ventricles and between ventricles and arteries (option D).

<h3>What are valves in the heart?</h3>

Valves are membranous partitions which permit the passage of the contents of a vessel or cavity in one direction, but stop or control the flow in the opposite direction.

Valves in the heart enforce a one-way blood flow through the heart and separate atria from ventricles, and ventricles from the large arteries that leave them.

The four valves in the heart and their location is as follows:

  1. tricuspid valve: located between the right atrium and the right ventricle
  2. pulmonary valve: located between the right ventricle and the pulmonary artery
  3. mitral valve: located between the left atrium and the left ventricle
  4. aortic valve: located between the left ventricle and the aorta.

The valves between the atria and ventricles are called atrioventricular valves or cuspid valves while those at the bases of the large vessels leaving the ventricles are called semilunar valves.

Therefore, it can be said that the valves of the heart are located between atria and ventricles and between ventricles and arteries.

If there is no lactose present, how does bacteria respond? The gene for beta-galactosidase turns on. The gene for beta-galactosi
mojhsa [17]

Answer:

The gene for beta-galactosidase turns off.

Explanation:

The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.

Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.

If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).

How one lives is so far distant from how one ought to live, that he who neglects what is done for what ought to be done, sooner
Genrish500 [490]

Answer:

To increase the preservation of an element, it should go through all the stages as it should, which could promptly take it to its ruin phase.

This must be analyzed from the theoretical point of view, it will be worthwhile for the human to go so fast through the phases of his life, shortening the chances of subsistence or we must burn all stages in due time.
