Answer:

The correct answer is that it involves human embryonic stem cells (ESC).

Explanation:

Stem cells are regenerative and differentiating cells which can develop into any type of cells even after they remain inactive for a long time. They are the first differentiation cells of embryo proper which are formed just after the fertilization.

The research on these Embryonic stem cell (ESC) is a reason for legal and ethical issues which led to the social controversy after the first successful culturing of human  ESCs in the laboratory in 1998 by James Thomson and John Gearhardt as "it destroys the embryos to obtain the pluripotent ESCs.

Thus, it involves human embryonic stem cells (ESC) is the correct answer.

It's controversial because the best source of stem cells is a human embryo (an aborted fetus).

daser333 [38]

Answer:

Blood cells

Explanation:

Hypocapnia refers to a situation whereby carbon dioxide is at a reduced level in the blood. This phenomenon is usually caused by deep/rapid breathing known as hyperventilation.

It signals a breakdown in the exchange of gases inside your blood cells where the stuff your body doesn’t want is swapped out for the stuff it desperately needs.

High concentrations of solutes such as sugar or salt results in plasmolysis of cells due to the onset of which phenomenon. Selec
malfutka [58]

Answer:

The correct answer will be option-B

Explanation:

Three types of solution are formed based on the concentration of the solute which are:

1. High solute concentration- Hypertonic solution

2. Low solute concentration- Hypotonic solution

3. Equal solute concentration- Isotonic solution

When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.

If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.

Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.

Why would a diverse community be more resistant to disease, predation, and invasion
Shtirlitz [24]

Answer and explanation;

-A diverse community would be more resistant to disease, predation, and invasion because it would be a bigger diversity of genes, which means that the chance of disease would be more likely to spread in a different area than in a diverse population.

-Diversity is expected to increase the resilience of ecosystems. A diverse community would be more resistant to disease because of simple biology. The more sources for possible resistance the better the heterogeneous pool will be at resisting disease.

-High diversity strengthens a community and prevents invasion of the introduced predator. After a gradual loss of native species, the introduced predator can escape control and the system collapses into a contrasting, invaded, low-diversity state.
