Answer:

In a hypotonic solution, the solute concentration is lower than inside the cell. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies

Hypotonic solutions have lower solute concentrations than cells. If water keeps entering the cell, it can strain the membrane until the cell bursts and dies. Therefore, option (A) is correct.

In comparison to another solution, a hypotonic solution will have a lower solute concentration because of its composition. Without another solution to compare it to, it is impossible to determine whether a solution is hypotonic, isotonic, or hypertonic. A solution is said to be hypotonic when it has a relatively low concentration of solutes in comparison to another solution.

As a consequence of this, the solute concentration is lower in a hypotonic solution than it is inside of the cell. If the water continues to enter the cell, it has the potential to stretch the cell membrane to the point where the cell lyses and dies as a result of the rupture.

Explanation:

A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sámi word тӯндар meaning "uplands", "treeless mountain tract".

Answer:

Mitosis

Explanation:

Meiosis is the splitting of sex cells which happens during reproduction. Mitosis is the splitting of body cells in order to make more body cells. Mitosis is how your body grows, therefore it occurs more frequently because the body is not constantly reproducing.

In the human body, mitosis occurs more frequently than meiosis. Mitosis is a type of cell division that happens in somatic cells, which are non-reproductive cells.

It is responsible for growth, repair, and maintenance of tissues in the body. On the other hand, meiosis occurs only in reproductive cells, such as sperm and egg cells, and is involved in the formation of gametes for sexual reproduction.

Here is a step-by-step explanation:

1. Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells. It consists of several stages: interphase, prophase, metaphase, anaphase, and telophase. During interphase, the cell grows, replicates its DNA, and prepares for division.

Then, in prophase, the DNA condenses into chromosomes, and the nuclear membrane breaks down. In metaphase, the chromosomes align in the middle of the cell. Next, in anaphase, the chromosomes separate and move to opposite ends of the cell. Finally, in telophase, two nuclei form, and the cell divides into two daughter cells.

2. Meiosis: Meiosis is a specialized type of cell division that produces gametes with half the number of chromosomes as the parent cell. It involves two rounds of division, resulting in the formation of four haploid cells. Meiosis consists of two main stages: meiosis I and meiosis II.

In meiosis I, the homologous chromosomes pair up, exchange genetic material in a process called crossing over, and then separate, reducing the chromosome number by half. Meiosis II is similar to mitosis, as the sister chromatids separate and move to opposite ends of the cell. The end result is the formation of four genetically unique haploid cells.

Although both mitosis and meiosis are essential for different purposes, mitosis occurs more frequently in the body because it is involved in the growth, repair, and maintenance of tissues.

Ecological balance is a term used to describe the equilibrium between living organisms such as human being, plants, and animals as well as their environment. ... Therefore, this balance is very important because it ensures survival, existence and stability of the environment

Explanation:

If one species is lost the entire ecosystem can stop working. ... If something happens in an ecosystem, it can shift from a state of balance to a state of imbalance. Ecological imbalance is when a natural or human-caused disturbance disrupts the natural balance of an ecosystem.

Answer:

Introduction of Non-native species would be the answer. ( B )

Explanation:

Now let's break it down.

A. Competition due to overpopulation

Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.

B. Introduction of Non- native species.

So what does it mean by Non-native species?

It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.

C. Catastrophic Events

Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.

D. Disease

This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.

So, the Answer would be B.

Among the given options, the one that is a natural cause of extinction would be:

b). Introduction of non-native species.

'Non-native species' are described as the species that are introduced to an ecosystem different from its native habitat.

These species are severe threat to the existing ecosystem of the new habitat including plants, animals, aquatic life, etc. where they've been shifted.

Thus, it is not a natural cause as these species are not naturally introduced but the humans introduce them.

They turn so dominating to get their food and other things that it lead not only harmful but also lead to the extinction of the native species.

Hence, option b is the correct answer.
