The scenario that is best described here is a change in the region's BIODIVERSITY. This measure (biodiversity) indicates the genetic/phenotypic variability found in a region.

Biodiversity refers to the genetic and phenotypic variability of the organisms found in a particular geographic region or the variety of life on the Earth's planet.

Biodiversity can be used to indicate the amount of variation at different levels (i.e., genetic, species, and ecosystem levels).

The different types of animals, plants and microorganisms that live in a forest represent an example of biodiversity.

Reproduction in prokaryotes occurs primarily through the process known as Binary Fission.

Answer:

MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.

A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.

The checkpoints during mitosis are:

The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.

That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.

Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

The statement 'C. parvum is a single-celled, eukaryotic parasite that infects human cells in the digestive system and causes illness' is TRUE. This parasite causes diarrhea.

Cryptosporidium parvum (C. parvum) is a single-cell protozoan that may cause severe self-limited diarrhea in immunocompetent individuals.

Cryptosporidium parvum develops its complete life cycle in the human intestines (also it can be found in animal intestines).

This species (Cryptosporidium parvum) is one of the six (6) known species of Cryptosporidium.

The virus is a type of microorganism that contains DNA (Deoxyribonucleic acid) and surrounded by a protein coat.

There are different types of viruses which include:

The parts of a virus include:

The viral envelope is the external part of the virus, which is made up of proteins and lipids, and is capable of protecting the virus from harm.

Also the cell wall of the eukaryotic cell wall also protects these organisms from external harm.

Explanation:

Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

Answer:

Meiosis

Explanation:

Meiosis is the spliting of sex cells or chromosomes through the PMAT phase twice. Mitosis is the splitting of body cells such as skin cells ect. and only goes through PMAT once.

Answer:

A

Explanation:

Meiosis occurs in two phases. Meiosis I is the reductive phase, while meiosis II is non-reductive. The point at which the cells first become haploid is at the end of meiosis I, after homologous chromosomes separate.

-----------------------------------------------------

Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).  

After DNA replication there are two meiotic phases.  

1. In the first phase, Meiosis I:  

Cytokinesis occurs

2. In the second phase, Meiosis II:  

Cytokinesis occurs.  

To answer this question, focus your attention on Meiosis I. During the anaphase homologous chromosomes separate. After this point, the nuclear membrane forms in the telophase, followed by cytokinesis. The result is two haploid cells.

Answer:

its important for gametes to be haploid so when fusion of the Male and female gametes take place after fertilization the correct amount of chromosome numbers specific to the species can be restored

It is important for gametes to be haploid as just to maintain the chromosomal number. It is present for the sake of incorporation of both of the sets of chromosome in the progeny.

It is having 23 pairs of chromosomes that is having total of 46 chromosomes.

Because meiosis just  creates cells which are destined to be  the gametes  and in this reduction in the  chromosome number is just  critical that is  without the process, the union of the  two gametes  that are during  the fertilization that will result in  the offspring with just  twice of normal number of the  chromosomes.

Haploid cells in the  humans are just produced out  by meiosis. This is type of  the cell division in which the  single diploid parent cell  just divides to just  produce four with the non-identical  type of the haploid daughter cells. In  meiosis is just  used to get the type of the  produced  type of gametes and is are a  necessary kind of  precursor to  the sexual reproduction.

The answer should be A - Ribosome because during protein synthesis, ribosomes assemble amino acids into proteins and ribosome’s are the cellular structures responsible for protein synthesis.

hope this helps!

Ribosomes assembles amino acids to create proteins. The correct option A.

Ribosomes are the organelles responsible for assembling amino acids to create proteins in cells. Ribosomes are composed of RNA and proteins, and they exist either freely in the cytoplasm or attached to the endoplasmic reticulum (ER).

During protein synthesis, the ribosomes read the genetic information encoded in mRNA (messenger RNA) and facilitate the process of translation. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes, where they are joined together in the correct sequence to form a protein chain.

Thus, the ideal selection is option A.

Answer:

C

Explanation:

because fertilization is the fusion of male gamete and female gamete that arises from meiosis

Answer:

If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

Explanation:

The consequences of an incomplete/absent "S" stage in a cell cycle are ;

The absence or incomplete "s" stage of the cell cycle occurs when the a cell does not completely copy its chromosomes or when there is a significant damage to the genetic material ( DNA ) of the cell. when any of these abnormalities occurs the "s" phase stage of the cell cycle will not be activated until the cell chromosomes are correctly copied. Therefore the cell will not move to the G2 phase of the cell cycle

Hence we can conclude that The consequences of an incomplete/absent "S" stage in a cell cycle are ; A programmed cell death  and The cell will not move to the G2 phase of the cell cycle
