The Venn diagram makes a comparison between categories. Intersection: Cell division/Asexual: diploid, somatic, mitosis, genetically identica/Sexual: haploid, gamete, meiosis, chromosomes separate , genetically different.

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

   

A Venn Diagram is represented as two or more circles with some degree of superposition between them. It is used to make comparisons expressing similitudes and differences between things.

Each circle represents a category -in this example, sexual and asexual reproduction-.

The superposed area is named intersection and shows things in common between the two categories.

We already know that sexual reproduction occurs by the process of meiosis, while asexual reproduction occurs by mitosis.

In superior organisms, there are two types of cells: Somatic cells and germ cells.

The somatic cells are diploid (2n), meaning that each cell has a pair of equal chromosomes. The somatic cells are all the body cells except for the sexual ones, and they reproduce by the process of mitosis.

In somatic cells, one of the sets of chromosomes is inherited from the maternal side, while the other homologous set of chromosomes is inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells is diploid, 2n.

Mitosis is a process through which, from a diploid somatic cell (2n), two identical daughter diploid cells (2n) are produced.

First, occurs duplication of the cell content, and then the separation into two new cells happens.

Germ cells suffer mitosis and meiosis.  

Through meiosis, germ cells produce gametes, called sperm and egg cells, through the gametogenesis process.  

Gametes are haploid (n) with half the number of chromosomes that might be found in the somatic cells.  

During gamete formation, the pairs of homologous chromosomes separate after crossing over. Then, sister chromatids also separate. The result is the formation of four gametes.  

Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.

Gametes' destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization.

The zygote is a complete cell that suffers successive mitosis to form the new organism.

If a cell that is about to divide has 22 chromosomes how many chromatids does it have? How many centromeres does it have?

Answers

44 chromatids 2 centromeres

44 chromatids 2 centromeres, If a cell that is about to divide has 22 chromosomes.

What are chromosomes?

In the synthesis phase, the number of chromatids doubles while the number of chromosomes remains constant. Although the number of chromatids is unaffected, anaphase doubles the number of chromosomes.

Depending on whether or not the DNA has replicated and when the sister chromatids split, the chromosome changes during the cell cycle.

Meiosis I and Meiosis II are the two division cycles that occur during a meiotic cell division. Since the genetic material duplicates during the S phase of meiosis I, there will be 2n chromosomes during metaphase I.

Therefore, if a cell that is about to divide has 22 chromosomes it have 44 chromatids and 2 centromeres.

A disease-causing bacteria successfully enters your body, making it past the first and second lines of defense. Which barrier will then act on the bacteria? chemical physical biological electrical.

Answers

Answer:

The correct answer is biological.

Explanation:

When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.

Green eyes

Explanation:

The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer.

The rarest eye color in the world is green, only 2% of the population in the world have green eyes. To find out more about the list.....

1. Green eyes

Only 2% of people in the world are believed to have this eye color. It is most easily found in northern and Southern Europe and Western Asia.

2. Amber eyes

They are reddish-brown, with a golden and coppery undertone. Among the clear and beautiful eyes in the world, and according to the survey, the most iris, all eyes and beautiful in the world are according to the study, all eyes are rare and specific.

3. Red or violet eye

It is generated by the body thanks to some genetic changes. The most common is albinism, a disease that lowers melanin levels. Because of this, the hair and eyes can be distinguished.

With this information, we can conclude that there are several eye colors, but the most rare is the color green.

if a plant is not green (does not contain chlorophyll) can it do photosynthesis? why or why not?

Answers

Answer:

No, it cannot carry out photosynthesis because the plant will not be able to absorb light as it does not have chlorophyll.

Explaination:

Chlorophyll in plants is used for absorbing energy from light. And, in photosynthesis, light/sunlight is one of the main factors needed, so as the plant cannot absorb light, photosynthesis can't take place.

how the development of the microscope played an important part in helping to convince people that mendel was right​

The microscope can be used to demonstrate the segregation of chromosomes during cell division. The law of segregation of characters is a Mendel's Law.

Each allele or gene variant is located at a specific chromosome location known as a gene locus.

The Law of Segregation indicates how one offspring receives one allele from each parent for each locus in a diploid organism.

The development of microscopy confirmed the idea that offspring receives one allele (which is located at a specific chromosome) from each parent for each gene locus.
