Which step is meiosis is shown in the image below ?

Answers

Anaphase I of meiosis in shown in this image.

What do you mean by meiosis?

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.

Answers

Answer:The option are not given, here are the options gotten from another website.

A. Aerobic respiration

B. Electron Transport Chain

C. Anaerobic respiration

D. Krebs cycle

The correct option is C.

Explanation:

This is because anaerobic respiration is a type of respiration that produced ATP. pyruvate are metabolize in the absence of oxygen by a process called fermentation and fermentation us anaerobic respiration. And fermentation is the chemical process where glucose or substrates are broken down in the absence of oxygen by the activities of enzymes. When pyruvate are metabolize in the absence of oxygen , it will produce lactate.

In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.

In biology, an incomplete oxidation process is called fermentation, which does not require oxygen to take place, and which produces an organic substance as a result.

Fermentation consists of a process of glycolysis (breakdown of the glucose molecule) that produces pyruvate (pyruvic acid).

As it lacks oxygen as a receptor for the excess electrons of the NADH produced (nicotin adenine dinucleotide), it uses an organic substance that must be reduced to reoxidize the NADH to NAD +, finally obtaining a derivative of the initial substrate that is oxidized.

In this process, then, neither the mitochondria nor the structures linked to the cellular respiration process are involved.

Only 2 molecules of ATP are produced per molecule of glucose consumed.

It is carried out by the muscle cells that ferment glucose when the oxygen input is not enough to continue breathing.

Therefore, we can conclude that many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.

Answers

all cells are near a vein and therefore can obtain water and release glucose quickly. three differences between the cells of the palisade mesophyll and the cells that make up the other areas within the leaf.

Veins sustain the leaf and carry nutrients and energy through the leaf and to the rest of the plant via xylem and phloem, respectively.

How does the location of the veins in a leaf affect how well they function?Veins in plants transfer water, nutrients, and energy to the rest of the plant while also giving it structure and support. Plants employ their vascular system to transport water and nutrients when they absorb them through their roots.Veins support the leaf and transport nutrients and energy to the rest of the plant via xylem and phloem, respectively.Because every cell is near a vein, it can rapidly collect water and release glucose.

Answer:

Identification of cockroaches is limited here to  adults. A major source of confusion is the recognition of adults from nymphs.There are  subjective differences, as well as morphological  differences. Immature cockroaches are known as  nymphs. Nymphs closely resemble adults except  nymphs are generally smaller and lack wings and  genital openings or copulatory appendages at the  tip of their abdomen. Many species, however, have  wingless adult females. Nymphs of these may be  recognized by their shorter, relatively broad cerci  and lack of external genitalia. Male cockroaches  possess styli in addition to paired cerci. Styli arise  from the subgenital plate and are generally conspicuous, but may also be reduced in some species.  Styli are absent in adult females and nymphs
