<span>The ischemic penumbra can maintain metabolic demand with marginal blood flow from collateral circulation for a maximum of 50% before increasing in size. A penumbra is the area where the flow of blood at about 25 - 50% can maintain normal metabolic demands for 6 - 8 hours only. When it continues to increase, the human cells will die and other neurological activity will be suspended causing the person to die slowly.</span>

Read each of the sentences that describe a phase of meiosis. Place each sentence into the correct box.
Allushta [10]

Answer:

prophase 1(Homologous chromosomes pair to form a tetrad.

prophase 1(Crossing-over may occur between the non-sister chromatids).

Metaphase 1 (Homologous chromosomes line up at the center of the cell.)

Anaphase 1 (Homologous pairs separate and move towards opposite ends of the cell)

Telophase 1 (A nuclear membrane forms and cytokinesis follows).

Metaphase 2 ( The haploid number of duplicated chromosomes line up at the metaphase plate.

Anaphase 2 (Sister chromatids separate and become daughter chromosomes that move to the poles)

Meiosis 2: Four haploid daughter cells are formed that are not genetically identical.

Explanation:

Meiosis is a type of cell division that gives rise to gametes ( offsprings). This type of cell division occurs only in the reproductive organs. A diploid cell has two sets of chromosomes: one from the female parent and the other one from the male parent. When the diploid cell undergoes meiosis, the chromosome replicate once and the nucleus and cell duplicate twice giving rise to four haploid gamete cells.

The phases of meiosis occurs in two step divisions. Homologous pairs separate during the first round cell division which occurs in MEIOSIS 1 while the sister chromatids separate in the second nuclear division called MEIOSIS 2.

In each round of division, cells go through four stages: PROPHASE, METAPHASE, ANAPHASE, and TELOPHASE. The specific events that occur in these stages are already listed in the above answer.

Generally, at the start of meiosis, each member of a homologous pair of chromosomes, which are made up of two chromatids, moves to lie side by side. While they are thus paired, genetic material is exchanged between the chromatids. This is known as CROSSING OVER.

When the nucleus divides for the first time, the chromosomes in a given pair( not the chromatids) separate and move to opposite ends of the cell. This results in only half the number of chromosomes going to each daughter cell.

During the second nuclear division, the chromatids separate and move to opposite ends of each daughter cell giving rise to four gamete cells, each with a haploid number of chromosomes.
