What are the steps of meiosis
zlopas [31]

Answer:

In meiosis I there is prophase I, metaphase I, anaphase I, and telophase I and then in meiosis II there is prophase II, metaphase II, anaphase II, and telophase II.

Explanation:

In meiosis I we have;

Prophase I in which a pair of homologous chromosomes line up and form a tetrad. This is the stage during which genetic recombination occurs.

Metaphase I occurs, during which the homologous chromosomes line up opposite each other at the metaphase plate. The chromosomes orientate themselves randomly, thus homologous chromosomes are distributed randomly to daughter cells .

In Anaphase I, homologous chromosomes move to opposite sides of the cells but sister chromatids remain together. Each cell now has 23 chromosomes.

Telophase I in which the homologous chromosomes move to the poles and cytokinesis occurs. Two daughter cells are formed.

In meiosis II we have;

Prophase II (note: there is no interphase as seen in mitosis) during which chromosomes start to move to the metaphase II plate. There is no replication.

Next is metaphase II when the chromosomes align at the metaphase II plate.

In anaphase II the sister chromatids separate from each other and move towards opposite poles.

Lastly, in telophase II cytokinesis occurs again and four daughter cells are produced. Each of the four daughter cells has 23 chromosomes.

Living cells require constant access to energy in order to remain alive. Which statement BEST describes why cells need a constan
docker41 [41]

Answer:

D) Energy is required in order to maintain homeostasis--without a constant, organized internal state, the cell will die.

Explanation:

Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance.

Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping at an appropriate temperature (37º C) ensuring that the necessary changes to the body occur; and thus the cells of the body develop.

Because of homeostasis, cells need a constant supply of energy. That's because energy is needed to maintain homeostasis - without a constant, organized internal state, the cell will die.
