Skeletal, smooth, and cardiac muscles fall into what category of organization?
pishuonlain [190]

Skeletal, smooth, and cardiac muscles fall into <u>organ system</u>.

Organ System- The organ system is the collection of organs that cooperate to carry out a certain task in the body of an organism. Organs, that are self-contained collections of tissues like the heart that cooperate to carry out a single function, are present in the majority of animals and plants. The circulatory system, musculoskeletal system, and digestive system are a few instances of organ systems and their functions.

Tissue- Tissue is a collection of cells with a common structure and function that work as a single unit. The body's tissues give it shape and aid in energy storage and heat retention.

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.
