It occurs when particles spread
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.
I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.
B) the glass cylinder helps in measuring because you can read the labels on the side of the cylinder and also it can heat the substance without the cylinder melting like the plastic one, or giving off heat to fast like the metal cylinder <span />
