Answer
C) Viruses need a host to survive
In science, a theory is a hypothesis, and a law is a statement of a observed phenomenon proven to be true.
- A theory explains why a natural phenomenon occurs.
- Scientific laws summarize a set of observations about a natural phenomenon that was witnessed.
- Both can be revised, used to make predictions, and are based off of a hypothesis.
<span>The answer is "Meiosis".
Meiosis is a cell division process which forms four daughter cells which are different from parent cell. Formed daughter cells have half of chromosomes when compared to parent cells. Hence, Daughter cells are haploid (have single set of chromosomes). This process occurs in the sexually reproductive organisms and formed daughter cells can be either sperms or egg cells according to the gender of living being.</span>
Answer:
emigration
Explanation:
The emigration of an animal, in this case of the antelope, is the cause of the lack of food.
The animals are in constant search of food and better places to cohabitate. Antelope is leaving its herd to find a better place for food and even if it sounds strange, animals are also behaving as individuals in case there is threatening of hunger.
The answer is <span>Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.</span>
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
<span>In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.</span>
