Answer:
Biodiversity will decrease, and sustainability will decrease
Explanation:
The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
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.
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 duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.
In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
Answer:
A site at the 5′ end of a gene where RNA polymerase attaches to initiate transcription and control of gene expression occurs is called a/an

Answer:
D. It is a random guess about how something happened.
Explanation:
In everyday life, a theory is a hunch or a guess about how something happens (in the scientific method, we might call it a <em>hypothesis</em>).
A is <em>wrong</em>. It doesn’t necessarily explain how nature works, because it hasn’t been tested by experimental testing and observation.
B and C are <em>wrong</em>. They are features of the <em>scientific method</em>.
