The answer is A. The first cell is in the anaphase I and the second cell is
in the anaphase II.
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 meisosis 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>
It's because a blueprint is something that is like the backbone of something. It forms whatever the project is. Dna is what forms us and creates us.

Answer:
The five categories of vertebral column are:
- Cervical
- Thoracic
- Lumbar
- sacrum
- coccyx.
Explanation:
The 26 vertebrae of the spine or vertebral column are classified into five categories based on the structural differences between them. The first category is cervical and is made of seven cervical vertebrae. The spines of cervical vertebrae are shorter than that of others and have bifurcations.
The next category is the thoracic and is made of twelve thoracic vertebrae. Thoracic vertebrae are followed by lumbar region made up of 5 lumbar vertebrae. Spines of thoracic vertebrae are longer and are directed downwards while that of the lumbar vertebrae project towards the posterior region. the sacrum is present below the lumbar region and consists of five fused sacral vertebrae. The last category of spine is coccyx. It has four fused coccygeal vertebrae.
