The correct option is B.
Prokaryotic cells are primitive cells which have no true nucleus and membrane bound organelles while eukaryotic cells are cells that have true nucleus, membrane bound organelles and well defined structures and layouts. Although the two cells are quite different from each other, they share some similarities and one of this is cytoplasm. Cytoplasm is present in the interior compartments of both cells.
Answer:
During exercise your cells need energy to function. in order to do so they harness it through ATP. In order to get ATP the cells convert it to ADP usually through aerobic respiration. Aerobic respiration requires oxygen to function and the cells will use up all their oxygen stores for it. Cells will get more oxygen when the exercise has been completed through the pulmonary system delivering oxygenated blood to the cells and taking away the used CO2 rich blood.
<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.

Answer:
The diagram which shows the formation of two daughter cells is mitosis.
A human body cell has 46 chromosomes when mitosis in a human body cell occurs, the parent cell divides into two daughter cells which has the exact number of chromosome i. e. 46 in each daughter cell. When replication of chromosome occurs, two identical copies of chromosomes are formed.
