Answer:
Lining up of chromosomes in the cell
.
Explanation:
Prophase begins with the Thickening of chromosome. Chromosomes are clearly visible inside the nucleus. each chromosome splits longitudinally to form two chromatids.
The centriole in the centrosome of animal cell divides into two. The centrosphere set the centrioles free. Centrioles develop very fine eye-lash like thread called aster rays. the two asters start moving towards the opposite poles. By the end of prophase they reach at the opposite poles.
Well what I know of it’s coal
The right answer is BB or BO
The blood group is inherited through a gene located on chromosome 9. Call it the ABO gene. The ABO gene exists in 3 forms, called alleles. We inherit one of these alleles from each of our parents.
The combination of these two alleles is called genotype. The blood group that results from this combination is the phenotype.
* B and B give the BB genotype, which means at the phenotype level, blood group B.
* B and 0 give the B0 genotype, which means at the phenotype level, blood group B, because B is dominant.
Answer:
If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.
