Explanation:
white blood cells are the cells that do not have any shape
The progression of a cell by the cycle of cell is regulated by the protein family Cyclic
Explanation:
- In the year 1982, Cyclin was located by Timothy Hunt as a family of proteins which has a vital function in the progression of a cell.
- CDK enzymes or ‘cyclin dependent kinase’ gets activated by it that synthesizes the cycle of the cell.
- The concentration of this protein moves in a cyclic way in the cell cycle. No enzymatic function is seen in them but it aims at CDK’s different location.
<span>Segregation
For a trait to show or express itself in an individual it must have two types of the same allele (for example P and p) showing on the chromosomes. The showing of both alleles on an offspring's chromosomes means that both parents have the same trait and that is why there is a chance for an allele to become dominant in other words to express itself in the offspring. However if only one allele is transferred in the genes of the offspring that means that the trait that the allele is responsible for, will remain unexpressed.</span>
Answer:
True
Explanation:
Catecholamines refer to the hormones produced by the adrenal gland present on the upper side of the kidney.
The catecholamine hormone includes the epinephrine, norepinephrine and the dopamine.
During stress conditions, the sympathetic division of the autonomic nervous system gets activated which leads to the release of the norepinephrine from the postganglionic neurons and the prolonged-release leads to the release of the adrenaline from the adrenal glands.
Thus, true is the correct answer.
Answer:
This is false as genes are transferred to a fetus from the reproductive cells(sperm, Egg cells)
Explanation:
This is because humans have 46 chromosomes, however this is comprised of the 23 chromosomes in each sperm and egg cells. This shows that genes are not transferred through the blood but by sperm and egg cells. Also genes and chromosomes are stored in the nucleus of cells, however red blood cells do not have a nucleus further showing that this is false.
