Meiosis.
Meisois is is the reproduction of the sex cells (sperm and egg), while mitosis is between a regular cell. Another difference is that Meiosis splits into 4 cells, while mitosis splits into 2.
Hope this helps!
Its not necessry when it must happen but it happens both before MEIOSIS and MITOSIS !!
hope this help you ....................
Answer:
little available genetic variation
Potential for exploiting hybrid vigor in wheat is limited wheat is predominantly outcrossing
Explanation:
Pure lines are varieties with little genetic variation. Pure lines are generated from crops that have undergone selection to the point of uniformity this is done to reduce variation that may occur genetically and to get varieties that are the same genetically.
Pure lines are they are the same genetically with no segregating genes. variation or changes in pure lines is mostly associated with the environment. wheat is an outcrossing crop generating a pure line will help have good vigour as selection would have been done to generate varieties that are strong and high yielding.
Answer : Comparative Effectiveness Research
Answer:
Glucagon.
The receptor has seven transmembrane a helics secreted by pancreatic a cells.
Polypeptide.
Stimulate glycolysis and glycogenesis in the liver.
EPINEPHRINE.
Stimulated muscles cell to breakdown glucogen.
Amino acid derivative.
Released in response to stress.
EPINEPHRINE AND GLUCAGON.
Released in response to a drop in glucose levels.
Explanation:
Epinephrine is called adrenaline hormone, it is secreted by the medula of adrenal gland. It is an amino acid derivative, it stimulate muscles cells to breakdown glucogen. This hormone is released in response to body stress.
Glugagon is a peptide hormone that is secreted by alpa helics of pancreases. It prevent blood glucose from dropping. It stimulate the conversion of glucogen to glucose in the liver which is release to the blood stream.
The two hormones is released in response to drop in glucose levels to increase glucose concentration in the blood.
