People with poorly controlled diabetes are at risk of amputation due to damage of nerves in the extremities of the body. This damage to nerves is caused by chronically high blood sugar. The condition, when it is caused by uncontrolled blood sugar is called diabetic neuropathy.<span>Diabetic neuropathy mostly affects the feet and they lose feeling, such that an affected person cannot sense pain. When they develop an ulcer or small injury to the feet, it may often go unnoticed and with time become infected. High blood sugar impairs the normal healing process and the injury or ulcer may not heal quickly thus compounding the problem. The outcome of this is that the infected part e.g. a toe, may fester and even become gangrenous putting the whole bod at risk and thus the only away to save the rest of the body is removal by amputation.</span>
Sunflowers grow on a large stalk, and often only produce one flower. paddy plants produce many small flowers, with heavy pollen.
Relaxin
<span>Relaxin, secreted by the corpus luteum of the ovary as well as the placenta, is responsible for helping to inhibit uterine activity and to soften the cervix and the collagen in joints. Softening of the cervix allows for dilatation at birth; softening of collagen allows for laxness in the lower spine and so helps enlarge the birth canal. The effect of estrogen is to cause breast and uterine enlargement. Progesterone has a major role in maintaining the endometrium, inhibiting uterine contractility, and aiding in the development of the breasts for lactation. Human placental lactogen (hPL), also known as human chorionic somatomammotropin, serves as an antagonist to insulin, making insulin less effective, thereby allowing more glucose to become available for fetal growth.</span>

Reproductive cells are haploid (have 1/2 the chromosomes), whereas somatic/body cells are diploid (have the full set of chromosomes)
This makes sense if you think about it. Using the example from the question, every dog has 78 chromosomes. This includes two of each (there are two chromosome 1's, two chromosome 2's, etc. This is visible in the karyotype attached). One set of these chromosomes were inherited from the mother, and one set from the father. Each parent contributed 39 chromosomes (one chromosome 1, one chromosome 2, etc.). If the dog in the question were to have 78 chromosomes in its sperm cells, it would contribute two sets to its offspring. When combined with the chromosomes in the egg cell, the offspring would end up with extra chromosomes. Therefore, both the sperm and the egg cells will have 39 chromosomes, one of each. When combined, they will produce offspring with 78 chromosomes, the proper number.
What Happens during Prometaphase? When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles.
