Answer:
Areas where the myelin sheath has degenerated
Explanation:
Multiple sclerosis is a disease of the nervous system where the myelin sheath is damaged, and impairs its ability of conducing signals in the affected nerves, causing serious deficiencies in many life aspects (movements, sensations, cognition etc).
Answer:
Insulin > Glucagon.
Explanation:
The blood glucose level in the body is maintained by the two hormones known as insulin and glucagon. These hormones are released by the beta cells and alpha cells of the pancreas.
The insulin decreases the blood glucose level whereas glucagon increase the blood glucose level. The individual is hypoglycemic means that he has low blood glucose level in his body. At this condition, the body has high insulin and low glucagon level in the body.
Thus, the answer is Insulin > Glucagon.
Answer:
A clonagem é a obtenção de duas células idênticas com o mesmo código genético que o produto da reprodução assexuada.
Nos mamíferos, a clonagem ocorre através de células somáticas, onde há um núcleo doador e um oócito que se unem por meio de um choque elétrico, formando o embrião que resultará em um ser vivo clonado, um exemplo de essa era Dolly, a ovelha.
Explanation:
Na clonagem de mamíferos, o embrião é responsável por ter caracteres da ovelha doadora, ou seja, será a imitação do código genético desse animal que empresta a célula doadora ao úbere.
Answer:
Charles Darwin went to the Galapagos Island(s).
Explanation:
Charles Darwin took a boat to the Galapagos Island(s) to study plants and animals that proved to show some similarity between each other, such as two finches, which is actually one of his most popular discoveries.
The production of egg and sperm cells follows a certain sequence of events.
The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.
Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.
Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.
