The reproductive cycle in females is regulated primarily by HER HORMONES. Five hormones to be exact. These hormones are Estrogen, Progesterone, Luteinizing hormone (LH), follicle stimulating hormone (FSH), and gonadotropin releasing hormone.
Estrogen is from the ovaries. It helps regulate the menstrual cycle. It promotes the rapid growth of cell linings in the uterus to prepare for implantation resulting to pregnancy.
Progesterone is also from the ovaries. It is produced after ovulation and maintains the health of the lining within the uterus during pregnancy. If no pregnancy occurs, the progesterone level decrease and results to menses or monthly period.
Gonadotropin Releasing Hormone is secreted by the brain as a result of the hormonal changes that occur every month. It in turn stimulates the production of FSH and LH.
FSH stimulates the follicles inside the ovaries increase the amount of estrogen and progesterone produced in the first two weeks of the menstrual cycle.
The increase in estrogen level by FSH prompts the pituitary glands to release LH. Luteinizing hormone then signals the dominant follicle, made by FSH inside the ovaries, to release its eggs for possible fertilization.
Answer:
Evolution is a change in the inheritable phenotypic characters within a population occurs through successive generations.
Explanation:
Evolution is a change in inheritable characters of population during a period of time by means of natural selection. These changes in phenotypic characters brings the formation of new species. Darwin's theory consists of three categories,individuals within a group are variables, variations are inheritable,all individuals with variables survive.
According to Darwin's theory states that survival is based on selective mode like particular phenotypic characteristics or behavior given to some individuals who are able to survive in a particular environment.
Answer:
a
Explanation:
since runoff can be caused by little rainfall but in abundance of vegetation then it may decrease since they stop or slow down it's flow but runoff can not be affected by rocks since the velocity may even wear it
Answer:
Antiparallel: A term applied to two molecules that are side by side but run in opposite directions. The two strands of DNA are antiparallel. The head of one strand is always laid against the tail of the other strand of DNA
Answer:
Explanation:
1 kJ = 1000joules
15kj = 15000 joules
1 Megajoules = 1000000 Joules
3.5 mj = 3,500,000 joules
1kj = 1000joules
0.2Kj = 200 joules
