Answer:
This makes it a heterozygous allele and the dominant allele with be expressed.
For example:
T is for tall and t is for short
The heterozygous allele is Tt, which makes the allele "heterozygous tall"
Answer: The Parathyroid gland
Explanation:
The Parathyroid gland secretes "Parathormone", an hormone that exerts
- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood
- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.
Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland
Answer respiration system
Explanation:
cause
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.
From first to last,
1) Pioneer species like grasses and flowers grow
2) Bushes begin to dominate
3) Trees become common and outcompete other plants for sunlight
4) an intact ecosystem is disrupted by a natural disaster
5) The climax community for the area is established once again
