Answer:
luteinizing hormone (LH) is mainly used to induce ovulation.
Explanation:
Ovulation refers to the release of an egg.During menstruation ovarian follicle discharges an egg.The egg is also known as an ovum, oocyte, or female gamete. It is only released on reaching maturity.
Ovulation induction uses hormonal therapy to stimulate egg development and release egg or ovulate.
By increasing the production of follicle stimulating hormone (FSH) by the pituitary gland, follicles are stimulated and hence egg growth is seen.
A surge in the Luteinizing hormone (LH) causes the egg to release or ovulate. Luteinizing hormone (LH) is produced and released in the anterior pituitary gland. This hormone is a gonadotrophic hormone and plays an important role in controlling the function of ovaries in females and testes in males.
In women, the hormone stimulates the ovaries to produce oestradiol. Two weeks into a woman's cycle, a surge in luteinizing hormone causes the ovaries to release an egg during ovulation. If fertilization occurs, luteinizing hormone will stimulate the corpus luteum, which produces progesterone to sustain the pregnancy.
Fungi have an equal number of organisms with each body type. This is visible in the diagram, where in front of the kingdom "fungi", the body type is specified as "both".
This means that the proportion of both unicellular and multicellular organisms is equal, which is why "both" is written. Examples of fungi include mushrooms and yeast.
Answer: D
They often occur spontaneously, because when energy is released during a chemical reaction it does not usually happen slowly.
