Answer:i think At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are contained within small sacs called synaptic vesicles, and are released into the synaptic cleft by exocytosis.
Explanation: i hope this answer your question....
Sporophyte generation - It is found in both seed and seedless plant. Dominant phase of the life cycle of the seedless plants is diploid sporophyte while in seed plant male and female gametes fuses to produces a diploid zygote which develops into a sporophyte.
Pollination - It occurs in seed plants only
Sporophyte contains male and female reproductive structures - It is found in both seed and seedless plant.
Single fertilization - It occurs in both seed and seedless plant
Sperm cells transported by water to egg cells - seedless plant only
Answer:
The correct answer is pituitary gland.
Explanation:
The pituitary gland is called the master gland because it regulates the secretion of many other endocrine glands. Pituitary is responsible for the secretion of hormone that regulated the level of estradiol and progesterone during the menstrual cycle.
Anterior pituitary release FSH(follicle-stimulating hormone) and LH(Luteinizing hormone) after it gets stimulation by GnRH secreted by the hypothalamus. FSH help in the production of estrogen by stimulating follicle and LH is responsible for the production of progesterone from corpus luteum. Therefore the correct answer is the pituitary gland.
So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
