Answer:
The correct answer of the function of the follicle stimulating hormone in male is the development of the gonads, which is the testis (A).
Explanation:
Sertoli cells, which are responsible for maintaining the maturity of sperm cells due to the production of proteins that bind the androgen is stimulated by the Follicle stimulating hormones. Also, the increase in the size of the testis, the male's gonad, is stimulated by the same Follicle stimulating hormone.
Answer:
Answer: (b) Appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because of the nodes having meristematic cells. These cells are responsible to control the growth and development of tissues and organs in plants.

Answer:
4, 3 5, 1, 2.
Explanation:
The events of muscle contraction begins from the presynaptic neuron, which cause the influx of Ca+, and the release of acetycholine neurotransmitter into the synaptic cleft.
The Ach, binds with the receptors in the sarcolemma, leading to opening of Ligand gated Na+ channels. Therefore Na+diffuses in, causing depolarization, and propagation of action potential along the sarcolemma spreading to the T-tubules.
This is followed by opening of Calcium channels leading exist of Ca+ from the sarcoplasmic reticulum.
The Calcium binds with the troponin, and Tropomysoin exposed the myosin binding sites on the actin filament.Thus cross-bridge is formed by the myosin head with thin filaments which shortened the sarcomere, leading to contraction of muscle fibres.
I think it is false because they still have the old ones
False. Interphase is not technically a part of mitosis.
During interphase, the cell is performing its normal functions and preparing for mitosis.
