The question is incomplete as it does not have the options which are:
A) relay molecule
B) transducer
C) signal molecule
D) response molecule
Answer:
C) signal molecule
Explanation:
The transmission of signals in the neurons takes place in the form of electrical energy and chemical energy. The signals get transmitted in the form of electrical signals inside the neurons but when the signals have to be passed on to the next neuron on the pathway then the electrical signals get converted into the chemical signals.
The electrical signals cause the release of the chemical signals molecules called neurotransmitter from the synaptic vesicles in the presynaptic neuron and also opens the gated ion channels at the terminal.
The neurotransmitter thus acts as a signal molecule in the transmission of a signal through neurons.
Thus, C) signal molecule is the correct answer.
Explanation:
Typical roots contain three different sections, or zones: the meristematic zone, the zone of elongation, and the zone of differentiation. In the meristematic zone, named after the apical meristem, the plant cells undergo rapid mitotic division, creating new cells for root growth.
Answer: The correct answer is- testes → epididymis → vas deferens → urethra.
Sperms are the male reproductive cells that are produced during spermatogenesis ( process of gamete formation in males).
Sperms are produced in seminiferous tubule ( that lie within testes) and the they migrate to epididymis ( where they are stored and matured). Sperms travel from epididymis to a muscular tube that is called vas deferens. Finally, sperms are propelled towards urethra via ejaculatory duct.
