Answers

Answer 1

Answer: Mitosis is a four-stage process that creates two identical cells from one original cell. In Mitosis chromosome the cell divides intotwo identical sets daughter nuclei. in mitosis the mother cell divides into two daughter cells which are genetically identical toeach other and to the parent cell.Meiosis is a reduction cell division where the number of chromosomes is divided into half. In Meiosis it gametes formationsoccur in animal cell and meiosis is necessary for sexual reproduction. The meiosis has 6 phase: Meiosis I, Prophase I ,MetaphaseI, Anaphase I, Telophase I, Meiosis II

With respect to acetylcholine, botox is to nicotine as _____ is to _____.

Answers

Answer:

antagonist to agonist

Explanation:

Glutamate has excitory effect on the nerve fibres in the central nervous system. It is mostly found in synaptic vesicle of nerves terminals in abundance and can be released through exocytosis. The glutamate has special transporters on the plasma membrane that allow it to be transported across neurons.

A drug increases the effect of the neurotransmitter is called an agonist. If it decreases the effect of the neurotransmitter it is called an antagonist. If the neurotransmitter is excitatory like glutamate above, nicotine presence will increase the excitatory effect, and presence of botox will decrease the excitatory effect by inhibit its diffusion across the neurone.
