Answer:
The correct answer is -
the neurotransmitters are broken down in the synapse
The presynaptic neuron absorbs the neurotransmitters
Explanation:
The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.
This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.
Answer: tt
Explanation: If the allele for a trait is recessive, it has to have 2 of that recessive allele to show that trait.
Answer:
Cytokinesis is the process of the cell cycle which divides the cytoplasm of the parent cell into two cells.
The process of cytokinesis involves the membrane of the cell, so the process differs in plant and animals cell as the plant cell exhibits two layers that are the cell wall surrounding the plasma membrane while animal cell lacks the cell wall. the main difference in both the process is:
1. Plant cell division-occurs by cell plate formation while animal cell division- occurs by full cleavage.
2. In-Plant cell- no cytoskeleton is involved while in animal cell- Cytoskeleton components are actively involved
3. Plant cell division is centripetal while animal cell division is centrifugal
4. Plant cell-wall formation is present while animal cell-Wall formation is absent
The similarities in both the process are that it generates the genetically identical daughter cells. In both cells, cytokinesis after the karyokinesis and is the last stage of the division.
Answer:
Bombyx mori, the domestic silk moth, is an insect from the moth family Bombycidae. It is the closest relative of Bombyx mandarina, the wild silk moth. The silkworm is the larva or caterpillar of a silk moth.
