Answer:
A
Explanation:
although they may evolve, done if the matter will remain the same.
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.
If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.
An ecosystem is the biotic and abiotic factors which are responsible for the survival of an animal
Answer:
desiccation tolerance, alternation of generation
Explanation:
- Adaptation to life on land, took place by desiccation tolerance that is the ability of the organism to stand or endure extreme dryness and the alternation of generations such as the life cycle changes in which the haploids and diploids change or show haplodiplontic.
- The development of the phloem and xylem tissues for distribution of water and intake up of minerals from the soil. Development of stem for gas exchange. Some plants have defense strategies for the dry environments such as seedless sprout growth.
