Answer:
The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).
Explanation:
Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.
The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.
The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.
Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
Answer:
You would need to add new enzyme.
Explanation:
The irreversible inhibitor permanently renders the enzyme inactive, so the only way would be to add more enzyme.
Answer:
The answer is 97%.
Explanation:
The zika virus' 1% incidence rate in the population has no effect over the probability of the patient being infected or not. If the test has a 3% false positive rate that means that if it is positive, the results have a 97% chance of being true. Therefore the chance that the person who took the test and had a positive result being actually infected is 97%.
I hope this answer helps.
RR x rr
or if you're using the letter "t" to represent the alleles TT x tt
Homozygous means that a particular gene has identical alleles on both chromosomes. TT is for a dominant (stronger) trait and tt is for a recessive (weaker) trait.
Hope this helps! :)
