Answer:
b. di uses across a synaptic cleft from a neuron to a muscle cell.
Explanation:
A neurotransmitter is di uses across a synaptic cleft from a neuron to a muscle cell. Neurotransmitters are chemicals which enable neurotransmission. In reaction to an impulse a motor neuron axon secretes a neurotransmitter and causes the muscle fiber to contract. It is a chemical messenger which passes on the signals across the chemical synapse.
Answer:
<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.</em>
Explanation:
The cross for the offsrings that will be produced by F1 generation is shown below:
a a
A Aa Aa
A Aa Aa
As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.
A cross between the F1 generation will give the following results:
A a
A AA Aa
a Aa aa
This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.
