Answer:
It is because the axons that fail to find a target cell die thats why every axon in an adult mammal has a target cell (muscle cell or other neuron) with which it makes synaptic contact.
Explanation:
Synapse is basically a structure in the nervous system responsible for the passage of the electrical and the chemical signals from one neuron to another neuron or an effector cell.
Usually the axon is the presynaptic part of the synapse and the postsynaptic part is usually present on the body of the neuron or a dendrite or an effector cell like a muscle cell.
If the axon doesn't make a synaptic contact with the target cell , the axon will die because the neurotransmitters and the chemical mediators will not be released and no action will result on the postsynaptic membrane.

Yes, it is b. Digestion is the process of breaking down food.
Answer:
Frequency of both recessive and dominant allele will change
Explanation:
Let the fox fur be determine by B gene. B is a dominant allele whereas b is a recessive allele. BB and Bb produce brown pelt whereas grey pelt is only produced in recessive condition of bb.
Normally, 80% of the population had dominant allele B and 20% had recessive allele b. But the foxes with dominant trait i.e. brown pelt were hunted due to which dominant allele would be reduced over time. Number of foxes with grey pelt would increase and they would reproduce more grey pelt foxes (bb). Eventually the frequency of recessive allele b would increase in population and frequency of dominant allele B would decrease in population.
