The synapse is the junction present between two neurons.
In a synapse, the electric impulses are transferred in the form of chemical molecule, which is also known as neurotransmitter. The synapse receives the signals from the sender neuron also known as presynaptic neuron to the receiver neuron, also called as postsynaptic neuron.
Hence, the correct answer is option c. junction between a sending neuron and a receiving neuron.
Answer:
The offsprings of this punnet square will be Dd, Dd, dd and dd in a ratio 1Dd : 1dd

Explanation:
This question involves a cross involving a single gene with alleles D and d where allele D is dominant over allele d i.e. D will mask the phenotypic expression of d in a heterozygous state.
This cross is between a heterozygous parent (Dd) and a homozygous recessive parent (dd). Parent Dd will produce gametes D and d while parent dd will produce gametes d and d.
Using these gametes in a punnet square, four possible offsprings with two distinct genotypes will be produced. The genotypes are: Dd and dd in a ratio 1:1
Hence, the possibility of having a heterozygous dominant offspring is 1/2 while the possibility of having a homozygous recessive offspring is also 1/2.
Depends on two factors: mass and distance.
I think the correct answer from the choices listed above is the second option. A mutation occurs in a brain cell. This mutation will be passed on to other body cells. Cells produced when the mutant cell divides. Hope this answers the question. Have a nice day.
