Answer: Acetylcholine is released from the axon terminal and diffuses across the synapse to link to a receptor in the surface of the motor end plate.
Explanation:
Sinapsis in biology is a structure in which a neuron cell communicates with another using an electric or chemical sign.
Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
Water molecules are polar. This means that one end of the molecule is positively charged, while the other is negatively charged. Opposite charges attract. Water molecules on the faucet that are eventually pulled away from the others by gravity will themselves pull together and form round drops because the charged portions of molecule attract the oppositely charged portions of another.
The geneticist who discovered the white eye mutation in drosophila and helped establish that genes are carried on chromosomes was Thomas Hunt Morgan.
Thomas Hunt Morgan One landmark of modern genetics can be dated to January 1910, when Thomas Hunt Morgan discovered a male of Drosophila melanogaster with white eyes.
What is genetics?
- The study of genes and heredity.
- Heredity is the passing of genetic information and traits from parents to offspring.
- Genetics is the study of genes and tries to explain what they are and how they work.
- children usually look like their parents because they have inherited their parent's genes.
