Answer:
Peter's parents genotypes: hh and hh
Peter's possible genotypes: HH or Hh
Gretchen's concern: The legitimacy of Peter's parent is doubtful
Explanation:
Assuming hairy shoulders allele is represented by H and non-hairy shoulder allele by h. H is dominant over h, hence, for someone to have a hairy shoulder, he/she must posses one H allele (Hh or HH).
Peter's parents do not have hairy shoulders, hence their genotypes will be hh and hh.
Peter has hairy shoulder, hence, his genotype is either HH or Hh.
Gretchen is concerned because neither of Peter's parents have hairy shoulder. This means neither of the parents have the hairy shoulder allele (H). The concern of Gretchen would be about the source of Peter's hairy shoulder allele. If neither of the supposed parents have the allele, where did he get his allele from?
The legitimacy of Peter's parents is questionable and this is why Gretchen is concerned.
Answer:
The land between the water has become more prevalent because due to droughts, the water has evaporated and dropped.
Explanation:
The number of protons and electrons will be equal, so the element has 41 electrons.
Synapse
A synapse is a junction where there is a small gap between the neurons.The synapse permits the flow of electrical or chemical signals from neuron to neuron, allowing these neurons to communicate and pass information among themselves.
The chemical synapse converts the electrical signal to a chemical response by releasing chemicals called neurotransmitters, which are received by receptor sites in the other neurons. The electrical synapse allows the flow of ions from one neuron to another to pass the electric current or signal.
Answer:
Explanation:
Changes in Earth's system affects the growth of life on Earth. Since Earth has gone through so many stages and different stage has different growth of life. Life on Earth includes all the living things such as plants animals humans microbes etc. All take part in different cycles such as carbon cycle and nitrogen cycle and can influence global climate by changing chemical composition of atmosphere.
