Answer:
Mr. Smith is not justified, Mrs. Smith can not be blamed necessarily for being unfaithful
Explanation:
Widow's peak is a dominant trait which means that it will be expressed both in homozygous and heterozygous condition. If "A" is the dominant allele and "a" is the recessive allele, the trait can be represented as AA or Aa.
Both Mr. Smith and Mrs. smith expressed the trait so they can either have AA or Aa genotype. If even one of them had AA genotype all the offspring would have the trait. But if both of them are heterozygous for it:
A a
A AA Aa
a Aa aa
There is 75 % probability of the child to have the trait (AA or Aa) but there is also 25% probability that the child does not express the trait (aa). Their second child belongs to this category and hence Mrs. Smith can not be blamed for being unfaithful.

Answer:
The central nervous system receives information from the external and internal media, and upon any change or alteration sends an order to the endocrine system to compensate for the change, working together to maintain homeostasis.
Explanation:
The central nervous system (CNS) is in charge of coordinating and regulating the activity of the whole organism, including the activity of the endocrine system.
- The body has multiple internal and external receptors that perceive any change or alteration of the internal environment, and transmit it to the CNS.
- In the CNS the information is processed and a response is elaborated, which is sent to the effector organs.
- If the change or alteration requires being regulated by hormones, the effector is the endocrine system, in charge of synthesizing and secreting those hormones.
This <u>coordinated work that exists between the CNS and the endocrine system</u> makes it possible to correct any imbalance in the internal environment and to maintain homeostasis.
