All of the traits combined that actually show up in the individual - this is the phenotype (the physical, observed expression of genes

Each person has two genes. The DOMINANT TRAIT will show up if that trait is present on one of the two genes.

The RECESSIVE TRAIT can be hidden by the dominant trait. It will only show up if a person has both genes for that trait.

An observable form of an inherited characteristic - A trait

The traits that an individual has inherited, including the ones that do not show up - this is the genotype, as it accounts for the set of genes in our DNA

Vedmedyk [2.9K]
The correct answer is "hi<span>s primary caregiver can calm him down easily after being separated".

Starting at 6 months of age up to the age of 2 years old, a child may experience what we called separation anxiety. At this age, the child is able to represent in its mind that what he cannot see does not exist. This is manifested by signs of extreme neediness of the child. When the child eventually outgrows this phase, then the child is now securely attached and the caregiver can calm him down easily after being separated.</span>

24. Name two types of pathways that help a body maintain homeostasis, and an example of each.
gavmur [86]

Answer:

See the answer below

Explanation:

Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways

  • <em>Negative feedbacks</em>
  • <em>Positive feedbacks</em>

Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat

Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.

PLEASE HELP!!!! A Carp fish has 104 chromosomes. Explain why its germ cells CANNOT go through MITOSIS to create egg or sperm cel
I am Lyosha [343]

Answer:

Mitosis can be described as a type of cell division in which the daughter cells are exactly similar to the parent cell. On the other hand, as a result of meiosis, the daughter cells made have half the number of chromosomes as compared to the parent cell.

The egg cells and the sperm cells divide by meiosis instead of mitosis because when the egg cell and the sperm cell will unite, the resulting zygote will maintain the stable number of chromosomes. For example, the egg cell of the carp fish will have 52 chromosomes, the sperm cell will also have 52 chromosomes. When this egg cell and the sperm cell unite, then only a stable zygote with 104 chromosomes will be formed.

If the zygote had 104 chromosomes and the sperm had 104 chromosomes (if they divided by mitosis), then the resulting zygote would have  208 which will not be stable.
