Answer:
True
Explanation:
According to Mendelian's law of inheritance, the dominant allele is the allele that is expressed in an individual while the recessive allele are usually not expressed in the phenotype of an individual.
If a parents is dominant for a particular allele of tallness and recessive for a particular allele of shortness it is observed that the dominant allele is what is expressed in the phenotype of the offspring and inherited in simple Mendelian fashion by the offspring.
Answer:
I think they're neither perpendicular nor parallel
Explanation:
Not parallel since slope of e (3/5) isn't equal to slope of f (-8/3)
Not perpendicular since the product of their slopes isn't equal to - 1.
=> (3/5)(-8/3)= - 8/5 and not - 1
(plz make sure you typed the equations correctly.)

A mutation in either a hormone or its receptor might affect the physiological system that it normally regulates by either blocking hormone effect or creating a completely different effect.
Hormones can be called chemical messengers which coordinate distinct functions in the body. Many glands, organs and tissues produce and release hormones, many of which constitute the endocrine system.
A hormone will only act on a part of the body if it fits i.e. if the cells in the target tissue have receptors which can receive the message of the hormone. Given that hormones carry instructions in their structure, mutations alter their structures by changing nucleic acid sequences which blocks hormone function.

The correct answer is: B. A person spends one hour each day under the ultraviolet rays of a tanning bed.
The relationships between ultraviolet (UV) light and skin cancer are highly positive because it has been shown that indoor tanning bed use represents an avoidable risk factor for melanoma and non-melanoma skin cancer. UV light is a form of radiation that causes mutations in DNA by causing the chemical changes that alter the shape of the DNA. So, UV light is a potent mutagen and thus, tanning bed (source of UV light) can cause damage to the DNA in the surface layer of your skin after repeated or prolonged exposure. This might increase the risk for skin cancer.
