Answer: it deals with synthetic or superficial genes and traits like color, markings, size, and speed.
Explanation: a good example of artificial selection is breeding dogs. people mix breeds to get these kinds of quality’s.
Artificial selection is the opposite of natural selection, in which organisms adapt to their environments without human intervention. So, the correct option is C.
What is Artificial selection?Artificial selection, commonly known as selective breeding, is the intentional breeding of particular plants or animals by humans to advance certain desirable traits. On the other hand, natural selection occurs in the wild when organisms with favorable characteristics are more likely to survive and reproduce.
The term "artificial" in artificial selection refers to deliberate human manipulation of the reproductive process as opposed to allowing natural processes to occur. The use of nutrition, hormones or artificial insemination is not mentioned. A wide variety of traits, including color, markings, size, movement, and other physical or behavioral characteristics, are possible through artificial selection.
So, the correct option is C.

What
type of mutation causes this the sequence AGTATA to become AGTATTA
Answer:
Insertion
Explanation:
Mutation is generally referred to as any change or alteration that occurs to the nucleotide sequence of a gene. There are several types of mutation depending on how it occurs. The types of mutations are; substitution, insertion, deletion, etc.
Insertion mutation is a type of mutation in which one or more nucleotide base is added a sequence. This is the case in this question about an original sequence that reads: AGTATA. We then have the mutated sequence as follows: AGTATTA
Notice that, nucleotide "T" has been added in between T and A. Hence, a type of INSERTION mutation.

The brachial plexus is associated with which of the following?
A. Innervation of the upper limbs
B.Innervation of the lower limbs
C.Axillary nerve is a terminal branch
D. A and B are correct
E. A and Care correct
Answer:
innervation of the upper limbs
The brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.
What is the brachial plexus?It is responsible for providing the motor (muscle), sensory and sympathetic innervation of the upper limb.
Through it, the spinal cord is connected with all the peripheral nerves of the upper limbs and all the sensorimotor information of these segments is also transmitted.
Therefore, we can conclude that the brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.

12. Individuals with Type O blood are able to produce both Anti-A and Anti-B antibodies, while individuals with Type AB blood produce neither of these antibodies. Explain why this is the case. How does this relate to the idea that people with Type AB blood are often referred to as universal recipients for transfusions
Answer: Blood group O individuals are able to produce Anti- A and Anti- B and are often referred to as UNIVERSAL DONORS, while blood group AB individuals produces none and are often referred to as UNIVERSAL RECIPIENTS
Explanation:
Two antigens, type A and type B, occur on the surfaces of the red blood cells in a large proportion of human beings. These antigens are referred to as agglutinogens because they often cause blood cell agglutination during blood transfusion. Because of the way these antigens are inherited, people may have neither of them on their cells , they may have one or they may have both simultaneously.
When type A antigen and type B antigen is not present in an individuals reb blood cell as seen in blood group O, antibodies known as Anti-A and Anti- B develops in the plasma. This is because small amounts of type A and type B antigens enter the body through food, bacteria and other ways and they initiate the development of anti A and Anti- B antibodies in their plasma.
Furthermore, individuals with blood type AB has antigen A and B on their red blood cells and therefore do not develop antibodies A and B in their plasma. This makes them universal recipient as their blood do not discriminate any ABO blood group during blood transfusion.

Villi and microvilli help to absorb nutrients in your small intestine.
True
False
Answer:
True
Explanation:
Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
Answer: TRUE
Explanation: Villi are folds on the small intestine lining that increase the surface area to facilitate the absorption of nutrients. Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food.
So, the correct option is 'True'.

Why are people who go to strip clubs generally NOT considered to be voyeurs?
Group of answer choices
The nudity of the performers is not complete.
There is no sense that people who go there are doing something frowned on by society.
The performers are consenting to being seen by the audience.
The performers are exhibitionists and it's impossible for someone to simultaneously be an exhibitionist and a voyeur.
Answer:
The performers are consenting to being seen by the audience.
Explanation:
A voyeurist experiences pleasure from observing someone else having sexual relations, undressing, or performing any sexual activity. The voyeurist does not have the person's consent to watch, and they find ways to do it from a distance or with discrepancy. Part of their pleasure is from observing the person without consent, and another part is from observing the person engage in sexual activities. They do not desire to be in a sexual relationship with the observed person; they want to watch.
People who go to strip clubs do not observe from afar and hiding from the performer. They have the consent of the performers, which is the opposite of what attracts a voyeurist.
