<h2>B) option is correct </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
In artificial selection, breeders select superior breed for the breeding purpose so that this type of selection favors the superior genotype and eliminates inferior genotype, thus leading to genetic drift
Stabilizing selection is a type of natural selection in which intermediate genotype is favored but extreme genotypes (inferior and superior) are eliminated
In the given example of pigmentation in pigeons, breeding is selectively done with intermediate pigmentation hence intermediate genotypes will be favored
Answer:
Because of the difference in surface area to volume ratio
Explanation:
Surface are to volume ratio is the area of an object that is exposed to the external environment (surface area), compared to the amount within an object (volume).
Therefore an elephant has a lower surface area to volume ratio than a mouse.
The smaller an object is the greater its surface area to volume ratio.
Small animals have much more surface area per mass than large animals. With so much surface area, they lose heat very quickly. So, a mouse, with a lot of surface area per mass, must spend a lot more energy to stay warm than a large animal.
Answer: A
Explanation:
Karyotypes can be used to screen for and confirm chromosomal abnormalities such as Down's syndrome, and there are several different types of abnormalities which may be detected.
Kinetic chain checkpoints represents the six anatomical locations of predictable movement patterns and is denoted as option B
<h3>
What is Kinetic chain checkpoints?</h3>
These are groups of body segments, connecting joints, etc which have a connection to the spine in the human body.
They work together to ensure body parts are easily moved and makes the detection of movement dysfunctions easier.
