AP Biology - If 72 out of 200 individuals....(pic is attached) - worth 25 points!
Answer:
A.) 48%
Explanation:
AA = dominant genotype
Aa = heterozygous genotype
aa = recessive genotype
Hardy-Weinberg Equations:
p² + 2pq + q² = 1 p + q = 1
In this equation, In this equation,
-----> p² = frequency of "AA" -----> p = frequency of "A"
-----> 2pq = frequency of "Aa" -----> q = frequency of "a"
-----> q² = frequency of "aa"
(Step 1)
Determine the frequency of the recessive allele ("a").
72 / 200 = 0.36 recessive phenotype
The only way to have the recessive phenotype is to have the recessive genotype, aa. Therefore, q² = 0.36.
If q² = 0.36, then q = 0.6 (take the square root).
(Step 2)
Determine the frequency of the dominant allele ("A").
p + q = 1
p + 0.6 = 1
p = 0.4
(Step 3)
Determine the frequency of the heterozygous genotype ("Aa").
If -----> p = 0.4 and q = 0.6
Then -------> 2pq = 2(0.4)(0.6) = 0.48
0.48 x 100% = 48% Aa

The measure of how stretched out an ellipse is, is referred to as ____.
A. Gravity
B. Weight
C. Mass
D. Eccentricity
D. The measure of how stretched out an ellipse is, is referred to as eccentricity.
What is eccentricity of ellipse?
Eccentricity for an ellipse is the ratio of the length of the semimajor axis (a) to the distance (c )between the ellipse's center and each focus.
e = c/a
The greatest ellipse has the smallest eccentricity, whereas the perfect circle has the maximum eccentricity. The eccentricity of an ellipse e, which ranges from 0 (the limiting case of a circle) to 1 (the length of the ellipse), is used to determine how long it is (the limiting case of infinite elongation, no longer an ellipse but a parabola). Because the distance from the fixed point on the plane has a constant ratio that is less than the distance from the fixed line on the plane, the eccentricity of an ellipse ranges from 0 to 1.

Answer:
Ingestion is when food comes into the body through the mouth and down the esophagus. Digestion begins with chemically with enzymes in saliva, and mechanically with the teeth, and continues when food (as a bolus) enters the stomach to be dissolved by acid and pepsin. Food (chyme) then goes into the small intestine where nutrients are absorbed through the villi. Waste is then eliminated through the large intestine, rectum, and anus.

Doubling the amount of water a person drinks daily.
Drinking caffeinated beverages several times a day.
An increase in alcohol consumption
Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response. Frequent episodes of intoxication, obsession with alcohol, use of alcohol in spite of negative effects, and a need to seek out and use alcohol are all signs of alcoholism developing.

The cichlid is a colorful fish found in freshwater lakes. There are over a thousand species of cichlid fish today. If a species of cichlid became extinct, the niche the fish filled within the ecosystem would be left open. Explain how an available niche after extinction can lead to speciation.
The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.
When does speciation occur?Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.
With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.
