A population is solely comprised of 72 A2A2 individuals. 10 A1A1 individuals migrate in and contribute to the mating pool. What is the frequency of A1A2 individuals in the offspring? Answer to 2 decimal places. Hint: Use the Gene Flow table!

Answers

We have that the the frequency of A1A2 individuals in the offspring is mathematically given as

2pq = 0.65

Frequency

Generally the equation for the Hardy-Weinberg equilibrium   is mathematically given as

[tex](P+q)^2=p^2+2pq+q^2\\\\(P+q)^2=1\\\\[/tex]

Therefore

q2= the frequency of individual Al Al

[tex]q2= (72/10+72) \\\\q2= 72/82[/tex]

thus,

P = [10/82]^(1/2)

q= [72/82]^(1/2)

Hence

2pq = 0.65

describe the relationship between temperature ant the enzymatic activity of lactase. of the three temperatures tested , which is the optimal temperature for enzyme activity?

Answers

Answer:

Cooler temperatures slow the rate of lactase's function, while at extremely high temperatures, those above 135 degrees Fahrenheit. For example, lactase can become denatured, or lose its shape. A protein's shape is responsible for its function, so when it becomes denatured, lactase loses its ability to function.

Cooler temperatures cause lactase to work more slowly, whereas exceptionally hot temperatures, such as those exceeding 135 degrees Fahrenheit (ca. 57 °C), can cause lactase to lose its structure and become denatured.

What is the function of lactase enzyme?

The enzyme lactase, also known as lactase-phlorizin hydrolase, is present in mammals' small intestines and is responsible for breaking down lactose (milk sugar) into the simple sugars glucose and galactose.

Lactose is not normally digested and absorbed in the small intestine if your body does not create enough lactase.

Instead, it keeps moving through the digestive system until it reaches the large intestine, where it is partially broken down by bacteria into acids and gases.

Therefore, a protein's activity depends on its form, lactase stops working when it becomes denatured.

Earth’s water cycle shows the interactions among biosphere, lithosphere, atmosphere, and the hydrosphere because it moves from one sphere to another.

Interaction of water cycle with earth systems.

Water present in the hydrosphere can evaporate and this water become part of the atmosphere. Through precipitation, water in the atmosphere comes back to the hydrosphere or percolate into the ground to become groundwater which become the part of the geosphere.

This water is used by vegetation and other organisms which are the part of biosphere so we can conclude that water cycle connects the four earth systems.
