Scenario #1

Biology
1 answer:
Natasha_Volkova [10]3 years ago
3 0

Answer:

p = 0.36

q = 0.64

p² = 0.13

2pq = 0.46

q² = 0.41

Explanation:

We need to use the Hardy-Weinberg equations:

p + q = 1

p² + 2pq + q² = 1

p: the frequency of the dominant allele

q: the frequency of the recessive allele

p²: the frequency of homozygous dominant

2pq: the frequency of heterozygous

q²: the frequency of homozygous recessive

Here, we know that 328/800 people are homozygous recessive, which means that q² = 328/800 = 0.41.

Then, q = √0.41 = 0.64, and p = 1 - q = 1 - 0.64 = 0.36.

Now, we have p² = (0.36)² = 0.1296 ≈ 0.13 and 2pq = 2 * 0.36 * 0.64 = 0.4608 ≈ 0.46.

The answers are:

p = 0.36

q = 0.64

p² = 0.13

2pq = 0.46

q² = 0.41

How is the speed of light affected as light passes at an angle from air to water
Liula [17]
They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.

Pls hurry im doing an exam Four groups of students plan scientific investigations to answer four questions for the science fair.
mafiozo [28]

Answer:

The correct option is 3

Explanation:

An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.

The third option can be easily answered using the "requirements" above.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.
