The answer is <span>A. p2 = 0.36, 2pq = 0.48, q2 = 0.16.

Let's first distinguish alleles frequencies from genotypes frequencies:
p - a frequency of R allele,
q - a frequency of r allele,
p² - a frequency of RR genotype,
2pq - a frequency of Rr genotype,
q² - a frequency of rr genotype.
<span>The gene frequency of allele r changes from 0.38 to 0.40, thus:
</span>q = 0.40
Now, we will implement this in the following equation:
p + q = 1
If q = 0.40, then:
p + 0.40 = 1
⇒ p = 1 - 0.40
⇒ p = 0.60
Now, the frequencies of both alleles are know and it is easy to calculate the <span>genotype frequencies:
-</span> the frequency of RR genotype: p² = 0.60² = 0.36
- the frequency of Rr genotype: 2pq = 2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² = 0.16
Therefore, the new genotype frequencies in that population are <span>p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span>
Starfish move slow because of the material that is on the body. Also because they have a water vascular system. Water goes into the canal and they move based on that system.
Why don't you got to the beach and look at that part;)

Answer:
Here is the full question:
(A) If a closed container contains a mouse as well as enough food, water, and oxygen for the mouse to live for 3 weeks,
How much will the container weigh 1 and 2 weeks later after the mouse has eaten, drunk and exercised (respiration is CO2 emission), and why?
(B) If the mouse was in a wire cage and only the weights of the mouse, food, and water were considered, would you come to the same answer as in (A) and why?
Explanation:
(A) The mouse will weigh the same. This is because solids, liquid, and gases cannot escape the closed container. All of the life processes involving reactions conserve the atoms involved. Some of those atoms will appear in the form of gases, some as solids, and others as liquids but all will be retained in the closed container.
(B) In a wire cage, gases can escape. This means that the weight will not be the same after 1 and 2 weeks. The weight would be less than the original weight of the mouse, it's food, and it's water.
Placing solar panels on the roof of every home would be beneficial to the environment because solar panels produce energy but not greenhouse gases.
<h3>What are Solar panels?</h3>
Solar panels are structures composed of materials capable of absorbing solar radiation in order to be converted into electricity, thereby representing a renewable source of energy.
In conclusion, Placing solar panels on the roof of every home would be beneficial to the environment because solar panels produce energy but not greenhouse gases.
