Answer:
look at the pictures
Explanation:
1. If we cross the parental generation which is RR x rr, the probability of the F1 generation to get rough coat is 100% and they will be a carrier of the recessive trait smooth coat.
Since the phenotypic ratio is 100% heterozygous Rr, in crossing the F1 to get the F2, we will use the genotype Rr. To get the F2, use the cross Rr x Rr.
The phenotypic ration for F2 is 3:1. There is 75% to get rough coat and 25% smooth. The answer is based on the result on the Punnett square. On the other hand, the genotypic ratio is 1:2:1. There is 25% probability to get RR genotype, 50% Rr, and 25% rr.
2. Since the two parental mice got 6 albino offspring and 5 brown mice offspring, it is approximately 50%. it takes a parental mice who is Brown that is carrying an albino trait crossed with an albino to get offspring with almost the same number. Therefore, the genotype of the brown mice is Aa.
because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.
<h3>What exactly are fossil fuels?</h3>
Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.
Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.
Some examples of fossil fuels are petroleum, coal, etc.
The missing options of the question are:
- peat is a fossil fuel because rewetting it takes only 3-5 years.
- peat is a fossil fuel because the total time for restoration is lengthy.
- peat is not a fossil fuel because it has biologic origins, making it a biofuel.
- peat is not a fossil fuel because humans can promote the replenishment of peat.
The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.
Thus, the correct option is B.

Answer: absorption
Explanation: “The process or action by which one thing absorbs or is absorbed by another.”
In this case, matter and energy is absorbed.
The potato crop devastation occurred in Ireland for not using one single potato species.
Explanation:
Potato became the staple crop of 18th Century Ireland and was easy to grow in the soil of this place. Later, it became the most dependent crop of the people of Ireland which made its supply very demanding leading to the yielding of more than one species of potatoes.
This yielding reduced the variety in the genetics of potatoes that helped in preventing the disease that affect potatoes by making the Irish people susceptible to famine. The Phytopthora bacteria affected the potatoes of North America in the year 1840 and Ireland’s moist weather in that same year made the blight to thrive.
