Before we answer your question, let's put your data into a Punnet square. The problem says that two heterozygous individuals will mate, so that means their phenotype is Pp.
P p
P PP Pp
p Pp pp
When you read a Punnet square to look for gentoypic ration, it refers to the Genotype, or let's just say the code and just count how many genotypes combinations you see out of the total, which in this case is 4.
PP = 1 out of 4 = 25%
Pp = 2 out of 4 = 50%
pp = 1 out of 4 = 50%
When we look at phenotype, we look for the trait that is expressed. If that is the case, you should remember that the dominant trait is ALWAYS expressed over the recessive. So if the genotype is Pp, the trait of the P is going to be expressed.
Polka-dot (P) = PP and Pp = 3 out of 4 = 75%
Solid (p) pp = 1 out of 4 = 25%
So looking at the result, the answer would then be B. 75% chance of a polka-dot tail and 25% chance of a solid tail (25%PP, 50%Pp and 25%pp).
Answer:
2.Biotic factors are dependent on abiotic factors for food and protection.
3.Abiotic factors affect the type and number of organisms that live in a particular ecosystem.
Explanation:
An ecosystem is an environment that contains both living and non-living parts that actively interacts together.
The living part of the ecosystem is the biotic factors and the non-living parts are the abiotic factors.
- The biotic components actively depends on the abiotic component for nourishment.
- This is exemplified through the process of photosynthesis.
- Also, the shelter of organisms are derived from the abiotic factors.
- The abiotic factors have significant impact on the type and number of organisms that live in an ecosystem.
Answer:
Mutations in the gene result in an alteration of the protein so that epithelial cells are defective in transporting these ions out of cells. Because less salt is secreted from the cells lining these airways and ducts, there is less water "drawn out" of the cells.

<span>D. By gaining energy from warm water
As warm air from warm water rises in a tropical depression, the air pressure below the depression becomes lower. As higher air pressure air from areas outside the depression move into the same space, that warm air from warm water becomes wetter, warmer and rises as well. The result is a stronger system of clouds and wind powered by the heat of the ocean which causes the depression to become more and more powerful.</span>
<span>Choice (B) is the correct answer. Water-mist sprinklers are the newest technology in sprinkler systems. These allow for less water to be used overall while still attaining the same level of fire extinguishing. Instead of using a shower that soaks everything underneath, a fine mist will still put the fire out while possibly saving some areas of the building from damage.</span>
