Answer:
B. 25%
Explanation:
Assuming the trait for teeth size is represented by the allele A. large teeth size is dominant and will be represented by A while small teeth size will be represented by a.
Assuming that the population of 1,000 [piranhas are all heterozygotes and they crossbreed with one another:
Aa x Aa = AA, Aa, Aa and aa
The ration of piranhas with large teeth to that of the small teeth is 3:1 or 75:25.
Hence, about 25% of the next generation of the population is ecpected to have small teeth.
The correct option is B.

Answer:
Because some effects will occur.
Explanation:
The positive test which was the result for the organic molecules for the water sample showed that there is some change occurs in water sample by adding of organic molecules due to which the results of the test comes positive. If there is no change occurs in the water sample by adding some organic molecules so the results will come negative which means no effect.
Answer:
30, 000 plaques.
Explanation:
Plaques may be defined as the clear zones or spots that indicates the lysis of the bacteriophages. These plaques are useful to count the number of progeny phages.
The formula used to calculate the phage is as follows;
Plaques progeny = [Number of plaques observe/(Dilution factor x Volume of diluted virus)]
Since, in the given question the dilution factor and volume is not given and it can be taken as unity.
Plaques progeny = 30, 000 / ( 1 x 1)
Plaques progeny = 30, 000.
Thus, the answer is 30, 000.
The most likely way that the lost fat left the body of a person on a strict diet and exercise regimen who lost 7 kg (about 15 pounds) of body fat in just two weeks is (A) It was released as CO₂ and H₂O.
Fats are the lipid molecules made of a glycerol backbone with 2 fatty acids and a phosphate head group. The body of an organism uses fat as an energy source, but it is the predominant form of storage of energy in the body. Fats can be of two types: good fat and bad fat. Only the food fat consumed in required amounts is beneficial for the body.
Strict diet is the calorie-restricted diet with fixed timings of meals. The restrictions and timings vary from person to person. When a person follows a strict diet along with exercise, beta-oxidation occurs inside the body where the fat is lost in the form of carbon dioxide and water.
