Genetic drift results in selection for individuals that are better adapted to their environments. True False

Biology

Answer: False.

Genetic drift is a stochastic process that occurs randomly through time. It refers to random fluctuations in allele frequencies due to chance events (small population size).

Explanation: Factors that can affect genetic diversity are Genetic drift, mutation, selection, migration, non-random mating and recombination.

Of these factors, forces that majorly control the fate of genetic variation in populations are genetic drift and natural selection.

Genetic drift refers to random fluctuations in allele frequencies due to chance events (small population size).

Natural selection involves environmental conditions acting on wild plant or animal populations or species. Most fit in a selection refers to genotype or phenotype with greater average reproductive output over it's lifespan than other genotypes or phenotypes.

Kathy was making liquid growth medium for plants. The pH of the original solution was 8. The optimal pH for plant growth is 6. W
liubo4ka [24]

If referring to the question: Kathy was making liquid growth medium for plants. The pH of the original solution was 8. The optimal pH for plant growth is 6. What was the best compound to add to make it pH=6?

A) KOH

B) HCL

C) Water

D) No answer provided

Then the correct answer would be option B, to add HCL, known as Hydrochloric acid to lower the pH to 6.

In science, pH is a scale used to measure the acidity of a solution or its basicity. The scale ranges from 0 to 14. A pH of 7 would mean that the given solution is neutral, lower than 7 equates to an acidic solution, while anything above 7 becomes increasingly basic.

Option A is to add KOH, or potassium hydroxide to the original solution whose starting pH is 8. KOH is a solution whose pH is above 8,  a strong base, and is often used to increase the pH of a solution. In the question it states what the desired pH is 6, therefore we want to lower, not increase the pH. This makes option A incorrect.

Water is a neutral solution. Even though it is neutral, it is not used to neutralize basic or acidic solutions. Acid or bases may be added to water to create very diluted solutions that are nearly neutral despite containing a strong base or acid, but this is a different process than neutralization and will not give the desired pH. Option C is also wrong.

Option B is correct because HCL, known as hydrochloric acid is a strong acid, commonly used to lower the pH of a solution by increasing the concentration of hydrogen ions. Since we start with a pH of 8 and wish to achieve a pH of 6, HCL is the correct component to add to the solution. Due to option B being correct, option D that states that no answer is provided, is incorrect.

Please help I will give BRAINLIEST face the earth
Oxana [17]

Answer:

It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.

Explanation:

Hope this helps you a lot my boo!
