The pH indicator bromothymol blue is blue in an alkaline solution and yellow in an acidic solution. A slight increase in acidity

, such as when CO2 gas is added, causes a solution with the indicator to change from blue to yellow. A solution with the indicator would be most likely to turn from yellow to blue when which combination of factors exists? A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.

Ainat [17]
Firstly, start by doing Punnett squares for each of the characteristics. Attached are the three Punnet squares, made by me, as they should look in end.

For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.

\frac{1}{2}Ss×\frac{1}{2}Ll×\frac{1}{2}Rr=\frac{1}{8}SsLlRr

Total offspring×\frac{1}{8}=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.

Feliz [49]

Answer:

The correct answer is option b. "it has high face validity".

Explanation:

Face validity in a test is a very broad concept that simply refers to whether the test appears to be suitable to report what it claims to do. It is important to notice that high face validity in a test only means that the judgers of the test agree that the test is suitable, but it doesn't mean that the test is reliable for the patient and for the therapist. In this example, Kristoff should take other tests and examinations before he could be sure that he is not suffering from depression, particularly because he has many symptoms that indicate that he is depressed.

After a period of rapid growth (log phase), bacterial growth rates will slow and enter the stationary phase. The number of viabl
Stells [14]

Answer:

A. The number of cells that are dying is balanced by the number of new cells that are being formed.

C. Harmful waste products may be accumulating.

D. The cells are likely running out of nutrients.

Explanation:

During the stationary phase, the number of viable cells remains constant. This may be due to a balance between cell division and cell death wherein the total number of newly formed cells and the cells undergoing death are equal.

Nutrient limitation is one of the several factors that make the microbial cells to enter the stationary phase. Depletion of nutrients slows down the population growth.

Accumulation of toxic waste products as it occurs during the growth of anaerobic bacteria also adversely affects the population growth.

For example, the accumulation of lactic acid and other organic acids (by-products of anaerobic respiration) inhibits the growth of the population by making the medium acidic.

Svetradugi [14.3K]

Answer:

2.Less than 73% of the populations would have only one allele present.

Explanation:

The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.

Using a larger breeding population would not be expected to alter the outcome of the experiment.
