guajiro [1.7K]

Answer:

- Dependent variable: number of cells that are in one of the phases of mitosis

Explanation:

In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.

Why is it so important for scientists to calculate exact amounts of products used by
Vsevolod [243]

Answer with Explanation:

When it comes to the study of the outer space, <u>astronauts play a vital role in giving people significant information regarding their exploration.</u> Most of the missions last for 6 months in space and this is followed by another mission lasting at the same time or so.

When astronauts travel, <em>they need to bring exact amounts of products that they will be using during their expedition.</em> These products are particularly related to personal items that they need in order to survive. However, <u>these items have to be calculated in terms of their weight, since the space craft can only accommodate a certain amount of mass. </u>

The collective term for the personal items is "Personal Preference Kit" or the "PPK." It is said that an astronaut can only carry up to 20 personal items and the total weight should only be<em> 1.5 pounds. </em>

Thus, this explains the answer.

The frequency of autosomal alleles K and k in a large population of snails is 0.6 and 0.4. What is the approximate genotypic fre
Flura [38]

Answer:

Option (b).

Explanation:

The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.

The heterozygote frequency can be calculated by the formula:

F = \frac{2Kk-H}{2Kk}

Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.

Put the values in the above formula

0.3 = \frac{2\times2\times0.6\times0.4-H}{2\times0.6\times0.4}

H = 0.36 ≈ 0.34.

Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.

Hence, the correct answer is option (b).
