Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26

enzymes function most efficiently are the temperature of typical cell, which is 37 Celsius increases or decreases in temperature

Veronika [31]

The information given about enzymes suggests that the enzymes have the capability to change their size at higher temperatures which affect their activity.

<h3>What are Enzymes?</h3>

Enzymes may be defined as biocatalysts that perform the important function of increasing the rate of a chemical reaction without being consumed in the process. It may be thought that all cellular reactions and processes are mediated by enzymes.

Temperature is a physical property that can significantly affect the activity of enzymes. It results in the denaturation of enzymes, irreversibly altering their structure. Enzymes perform their most suitable activity at the temperature of 37°C.

Therefore, the information given about enzymes suggests that the enzymes have the capability to change their size at higher temperatures which affect their activity.

The modern synthesis brought together Darwin's theory of evolution with Mendelian genetics. Why was this so important?

MakcuM [25]

Answer:

Option C

Explanation:

Options for the question are

a. It demonstrated that nothing in biology makes sense except in the light of evolution.

b. It demonstrated that species arise from other species.

c. It provided a quantifiable mechanism to explain gradual evolutionary change.

d. It was the first time that change in biological organisms was observed.

e. It was not very important to evolutionary biology.

Solution -

The term modern synthesis by coined by Julian Huxley and the goal of this synthesis was to understand and determine how genetics bring evolutionary changes in a population and with this objective it combined the Darwin’s theory of evolution and Mendel’s work on heredity. Later on scientist Dobzhansky under this synthesis found that genetic mutation causes variation through the process of natural selection and hence lead to evolutionary changes in a population even if they are isolated for a long time.

Hence, option C is correct
