How do enzymes impact a chemical reaction?

andreyandreev [35.5K]

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

What gives sperms motility

Mandarinka [93]

Answer:

The tail of the sperm, the flagellum

Explanation:

We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.

Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.

Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.

The Seven Sisters are seven stars located more than 400 light-years away in the Taurus constellation and they can be seen here w

Ghella [55]

Answer:

Option B

Explanation:

The seven stars are bigger in size as compared to the size of the sun. Also, these stars are more luminous as compared to sun. However, these stars appear small in size in comparison to sun because of their distance from earth. The larger is the distance, the dimmer is the star. Sun is at a distance of 0.0000158 Light years from Earth while the nearest star of the seven sister i.e Alpha Centauri is 4.37 light years away.

Hence, option B is correct

How is dna methylation used in dna repair?

Cloud [144]

DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription.

Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.

grin007 [14]

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
