Which of the following is not a piece of molecular evidence supporting the endosymbiotic theory?

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

Which of these processes does not require the cell to use energy A cell division b protein synthesis c DNA replication D diffusi

weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

Which digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine?.

blsea [12.9K]

Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.

A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.
