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

During replication, is the original dna sequence maintained in the new strands? explain why or why not.

Jobisdone [24]

Hello!

During replication, DNA sequence is maintained in the new strands

The reason for it is the action of DNA Polymerase. This is an enzyme who has the function of "proofreading" the DNA sequence to ensure that all nucleotides are in the right order. This process is so accurate that an incorrect base is introduced every 10⁹-10¹⁰ bases.

Concentration of sodium (Na ) outside of the cell is lower than it is inside the cell. However, the cell utilizes a membrane pro

solong [7]

Answer:

True, by active transport

Explanation:

The influx and efflux of molecules through the cell membrane depend on the concentration gradient.

When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.

When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.

In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
