9. Look closely at the illustration above. a. What process is occurring? b. What is being made? c. How can you tell?
mars1129 [50]
The answers are:

A. DNA replication in the nucleus of a cell
B. From one helix of DNA in a replication process, we get two: The DNA is a double helix and it consists of two strands of specifically connected amino-acids. When the time for replication comes, a set of enzymes unwind the two strands and leave them as a base for additional two strands attaching to them - the green line is an example of that. The free nucleotides - adenine, guanine, thymine and cytosine are left open and the enzyme called DNA-polymerase helps to produce a new strand on the template of the old parental one (one of the blue ones in the picture) 
C. By the location on the smaller picture - replication takes place in the nucleus. And the most important hint are the letters A - adenine, G - guanine, T- thymine, and C-cytosine. A connects with T, and G connects with C.

Finger [1]

Answer:

a. The mtDNA of Anna Anderson bore no resemblance to that of Tsarina Alexandra

c. Tsarina Alexandria's mtDNA was found to be a match to that of the teenage girl.

Explanation:

Mitochondria contain their own DNA known as mtDNA, a strand which is inherited maternally. mtDNA can be used to find maternal ancestry and cannot be passed down by a paternal parent.

This information provides evidence given that the remains of the teenage girl had mtDNA that was identical to the mother, Tsarina Alexandra. It also gave evidence as to why Anna Anderson's claim of being Anastasia were false as the mtDNA of her and Tsarina Alexandra were not similar.

As to why the other answers cannot support the hypothesis, mtDNA is a maternally passed-down strand making the father, Tsar Nicholas Romanov, from having identical mtDNA to his children. On the other hand, if the teenage girl were to not have matching mtDNA to that of Tsuarina's mtDNA, this would disprove the theory of the girl being related to her.

While the teenage boy also had matching mtDNA with the girl, this only proves that the two were related to one another but not necessarily related to Tsarina unless the mtDNA of all three were proven identical.

A cell is placed in a solution that is hypotonic to the cell. Which of the following best describes movement of water in this si
Lera25 [3.4K]

Answer:

C. Water will flow into and out of the cell, but the overall net movement will be into the cell.

Explanation:

In a hypotonic solution, the concentration of water outside the cell is higher than inside the cell and the concentration of the solute is lower than inside the cell, therefore, water will flow in and out of the cell but the net movement of water will be from area having higher water concentration to lower concentration.

That means the net movement of water will be into the cell if a cell is placed into the hypotonic solution. Water moves in and out of a cell by the process called osmosis which is a type of diffusion.

This movement of water into the cell will swell cell and the cell can burst if it is not protected by a cell wall. Therefore the right answer is C.
