Dafna11 [192]

Answer:

Protein/enzyme synthesis

Explanation:

<em>The process of synthesis of protein in the cell is mainly responsible for the increase in the protein content of the cell.</em>

<em>The process which is also known as the translation process of gene expression takes place at the G1 and G2 phases of the interphase of the cell cycle.</em>

bagirrra123 [75]

Answer:

1, 4, 5 are true. 2, 6, 7, 9 are not true. 3 and 8 are not known.

Explanation:

According to the information we have gathered from the vehicles sent to Mars and the data they collected and analyzed, "Minerals of types known to form in liquid water" on Mars. There is "abundant water ice" and also "dried-up river beds".These statements actually exist.

"Surface pools of liquid water" does not exist on Mars. "A network of straight-line canals", "cities built by an ancient civilization" and "frequent rainfall and snowfall" also do not exist on Mars according to the data.

We do not have any information to prove the existense of "underground pockets of liquid" and "microscopic life" but they are possibilities.

I hope this answer helps.
