Mutations can occur at higher rates in viruses.

Explanation:

The mutation rate of an organism refers to the rate or average number of errors which are formed in the genome of the organism’s progeny per base per replication cycle.

Accordingly the Mutations of viruses are the highest per base pair per generation mutation. Viruses can mutate more than a million times than the host’s body due to their virulence factor, evolution ability, and presence of a variety of traits.  

Of the DNA and RNA viruses, the RNA viruses like the Retroviruses having a much higher rate, for example, the HIV virus which is a Retrovirus has high mutation rate.

Which of the following would you identify as a correctly written problem statement if your topic was about the negative affects
mafiozo [28]
I think B is the correct answer.  Answer choices C & D are about dolphins, but they do not have anything related to negative effects surrounding human and dolphin interaction.  A, on the other hand, may seem like a good choice, but then again, the answer is too vague.

Cells must be alive to use energy and do work dose passive transport occur in a cell that is dead? Why or why not?
Orlov [11]

Answer:

<h3>Yes, Passive transport can occur in dead cells.</h3>

Explanation:

For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.

A concentration gradient is the difference in the concentration of solute molecules  across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.

The transport of the solvent can occur as well, from higher concentration to lower concentration.
