Which of the following accurately pairs the phase of the cell cycle with its primary purpose?
babunello [35]
According to a source, the answer is <u>A. M phase–Cell growth before DNA replication.</u><span>

Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>

Which statement is true about atoms that are more stable?
Svetlanka [38]
The stability of atoms depends on whether or not their outer-most shell is filled with electrons.  If the outer shell is filled, the atom is stable.  Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.

Arrange the following estuarine zones in decreasing order of salinity.
Maksim231197 [3]

Answer:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline

Explanation:

Let's first define each of these levels:

- Polyhaline: a category of salinity that has medium-high levels of salt

- Mesohaline: a category of salinity that has medium levels of salt

- Oligohaline: a category of salinity that has low levels of salt

- Euthaline: a category of salinity that has high levels of salt

Now, we can order these in decreasing order of salinity:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline
