Answer:
it is the movement of ions/molecules across a cell membrane into a higher concentration region which is assisted by enzymes and requiring energy
Explanation:
cellular energy to reach this movement
They build and transport proteins.
B.
They allow for cellular motility.
C.
They provide an outside barrier to the environment.
D.
They assist with cellular respiration.
The mitochondria, often known as the powerhouses of cells, primarily aid in cellular respiration, which is the process of turning food energy into energy that cells can utilize. Therefore, the statement 'They assist with cellular respiration' best defines their function.
The mitochondria are often described as the powerhouses of the cell because they are primarily responsible for converting the energy in food into a form that cells can use. The process through which they do this is called cellular respiration.
This function is accurately described in option D: 'They assist with cellular respiration'. During cellular respiration, mitochondria break down glucose and other organic molecules to produce ATP, which is the main energy currency of the cell.
While mitochondria have other functions, including contributing to cell death (apoptosis) and cell signaling, their primary role is in energy conversion through cellular respiration. So in the given options, the statement that best describes the function of the mitochondria is 'They assist with cellular respiration'.

An atom of sodium contains 11 protons, 12 neutrons, and 11 electrons.
An atom of sodium (Na) with an atomic number of 11 has 11 protons, and the atomic number represents the number of protons in an atom. The mass number, 23, represents the total number of protons and neutrons in the nucleus. Therefore, the number of neutrons can be calculated by subtracting the number of protons from the mass number, which gives us 23 - 11 = 12 neutrons.
Since sodium is a neutral atom, the number of electrons is equal to the number of protons. Therefore, one atom of sodium contains 11 electrons.

The answer to this would be C.
As children grow, they gain more cells due to multiplication.
I believe this would be C!
