41. C.DNA is made up of proteins, which tells a cell how to function
42. <span>C. So they can move materials from one area of the cell to another quickly
A DNA is made of proteins which was synthesized by ribosomes of the cell to produce protein and these proteins are churned into mRNA and then these mRNA and used to catalyse the DNA production. DNA of a cell in the nucleus is the programmed individuality that controls, manages and organises the entire cell to function and initiate cellular activities.
It is more efficient, thus, to move materials quickly.

Answer:
c. flows through... are recycled in
Explanation:
In an ecosystem, energy gotten from the sun by plants flows through the ecosystem from one trophic level to another, as the energy in is transformed from one form to another via nutrition.
On the other hand, chemical elements in the form of nutrients are recycled and made available to primary producers when decomposers in the ecosystem to break down organic matter. During decomposition, energy is released. Several nutrient recycling process have feedback mechanisms that ensures chemical elements are recycled back into the ecosystem as they are being used up by organisms.
The answer is D , all of the above
The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell. A cell is the smallest part of an organism that still contains that organism's elements.
Backcross, the mating of a hybrid organism, offspring of genetically unlike parents,with one of its parents or with an organism genetically similar to the parent.
