A.
Animal cells are very close to plant cells, but they have one key difference that separates them; the cell wall.
A cell wall is a thicker layer on the outside of the cell membrane. These are unique, and are <u>only found in plant cells.</u> Animal cells just have the cell membrane as their outer part. This enables them to change shape due to the membrane being very flexible.
Plant cells do not change, and only conform to their cell wall's shape. This enables them to grow up (literally) to help gather sunlight and enable photosynthesis.
Herbivores grass eater , carnivore only eat meat, omnivore eat grass and meat, decomposer decompose things <span />
The answer should be B the DNA is damaged so new cells grow and create tumors etc.
<span>Here square frequency of recessive alleles r^2 = 160/1000 = 0.16
Therefore r = 0.16
Since r + d = 1; d = 1-0.16 = 0.84</span>
Channel protein is important because it is embedded in the membrane and it also covers the membrane. This is important because the channel must transport the micromolecules and ions in and out of the cell. Carrier proteins are important because the carrier must transport the molecule in and out of the cell.
