Answer:
The correct answer is D
Explanation:
The cell membrane is essentially composed of the following:
- phospholipids
- cholesterol
- proteins
The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.
There are 3 main factors that greatly influence the fluidity of the plasma membrane:
- temperature
- cholesterol
- saturated and unsaturated fatty acids
The plasma membrane and cell wall are two different structures. The cell wall is the outermost structure of plant cells, providing rigidity. The plasma membrane lies just inside the cell wall.
The answer is A. Removing waste.
All cells reproduce by duplicating its DNA & dividing into two (MITOSIS), Cells MUTATE resulting in incorrect changes to DNA; mutation occurring over many generationsCells are all living things are made up of cells. Cells are the basic units of structure and function in living things and Living cells come only from other living cells.
I'm not sure but I'd say A. Myofibril
