Cell membranes do not make nutrients (or energy) for the cells. This is the function of the mitochondria by the electron transport chain, tricarboxylic acid cycle, and beta oxidation. The cell membrane is responsible in holding the cytoplasmic components of the cells. The cell membrane is also involved in substance regulation by acting as a semi-permeable membrane for simple diffusion as well as the site where carrier proteins are embedded for facilitated diffusion (not ATP requiring) and active transport (ATP requiring). The cell membrane is also involved in cell to cell recognition because receptors are also embedded in the cell membrane.
Explanation:
Molecules of reactants and products undergoes chemical changes when they combine.
The combination leads to the breaking of bonds and rearrangement and this brings about the formation of new products.
- Atoms in molecules tends towards stability
- They often want to mimic the noble gases and would keep rearranging until stability is attained.
- This leads to the formation of new compounds in the product end of the reaction.
The answer is C) Send pollutes runoff into nearby ponds.
Answer:
Sternocleidomastoid is the muscle which when when contracted unilaterally, will produce lateral bend of the spine
Explanation:
Sternocleidomastoid muscle is responsible for the turning of neck and its nodding. It consists of long muscles that are able to connect the three process of temporal bones i.e sternum, clavicle, and mastoid. Thus, this muscle can bend the spine laterally.
