Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.

The process that is directly responsible for the formation of the bud on the hydra is;

If a chromatographic column is not placed in a vertical position, the flow and the separation rate of the materials which are been separated may be negatively affected, that is, it may be slowed down, this is because the column is not inclined in the same direction as the flow of the separating substances. Also, collecting the products of the separation will be a bit difficult. If the column is placed in a vertical position, then a test tube can be placed at the end of the column for collecting the separated product
Active transport because it is moving from a lower concentration to a higher concentration
Hi there,
The structure of a lipid influences the lipids function by A phospholipid has a charged head and an uncharged tail and lipids contain fatty acids and glycerol.
Lipids are excellent energy reserves.
Hope this helped :)
have a great day
