The Vascular system transports water and sugars throughout the plant during photosynthesis.
Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.
Answer:
a. mimicry
Explanation:
Stick bugs are perhaps one of the better known examples of insect mimicry. Their twig-like appearance helps to defend them against predators that hunt by sight.
The mosaic nature is due to the numerous proteins that
are entrenched in the phospholipids bilayer, fluctuate in shape, size and
patterns in the same way as the stones or tiles of a mosaic.
the flexibility is due to individual phospholipids molecules which can move virtual
to one another and gives the membrane a flexible structure that is constantly
changing shape
