that expend energy to regulate some or all of their internal conditions are
known as regulators. Regulators are organisms that can control their internal
environment regardless of external environmental change. Regulators achieve this
by homeostatic mechanisms and it requires a lot of energy. Examples of
regulators are mammals and birds</span>
A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.
The answer your looking for is B different patterns of gene expression
this ones simple all the others don't use sunlight because they cant make food within themselves but plants on the other hand use direct sunlight to make their food unlike the others. ;]
If it is more salty it means that the water is hypertonic to the hypotonic potato and if the water is less salty then the water is hypotonic to the hypertonic potato
