Answer:
cell membrane is the outer boundary present around the cells functions to protect the inner cellular material from outer invaders and maintain the shape of cell
Explanation:
Cell membrane is the outer most boundary made up of lipids and proteins.
Mainly the membrane is composed of lipid bilayer in which protein chains are embedded
Answer:
D - the production of a specific mRNA will increase as a result of the binding of the hormone receptor complex to the DNA
Explanation:
We are told that the hormone binds a receptor and then enters the cell, binding to the DNA and promoting transcription of a specific gene.
Transcription is the process whereby mRNA molecules are synthesised from a DNA sequence, which are then translated into specific process. D is correct, as the gene the hormone binds to will increase in transcription, producing a specific mRNA.
A, B and C are much more general processes, not linked to the actions of a hormone on a specific gene.
Answer: Given your four choices, the best/most correct one would be (c) the sunlight that evaporated water that eventually falls as rain and fills the reservoir. It is the potential energy stored in the reservoir water which is "released" as it is converted to kinetic energy (the movement of water which spins the hydroelectric generator turbine, etc.), but the absolute source of that original potential energy comes from the Sun's action to evaporate lake or ocean water which is returned to Earth as rain ... and it is this rainwater which ultimately fills the reservoir behind the hydroelectric power plant.

Answer:
If the shape of an enzyme changes then the enzyme will no longer be able to perform its function.
Enzymes can be described as bio-catalysts which usually speed up a chemical reaction. Each enzyme has a particular substrate which fits into the active site of the enzyme. Every enzyme needs a particular temperature and pH for its functioning. If the shape of an enzyme changes, then it will no longer be able to perform its function and will become denatured.
