Answer: Can not get carbohydrates and will die from the lack of energy!
Explanation: The plant will be unable to produce carbohydrates and will die quickly from the lack of energy and because green light is not absorbed by the photosynthetic pigments.
Answer:
a) A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell. FALSE
Explanation:
The regulation of cell fluid is caused by molecules called as Electrolytes. The higher concentration of these electrolytes outside the cells or lower concentration inside the cells will suck water outside the cells. Water is pumped to the area where the concentration of electrolytes is high. It is also clears from the Option d) that water follows the movement of electrolytes so it means that water will move to out if the concentration of electrolytes outside the cells is high which will cause shrinkage of cell organelles.
Answer:
to contract a muscle, myosin and actin filaments shorten, requiring ATP binding and hydrolysis
Explanation:

Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
Pretty sure that the answer is A
