Answer:
True, polar covalent bond
Explanation:
A covalent bond is one of the types of the chemical bond which is formed when the electrons are shared between the two atoms.
Based on the magnitude of the sharing of electrons between atoms two types of covalent bonds are formed which are: pure covalent bond in which the electrons are shared equally whereas the polar covalent bond in which the electrons are shared unequally between two atoms.
Since there is a type of covalent bond formed which has unequal sharing of electrons called polar covalent bond therefore true is the correct answer.
Answer:
True
Guard cells close openings in the leaves slowing down water loss.
Answer:
c) Breaks down and inactivates acetylcholine
Explanation:
Acetylcholinesterase is an enzyme that is required for termination of acetylcholine activity in the synaptic cleft. The enzyme is present in the extracellular side of the motor endplate membrane and breaks down the acetylcholine into acetyl and choline.
In the absence of acetylcholine, the muscle fibers resume their resting stage. Therefore, acetylcholinesterase activity is required for the normal functioning of muscles and nerve cells that use acetylcholine as a neurotransmitter.
The answer would be D, evolved from a common ancestor

The answer is c. Starch.
During
photosynthesis in the leaves of the plants, carbon dioxide and water are converted into glucose and oxygen
using the energy of sunlight. The excess of glucose synthesized in
photosynthesis is converted and stored as a starch which is than transported into storage organs where it will serve as a long-term energy storage.
Fat is used for long-term energy storage in animals, while ATP and ADP are short-term energy storage.
