Answer:
water is denser than air and sound waves require a substance to travel through. when the substance is denser, the sound is amplified and carries farther. This excessive noise can be severely damaging to marine life's ears
Explanation:
Carbon dioxide<span> from the air goes into their leaves and thats how plants get carbon dioxide.</span>
Answer:
(C) Enzyme does not need to contact with substrate to assume its active form.
Explanation:
a) The activity of an enzyme can be increased upto certain temperature known as optimum temperature after that tepmerature will damage the enzyme.
b) The number of substrate molecule converted by one molecule of enzyme in one second is called its turn over rate, which may varry from 0.5-600000.
C) Enzymes does not need to contact with substrate to assume its active form. They just accelerate the reaction by lowering the activation energy. Enzyme binds to substrate through active stite and both changes structures slightly to best fit.(Induce fit model)
- Enzyme + Sbstrate → enzyme substrate complex→ Enzyme + Product
D) Some enzymes are inactive known as apoenzyme and they need a non-protein part such as coenzyme or cofactor to become active which is known as holoenzyme.
Unicellular - composed of only one cell.
multicellular - composed of multiple cells.
Answer:
each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana.
