A. wind
B. coal
Explanation:
there are two fuels directly produces CO2 but is considered carbon neutral which are wind and coal
Answer: The correct answer is option E.
Explanation:
Digestions refers to the breaking down of food (larger molecules) into smaller absorb-able units.
Chemical digestion refers to digestion of food with the help of chemicals such enzymes, acid, and bile.
Enzymes are the main type of chemicals which hydrolysis (breaking down of compound with the help of water) the macro-molecules such as polysaccharides, polypeptides, et cetera into smaller and simpler units.
For example, amylase hydrolyse polysaccharides into smaller units such as maltose and glucose; trypsin, chymotrypsin, pepsin are enzymes which hydrolyze polypeptides into amino acids, nucleases are the enzymes which help in hydrolysis of nucleic acids, et cetera.
Bile and lipases help in emulsification of fats.
Thus, the correct answer is option E.
Cells make up the smallest bits of every living thing. Everything that contributes to a living thing being alive comes from cells, making it the fundamental part of life.
Answer:
If you lacked the enzyme to digest proteins, you may not absorb enough amino acids.
Explanation:
- Protein is one of the most important substance in our body that helps in repairing the tissues and muscles.
- Protein is made by the combination of amino acids.
- Out of 20, 11 types pf amino acids must be absorbed by our body through diet, only 9 types of amino acids is made by our body.
- So, if our body lacked the enzyme for protein digestion, we wont be able to absorb enough amino acids from the diet we consume.
Answer:
The exception is d) Inactivation of phosphodiesterase
Explanation:
In the presence of light:
a) The membrane potential of the photoreceptors is hyperpolarized, causing a reduction in the amount of neurotransmitter released by the photoreceptor terminal to the postsynaptic neurons
b) Sodium ions accumulate outside the plasma membrane and the receptor potential takes a form
of hyperpolarization 6. This change in membrane potential leads to the closure of calcium channels. The end result is a decrease in the secretion of the neurotransmitter glutamate by the photoreceptors
c) Visual transduction or phototransduction is the process by which a light photon generates a nervous response in the photoreceptors
d) As a consequence of phosphodiesterase activation, degradation of a molecule called cGMP (guanosine cyclic monophosphate) is stimulated
