Showing dominance over were ever they did that at
Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.
Answer:
This is a picture of an aminoacid chain
Explanation:
In an amino acid chain all amino acids ( for example GLY, VAL, or ARG) are linked by peptide bonds. Long chains, also called polymers, of amino acids are called proteins. The enlarged photo is an example of a structure of an amino acid. They have an amine (-NH2) and carboxyl (-COOH) functional group, along with a side chain (R group), specific to each amino acid.
Answer:
it is Basic brooooooo. No B NOT C AND NOT D. oNly A
Answer:
The above paragraphs describes that how salt- and fresh-water fish regulates their osmoregulation. Hence, the correct answer would be c. have adapted to deal with osmosis.
Osmosis is the process by which solvent's molecule move from region of low concentration (hypo-tonic) to the region of high concentration (hyper-tonic) through a semi-permeable membrane.
In sea-water fishes, the body fluids are hypo-tonic to the surrounding water and thus water is kept moving out of their gills. In order to prevent the excess water loss they need to drink water constantly and excrete concentrated urine.
In contrast, fresh-water fishes body fluids are hyper-tonic to surrounding water and hence, water keeps entering in their body through gills. So, in order to prevent excess dilution they absorb salt from surrounding with the help of gills and also their bodies reabsorb salt from urine.
