Answer:
Explanation: The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases)
The advantageous proteins that build larger molecules help prolong life life. If there is better survival and reproduction, it is more likely to pass onto the next generation. If it continues to be advantageous, the sequence of them change to support the life of the current species.
Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing
Explanation:
All living organisms including humans are water-based systems, which implies that they rely intensely upon liquid equilibria, particularly acid-base equilibria. Hence, all the acid-base and pH ideas we have talked about so far are critical to the chemistry of organic or biological systems.
This is particularly significant for enzyme, which are proteins that go about as catalysts for all major biological reactions. Most enzymes just work inside a specific pH range. Because all natural cycles are subject to pH, cells and creatures must keep up a particular and consistent pH so as to keep their compounds in the ideal condition of protonation they have specific substances that counteract the acid and base to maintain pH.
for instance:
The pH of the Cytoplasm is maintained by the phosphate ion
The pH of the blood is regulated by the bicarbonate ion
Hail is formed when the water droplets freeze together in the cold upper region of the thundercloud. These lumps of ice are called hailstones. Most hailstones are between 5 mm and 15 cm in diameter and can be round or jagged. Hail stones are not frozen raindrops.
Factors that govern the ultimate size of hailstones are hail has strong storm clouds, especially strong heat, high liquid water content, large vertical range, large water droplets, and many cloud layers are formed by clouds below 0 ° C (32 ° F). This type of intense heat may also indicate the presence of a tornado.
