C) If we spray insecticide, only those who are resistant to the insecticide will survive.
That is what the bottleneck effect entails - a sharp reduction in the population and the survival of only a few.
Answer:
Disaccharides, polysaccharides, glucose, fructose, galactose
Explanation:
This is a very broad question making it very difficult to answer. Glucose, fructose, and galactose are all types of monosaccharides (simple sugars), while disaccharides and polysaccharides (complex sugars) contain multiple monosaccharides.
Answer:
<u>A. Compound A</u>
Explanation:
Enzymes are specialized, folded proteins that act as biological catalysts- they speed up the rate of certain chemical reactions in biological systems. Enzymes bind to substrates like compound A to their active site, where they facilitate the modification of molecular strutures, creating new compounds.
Inhibitors like compound C can prevent enzyme-substrate binding activity; the chemical reactions do not occur because the substrates cannot gain access to the active site. Because enzymes show specificity, binding only to certain substrates, other molecules cannot be catalysed by the enzyme.
Here, the amount of Compound A, which is produced via the conversion of R, is increased due to the reaction inhibition- its conversion to B and D is not mediated by X, the inhibited enzyme. While conversion may still occur slowly, without its catalyst, more of the compound is being converted from R to A than A to B and D.
T<u>he concentration of A is least likely to decrease.</u>
Answer: The statement is false
Explanation: A codon consists of three nucleotides instead of four. Codons are triplets of nucleotides on an mRNA molecule that code for specific amino acids. Each amino acids are specified by at least one codon. Some amino acids are specified by one codon, some are specified by two or more codons. The phenomenon whereby more than one codon specifies one amino acid is known as the degeneracy of the codons.
