The independent variable in an experiment is the one that is deliberately modified or adjusted in order to observe its effects.
In this case, the varying amounts of caffeine administered to the dogs are the factor that changes—the control group receives no caffeine, the second group gets 10 mg of caffeine, while the third group gets 50 mg of caffeine each.
Thus, the amount of caffeine given to the dogs is the independent variable being altered.
In a protein, amino acids are interconnected through peptide bonds, which results in the formation of a lengthy chain. The bonding occurs via a biochemical reaction that eliminates a water molecule as it connects the amino group of one amino acid to the carboxyl group of another nearby amino acid.<span />
Answer:
Paraquat serves as a herbicide.
Explanation:
Coral bleaching wasn't induced by paraquat since it is a herbicide aimed at eliminating weeds, not algae. Coral hosts small algae essential for its coloration, hence applying paraquat wouldn't affect these algae, thus preventing coral bleaching. In contrast, if a different chemical that targets algae is used, it results in coral bleaching and turns the coral white.
Answer:
1128.
Explanation:
The phenotype for dominant tasters is 1482.
The phenotype for recessive tasters = 2400 – 1482 = 918.
Recessive phenotypes = 2400 – 1482 = 918.
The frequency of the recessive phenotype = q² = 918 / 2400 = 0.38.
The frequency of the recessive allele q = √0.38 = 0.62.
For the dominant allele frequency, p = 1-q = 1- 0.62 = 0.38.
The heterozygous frequency = 2pq = 2 × 0.38 × 0.62 = 0.47.
The number of heterozygous individuals within the population = 0.47 × 2400 = 1128.
Thus, the result is 1128.
