Answer:
your body produces melatonin it is to help you fall asleep
Explanation:
Answer: Option B) No, even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
Explanation:
Since the triplet codon ACG codes for the amino acid threonine, so also ACA codes for threonine, the single base change of Guanine (in ACG) to Adenine (ACA) is insignificant due to the degeneracy of the genetic code.
Thus, the sequence still codes for the same amino acid, so no change in phenotype will occur
Answer:
Natural selection causes change in allele frequencies within a population.
So option A is correct one.
Explanation:
Natural selection generally work on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
Answer:
Adaptations and selective breeding, if that is a choice for you.
Explanation:
Answer:
The question as the options lacking but based on the question we can infer the ANSWER
Based on the results of the experiment we can best say that urea will disrupt the function of the certain enzyme and that when the urea is removed the enzyme regained its function.
Explanation:
Denaturation is the term used to describe urea effect on the enzymes as it inactivates it by affecting it's secondary and tertiary function. In the process it’s 3D structural conformation is altered.
