Answer:
Natural selection is the process of which forms of life having traits that better enable them to adapt to specific environmental pressures, such as predators, changes in climate, or even competition for food or mates. As the species will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations.
Answer:
diagram is weird and unrealistic but B is the only reasonable answer.
Explanation:
B only makes sense - everything else is unreasonable. Proteins don't become enzymes since enzymes are already proteins, there are no proteins, carbohydrates, or glucose molecules in the image.
Answer 1:
The mutation shown is point mutation.
A point mutation can be described as a type of mutation in which only a single nucleotide of a sequence is either:
The addition of the single nucleotide will cause the entire open reading frame to be changed. The amino acid sequence will change entirely from the position where the insertion mutation occurs. This is because the code for making amino acids works on a three base pattern. The reading of the three bases will be altered completely by the addition of just a single nucleotide.
Answer 2:
No, the resulting protein will not be altered.
The genetic code occurs in a linear sequence with triplet format. The change in a single base will cause the wrong amino acids to be formed. However, if the different code is common for the same amino acid then there will be no effect on the amino acid being formed.
<em>For example, the code GUA makes the amino acid Valine. If a mutation occurs and the code becomes GUU instead of GUA, then the resulting amino acid formed will also be Valine. Hence, there will be no alternation in the formation of the protein.</em>
Answer 3:
Melanoma cancer is the type of skin cancer which is associated with cancer from sun light. It is mainly caused due to the harmful ultraviolet rays which act as a mutagen.
<em>The mutations might keep coming back because although the growth have been removed, the other skin cells of the body might still have the mutation in them. As a result, growth will be seen again in the skin cells which might occur again and again. </em>
