Vaccines help develop immunity by imitating an infection. This type of infection, however, does not cause illness, but it does cause the immune system to produce T-lymphocytes and antibodies. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity.
Answer:
The correct answer is option c. "frameshift mutations".
Explanation:
The reading frame of a gene is based on base-pair triplets, starting from the start codon until the ribosome encounters with the end codon. Base-pair additions and deletions are collectively referred to as frameshift mutations because they alter the reading frame of the gene. Base-pair additions and deletions break down the original sequence of the gene triplets, which alters the open reading frame and usually results in the production of non active proteins.
Answer:
B
Explanation:
The whole point of natural selection is for animals to compete to survive in that specific environment

Answer:
Changes in temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators can affect enzyme activity.
For example increasing substrate concentration increases the rate of reaction.
Explanation:
This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed.
Temperature is abiotic as it is not living :)
