Answer:
Enhancer sequence.
Explanation:
Enhancers may be defined as the transcription factors that are used to enhance or increase the activity of the gene. Enhancers bind with the transcription factors to regulate and increase its expression.
The mutation in the enhancers decrease the transcription of of the other gene. These sequences lies far away from the transcription site but still known to increase the rate of transcription. Hence, the mutation has been done in the enhancer sequences.
Thus, the correct answer is option (b).
Carbon ,hydrogen ,and oxygen
I think the correct answer from the choices listed above is option C. The purpose of a controlled experiment is to examine whether one variable causes a change in another. A<span>n independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect.</span>
Answer:
(d). B-cells.
Explanation:
Adaptive immunity can be described as immunity which develops in response to exposure to a pathogen (or foreign molecule). throughout the life. It is divided into two types, humoral immunity and cell-mediated immunity.
Humoral immunity is mediated by B cells that secrete antibodies against particular antigens. These antibodies recognize and neutralize the antigens and activate cell-mediated immunity, which is mediated by T cells.
Thus, the correct answer is option (d).
