I would need some answer choices.
B. They use different nucleotide bases.
C. Transcription does not use DNA.
D. Only DNA replication happens in the nucleus.
Ans. (B). They use different nucleotide bases.
DNA replication involves synthesis of DNA molecules, while transcription is a process that involves synthesis of RNA molecules. In both processes, DNA acts as template and provides information for synthesis of new daughter DNA or RNA strand.
Process of replication and transcription differs from each other as each process uses different nucleotide bases. This is because, nucleotide bases in DNA include adenine, guanine, cytosine, and thymine, while in RNA uracil is present instead of thymine along with three similar bases.
Thus, the correct answer is option (B).
A complete circuit contains two parallel-connected devices and a generator for providing the electromotive force. The resistance of the first device is 12 ohms, the resistance of the second device is 4 ohms, and the voltage developed by the generator is 40 V. What is the magnitude of the current flowing through the first device?
A. 13.32 A
B. 3.33 A
C. 8 A
D. 10 A
Answer is 3.33 A
B. Positive feedback, because sweating can decrease body temperature
C. Negative feedback, because sweating can decrease body temperature
D. Negative feedback, because sweating can increase body temperature
could be a steroid hormone
does not pass through the cell membrane
binds to a receptor on the cell membrane
is this B?
