<u>Answer:</u>
The correct answer option is D. Carry nerve impulses from the brain to skin, glands, and muscles
<u>Explanation:</u>
Motor neurons carry signals out of the Central Nervous System (CNS).
These motor neurons have long extensions called axons which spread from the CNS to the muscles that connect with the innervate.
The information from the brain to the muscles and other glands is sent in the form of electrical impulses via the spinal cord.
The answer is B. Precipitin Test.
Answer: The correct answer for the fill in the blank is- Transcription.
Transcription is a genetic process by which DNA ( deoxyribonucleic acid) is converted into mRNA ( messenger RNA) with the help of enzyme RNA polymerase.
During this process, the two strands of DNA are first separated so that the template DNA ( that is having polarity 3' to 5') is exposed.
Using the template strand, RNA polymerase adds the RNA nucleotides according to the Watson and Crick base pairing and thus mRNA transcript is assembled.
Gametes have a single copy of an allele for each gene while zygotes have two copies for each gene.
