Answer:
3 The mRNA was not bound to by a ribosome 4 tRNA: anticodon matching 5 switching from normal nucleotide for an abnormal one .
Explanation:
3 If the mRNA is not bound to the ribosome then this do not prevent the mRNA from being transported to the Endplasmic reticulum in the cytoplasm.This because binding of ribosome to the mRNA is essential after the mRNA has reached the cytoplasm to initiate the process of protein synthesis.
4 tRNA contains Anticodons that interact with the codon present in the mRNA to bring an amino acid specific for that codon to the A site of ribosome.
5 Mutation at the 3" nucleotide reading frame switch a normal nucleotide for an abnormal one.
Using the theories of nervous system, we got it is true that inhibition of the sympathetic nervous system inhibits urination primarily by inhibiting the detrusor muscle.
Nervous system involves large number of mechanisms at the same time.
The parasympathetic nervous system stimulates the detrusor muscles to contract, causing the person to urinate. This sympathetic nervous system stimulates the contraction of the internal urethral sphincter, causing the person to hold the urine. Somatic efferent neurons stimulate contraction of the external urethral sphincter, which is the skeletal muscle.
Hence, inhibition of the sympathetic nervous system inhibits urination primarily by inhibiting the detrusor muscle is true.

You can infer that the birds once had a common ancestor but became separated. Mutations in copying their genes stacked and caused changes in the beaks so the birds could be more well off or better adapted in their new environment.
Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
The answer is C. They haven’t gone through physically restorative sleep and therefore may need to go to the doctor, especially if it happens often.
