Answer:
The correct statements are statement 3 and 4.
Explanation:
An alignment of three nucleotides within the RNA or DNA that assists in coding a specific amino acid or instructs the cell to either cease or begin the synthesis of protein is termed as a codon. A sum of 64 probable codons are found that comprise three of the four possible nucleotides, however, only 20 amino acids are present in the majority of the biological species.
The given third statement is true as there are some of the codons known as stop codons that plays an essential role in terminating the process of protein synthesis.
The given fourth statement is also true as codons known as stop codons are not identified by tRNAs, they are identified by ribosomes.
Twenty plus the four thousand and thirty eight equals a calculator and you need to use it.
Answer: TRUE
Explanation:
Sound waves enter the OUTER EAR and travel through a narrow way up to the eardrum, where it vibrates.
The vibrations are sent to the bones of the MIDDLE EAR where they are amplified, and passed to a structure called COCHLEA in the INNER EAR.
Finally, it reaches the sensory cells that passes it to the auditory nerve that transmit the sound to the brain as electrical signals (neural messages) for proper interpretation.
So, it is True because from OUTER EAR to MIDDLE EAR, to INNER EAR.
Answer:
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
Explanation:
the question is incomplete, but I annex the options and their explanation
When you compress the heart in this demo, why does the water leave the artery?
A It's like squeezing a sponge
B The arterial valve draws water from the ventricle.
C The atrioventricular valve has parachute-shaped fins to prevent water from escaping from the top.
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
the atrioventricular valve during the contraction process closes at the top, thus avoiding the leakage of the liquid and leaving the artery that opens due to the force exerted by the volume and force of the ventricle.
