Answer:
2. tRNAQ binds the A site of the ribosome.
1. The polypeptide is transferred to tRNAQ.
4. The ribosome shifts, with tRNAQ still bound.
3. tRNAQ binds the P site of the ribosome.
4. The ribosome shifts, with tRNAQ still bound.
5. tRNAQ binds the E site of the ribosome.
Explanation:
tRNAQ first lands on the A site of the ribosome. It carries an amino acid according to the exposed codon on A site. A bond is formed between the amino acid of A and P site such that the polypeptide is transferred to tRNAQ. The ribosome shifts now and tRNA Q moves to P site from A site while still bound to mRNA. Another tRNA enters the A site and the above process is repeated which finally transfers the polypeptide chain from tRNAQ to new tRNA. tRNAQ has no attached polypeptide now and is ready to leave the translation complex. The ribosome shifts again with the tRNAQ still bound to mRNA. tRNAQ enters the E site from P site and finally leaves the translation complex by exiting the E site.
It all depends on the species, some lose all of their leaves for part of the year while others lose their leaves before the next growing season, retaining some during winter or dry periods.
Answer:
The options
A) "Efficient heart function requires that the ventricles do not retain any blood at the end of the cardiac cycle."
B) "Recall that the heart sounds that we listen to as part of our assessments are the sounds of the myocardium contracting."
C) "The diastolic phase is characterized by relaxation of ventricles and their filling with blood."
D) "Aortic pressure will exceed ventricular pressure during systole."
The CORRECT ANSWER IS C)
C) "The diastolic phase is characterized by relaxation of ventricles and their filling with blood."
Explanation:
Diastole is connected with ventricular filling and relaxation. Cardiac production is not 100% or in proximity to been 100% with every cardiac cycle, as the heart sounds are linked with valve closure. Ventricular pressure surpasses that of the aorta in the course of the systole.
