Answer: 8hrs
Explanation:
G1 phase is the intermediate phase between the end if cell division and the beginning of DNA replication.
Thus to get the duration of the G1 phase = 1/3 × 24hrs = 8hrs
OPTIONS:
a) Blood delivers calcium and phosphate ions that are needed for building bone extracellular matrix.
b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.
c) Blood carries newly absorbed nutrients and water to the liver.
d) Blood circulates cells and chemicals that carry out immune functions.
e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged
Answer:
b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.
Explanation:
Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.
Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs.

Answer:
The type of regulation of gene expression that would have the greatest chance of success is Posttranslational control (E).
Explanation:
The defect is found on the structure of the protein, this means that the process of formation of the protein and the codons responsible for each amino acid in the protein is in correct order, this set the transcriptional and translational process aside as being correct.
Therefore, the problem lies in the formation of secondary or tertiary structure of the protein which requires a good number of proteins also, wherein lies tha main problem in the cell membrane protein. Thus the regulation of the posttranslational process and correction of the proteins needed at this stage will give the best chance of success.
