To describe:
The advantage of four-chambered heart with its two separate pumps.
Introduction:
The heart pumps blood throughout the body and provides transport of oxygen and the other gases. The number of chambers present in the heart defines the three major heart types; two-chambered, three-chambered, and four-chambered heart.

Explanation of Solution
The four-chambered heart has evolved from the three-chambered heart of amphibians and the two-chambered heart of fishes. The four-chambered heart contains two pumps (atria and ventricle) and two circulatory systems (pulmonary and systematic system), and have the following advantages over three and two-chambered heart;
Efficiency: The four-chambered heart separates the oxygenated and deoxygenated blood from mixing. Superior chambers receive the blood and pump it to the inferior chambers. The efficiency of the heart is increased by the separation of blood which is received and pumped out from the heart.
Pressure: The four-chambered heart has a double circulatory system which contains blood under high pressure, which allows transportation of nutrients and gases at a rapid rate.
Power: In association with the respiratory and circulatory system, a four-chambered heart provides a rich supply of oxygen and nutrients to the tissues in the body, which is responsible for energy generation in the body.
It also helps in maintaining higher
Efficiency, rapid transportation, and energy generation are the main advantage of the four-chambered heart with two pumps.

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward

First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together.
