The reason due to which evolution of multicellular organisms led to the development of the circulatory system. Introduction: Because they consist of several cells, multicellular organisms are structurally complex beings. They can be seen with the unaided eye. They have unique organ systems and organs. Since they are eukaryotes, they have structures that are bound to membranes. The division of work is visible in their cells.

Expert Solution & Answer

Explanation of Solution

Blood arteries that transport blood away from and toward the heart make up the circulatory system. Blood is transported from the heart by arteries and returned through veins. Oxygen, nutrients, and hormones are delivered to cells by the circulatory system, which also eliminates wastes like carbon dioxide.

In multicellular organisms, the nutrients, oxygen, and minerals should be transported to each cell and the metabolic wastes and toxins should be removed from each cell. To enable these transports, the circulatory system evolved in multicellular organisms. For instance, the blood carries oxygen and nutrients that are taken up by the cells, and the wastes like carbon dioxide are released in the blood. This blood is filtered into the kidneys and the wastes are removed from the body.

Conclusion

The circulatory system evolved in eukaryotes to transport oxygen and nutrients to the cells and remove metabolic wastes from the cells.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin

Explanation of Solution

Blood arteries that transport blood away from and toward the heart make up the circulatory system. Blood is transported from the heart by arteries and returned through veins. Oxygen, nutrients, and hormones are delivered to cells by the circulatory system, which also eliminates wastes like carbon dioxide.

In multicellular organisms, the nutrients, oxygen, and minerals should be transported to each cell and the metabolic wastes and toxins should be removed from each cell. To enable these transports, the circulatory system evolved in multicellular organisms. For instance, the blood carries oxygen and nutrients that are taken up by the cells, and the wastes like carbon dioxide are released in the blood. This blood is filtered into the kidneys and the wastes are removed from the body.

The circulatory system evolved in eukaryotes to transport oxygen and nutrients to the cells and remove metabolic wastes from the cells.
