Currently, most organs that are harvested for transplant are transported from the donor to the recipient packed in ice and must be implanted within a matter of hours. How is organ culture an improvement on this transport method?Organs that are packed in ice can be damaged by frostbite during transit. 2 Cultured organs can be kept alive for several weeks before transplant. 3 Extra culture medium is easier and cheaper to transport than extra ice. 4 Organ cultures can be shipped as cargo rather than hand delivered.
Answers
The correct answer is (2) Cultured organs can be kept alive for several weeks before transplant.
Organ outside the body does not behaves in the same way as they do inside the body. These organs can be kept alive only when they are put into a culture solution, which can increase the shelf life of the organs by few weeks. It also reduces the chance of organ rejection. Cultured organs can be kept alive for several weeks before transplant.

Answer:
The lungs are made of a soft, elastic, spongy tissue.The large numbers of blood capillaries and rich blood supply gives the lungs their pink colour.
Final answer:
The lungs are pink because they are filled with oxygenated blood that has a pinkish hue due to the presence of oxygen-bound hemoglobin.
Explanation:
The lungs are made up of millions of tiny air sacs called alveoli, which are surrounded by blood vessels called capillaries. These capillaries contain oxygenated blood that has been pumped from the heart. When oxygen from the inhaled air enters the alveoli, it diffuses across the thin walls of the alveoli and into the capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be exhaled. The exchange of gases between the alveoli and the capillaries is facilitated by the thin walls and the large surface area of the alveoli.
The oxygenated blood in the capillaries gives the lungs a pinkish color. This is because oxygenated blood is bright red in color due to the presence of oxygen-bound hemoglobin, a protein in red blood cells that carries oxygen. As the oxygen-rich blood flows through the capillaries surrounding the alveoli, it imparts a pinkish hue to the lungs.

As we know that
P total = pO +pH +pN
so
P = P1 + P2 + P3
378 kPa= 212 kPa + 101 kPa + P(H2)
P(H2) = 65 kPa
partial pressure is 65
so correct option is A
hope it helps
Answer:
The correct answer is option A.
Explanation:
Total pressure of mixture = p = 378 kPa
Partial pressure of the oxygen gas =
Partial pressure of the hydrogen gas =
Partial pressure of the nitrogen gas =
As we know that total pressure is sum of partial pressures exerted by all the individual gases.
65 kPa the partial pressure exerted by nitrogen.

Hemoglobin is a crucial component of the circulatory system. It is a protein found in red blood cells that plays a central role in oxygen transportation. Therefore, the correct option is option 2.
The circulatory system, also known as the cardiovascular system, consists of the heart, blood vessels, and blood. Its primary function is to deliver oxygen, nutrients, hormones, and other essential substances to the body's tissues and organs.
In the context of the circulatory system, hemoglobin binds to oxygen in the lungs and carries it to the body's tissues, where it is released for cellular respiration. Additionally, hemoglobin helps transport carbon dioxide, a waste product of cellular metabolism, from the tissues back to the lungs, where it can be exhaled.
Therefore, hemoglobin's function and presence in red blood cells are closely associated with the circulatory system. Its role in facilitating oxygen and carbon dioxide exchange ensures the proper functioning and survival of cells and organs throughout the body.
Thus, the ideal selection is option 2.

Biomass is a good fuel alternative and has many advantages over the usage of coal. The most important is it is renewable and can be grown quickly. Option d is correct.
Biomass is an alternative fuel source. Biomass can be used to make biofuels and biogas. Coals are fossil fuel which means that they are formed from the fossilized remains mainly of trees and algae etc of the carboniferous period which was 286-360 mya. Which is why their presence on the earth is limited and they are soon bound to get exhausted.
These have lesser carbon dioxide emissions as compared to coal but they do have a carbon footprint. Additionally, while it is true that biomass can be used without being burnt through processes like anaerobic digestion and the resulting biogas/biofuel can be used to generate heat and electricity. This process can have a significant carbon footprint if not done properly.
Biomass can be used to generate biofuels that can be less polluting if utilized properly, However the fact that they are renewable and their production can be controlled is the most important.
Hence it can be concluded that biomass is better than coal because it can be grown quickly. Correct option is d.
