Capillaries; veins; arteries
Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.
Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.
Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.
Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.
Nonrenewable resources like oil, natural gas, and coal are efficient and economically viable due to established infrastructure. However, they have environmental impacts and are finite.
The question asks about the advantages of using nonrenewable resources. Nonrenewable resources such as oil, natural gas, and coal, have several advantages. One significant advantage of nonrenewable resources is their efficiency. These types of resources are often much more efficient in generating energy than renewable alternatives. For example, a small amount of coal or nuclear energy can produce substantially more energy than solar or wind power. Furthermore, nonrenewable resources are currently more economically viable. The infrastructure for extracting and using these resources is well established, making them cheaper to use in the short term as compared to renewable sources. However, we need to be aware of the environmental impact and the fact that these resources are finite and will eventually run out.

Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Answer:
The correct answer is "Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited".
Explanation:
Antibiotic resistance is a serious health issue that occurs when bacteria gains resistance against certain antibiotics, which reduces or eliminates the effectiveness of the treatments. The best explanation for this phenomenon is that some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited. This happens particularly when people do not take the full treatment or take treatment without diagnosis. In consequence, the populations of bacteria are not fully eliminated, increasing the probability of survival for bacteria that randomly mutates towards resisting the treatment.
