Carbohydrates often receive negative attention as the dieter's enemy. Yet the American Dietetic Association argues that they should be your main source of energy, accounting for 45 to 65 percent of your total daily calories. That's because carbs are your body's quickest fuel source, ultimately yielding the simple sugar glucose. Glucose fuels metabolic reactions throughout your body and is the only form of energy that your brain can use.
Capillarity helps life because plants use capillarity to move water from their roots to their leaves. Capillarity is a physical property of water, which can be described as the ability of water to move through very small conduct through molecular tension.This ability is very useful in case of plants, as water travels from roots to leaves.
Answer:
A. Rifampicin is an example of an enzyme inhibiting drug, since it acts on the bacterial RNA polymerase, preventing the transcription and synthesis of proteins, so the bacteria is not viable and a human disease is controlled.
B. The drugs have specificity by microorganisms —target organisms— which are also smaller and more susceptible, while their effect is minimal or null in human cells and are not poisonous for them.
Explanation:
Bacteria, viruses, parasites and pathogenic fungi are microorganisms capable of producing disease in humans. One of the ways to fight infectious diseases is the use of drugs called antibiotics, capable of interfering with the development of microorganisms.
<u>Antibiotics or antibacterials are capable of preventing the synthesis of the bacterial wall or its reproduction, intervening in the synthesis of proteins</u>. They do this through enzymatic inhibition of these processes.
- Rifampicin is a drug capable of coupling itself to one of the sub-units of the RNA polymerase enzyme, changing its configuration and preventing its affinity for its substrate, the bacterial DNA. Rifampicin thus prevents the synthesis of proteins necessary for the development of the bacterium, which dies and thus manages to control an infectious disease.
- Drugs such as antibiotics act on specific bacterial functions —their target organism— by affecting the functions that allow them to live that allow them to live, as if they were poisoned. These same <u>drugs have little or no effect on human cells when administered in appropriate doses</u>. The few effects that are observed in human cells are not sufficient to kill them, but they do produce effects or secondary reactions, usually called adverse effects.
Answer choices are:
A. Invalidate, because energy should not leave a closed system
B. Invalidate, because the amount of energy should stay constant
C. Validate, because an aquarium is an open system that loses and gains energy
D. Validate, because the amount of energy lost was replaced by matter.
The correct answer choice is:
C. Validate, because an aquarium is an open system that loses and gains energy.
Explanation:
As we know that, the law of conservation of energy is that the total amount of energy of an isolated system prevails to be constant, it is said to be maintained or conserved over time. This law means that energy can neither be created nor be destroyed; rather, it can only be converted or transferred from one form to another.
