Most bacteria are eventually able to change their genetic makeup in order to become resistant to antibiotics. Therefore, the antibiotics no longer have an effect on the infections.
Narcotic drugs are analgesic that exert a depressing action on the central nervous system.
Hope this helps!
Answer: osmosis
Explanation: osmosis is the movement of the water molecules from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
This movement occurs until the concentration on both sides is on equilibrium.
Semi permeable membrane allows the movement of water only but not the solute.
In this case,water moves from region A to region B.
Answer:
<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>
Explanation:
The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.
Precipitation would help distribute water all over the earth's surface, which gives animals and humans a source for water. Precipitation also helps plants grow which in turn provides humans with fresh air. Evaporation also benefits the different living organisms on earth by purifying the water. When water evaporates, pollutants are filtered and left behind , which makes it cleaner during precipitation.
