Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)
Answer:
It is a common condition that includes overgrowth of atypical bacteria in the vagina
Explanation:
It is characterized by vaginal discharge that is when a fluid flows out from the vaginal opening with an abnormal odor or consistency and sometimes pain, the normal microflora of the female reproductive organs includes Gardenella, lactobacillus, Bacteroides, peptostreptococcus, fusobacterium , eubacterium, as well as a number of other types, some of the factors that may contribute to an abnormal increase of these bacteria or make them become unbalanced can be multiple or new sexual partners although some experts are skeptical about this; IUDs , recent antibiotic use, vaginal douching, and smoking. It is not dangerous but can cause discomfort symptoms.

The air begins to rise into the atmosphere. When air rises, it cools down and condenses into precipitation and clouds. This is why an approaching low pressure system means an increased chance for clouds, rain, or snow. It is called "low pressure" because as air rises, the air pressure is lower at the surface.
Events of the light-dependent reaction of photosynthesis starts with the absorption of sunlight and ends with ATP production.
<h3>Events of light-dependent reaction</h3>
- In the first step energy is absorbed from the sun and then water is broken down.
- Hydrogen ions of the water molecules are transported across the thylakoid membrane.
- NADPH is produced from NADP+.
- Hydrogen ions diffuse through the protein channel.
- ADP turns into ATP.
