The cell is taking in substances through membrane proteins, without any energy expenditure of its own. The substances naturally
Hitman42 [59]

The right answer is facilitated diffusion.

Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.

How are land, air, water and living things impacted by too much carbon dioxide?
choli [55]

Answer:

- In terrestrial environments: increasing CO2 levels cause an increased photosynthetic rate

- In aquatic environments: increasing CO2 levels cause an increase in water acidity  

- In both terrestrial and aquatic environments: increasing CO2 levels lead to an overall increase in the average temperature (global warming)

Explanation:

In terrestrial ecosystems, rising carbon dioxide (CO2) levels increase the rate of photosynthesis (since CO2 is one of the reactants in photosynthesis), thereby also increasing plant growth. Moreover, in aquatic ecosystems, rising CO2 concentrations increase the levels of this gas dissolved on the surface of the oceans. This increases the acidity of the oceans, thereby modifying habitats and food web structures. The increasing acidity of the oceans also reduces the amounts of carbonate, which difficult for aquatic species (e.g., corals) to form their shells/skeletons. Finally, CO2 is a greenhouse gas that contributes to the increase in the average temperature by absorbing solar radiation that would otherwise have been reflected by the Earth's surface, and this increase in the temperature negatively affects life in both terrestrial and aquatic environments.

Produces thick mucus to neutralize the normally acidic environment of the vagina
strojnjashka [21]

Answer:The seminal vesicles produce mucus to neutralize the acidic environment of the vagina.

Explanation:

The seminal vesicles is found in male reproductive system which produces mucus that is alkaline in order to protect the sperm from the acidic environment of the female vagina . This also contain sugar to nourish the sperm.

The vargina is the outer opening of female reproductive system that receives the sperm. It is acidic in nature because it discharge fluids that contain liquid, cells and bacteria that lubricate and protect it.

Vitamin C is best known for its role in preventing scurvy. It also is critical in the formation and maintenance of this protein
MrRissso [65]

Answer:

Collagen

Explanation:

Vitamic C or ascorbic acid acts as a cofactor in the process of collagen synthesis. It has been shown that lack of vitamin C leads to the impaired collagen synthesis. Beside that activity, vitamin C has many other funtions within organism:

  • antioxidant
  • cofactor in other enzymes
  • involved in wound healing (repair of tissue)
  • involved in the production of some neurotransmitters...
