Maintaining acidity- <span>In case the pH in the environment drops a lot (becomes very acidic), there is a flux of H ions from the cell's cytoplasm into the cell's vacuole thereby increasing acidity to required level and thus maintaining the </span><span>specific pH </span><span>in the cells internal environment as well.
Turgidity- </span><span>Vacuoles regulate the turgidity by regulating the amount of water inside the cell. </span>
cell has excessive water:<span> vacuole absorbs the water and then diffuses it out of the cell.</span>
cell lacks water<span>: water from the vacuole gets passed back into the cell thereby maintaining turgidity.

Answer:
As one of our most vital senses, the capacity to hear allows us to connect to the world for numerous very critical reasons. Most notably, hearing joins us to people enabling us to communicate in a manner that none of our different senses can accomplish.
Explanation:
Hearing allows us to connect with the world around us, it's beneficial to communicate with others, be able to listen for dangers, etc. Our ears can detect all sorts of noises, and all of these sounds have some sort of importance to us. Some noises can indicate danger, which is vital for survival. Hearing is also crucial for socialization; on average, a person will hear up to 70,000 words a day!
I hope this helped!! :)
The correct answer is this one: "A person who is infected with the herpes virus may develop a cold sore when the virus is in the lysogenic cycle." It best describes what a lysogenic cycle is. Lysogenic cycle is one of two cycles of viral reproduction.
The correct answer is C. Planets can move at a varying speed due to forces exerted in space.
Any moving object in space will travel in a straight line at the same speed forever, planets included. The planets would be moving in straight lines, but the sun’s gravity pulls them toward it, the force of gravity causes the moving planets to travel in roughly circular orbits around the sun.
(They have been circling the sun for billions of years because other forces have been too weak to change the orbits in any significant way)
Answer:
yes
Explanation:
An analysis of fossil traits indicates that Archaeopteryx is not a bird at all. ... Archaeopteryx seemed to confirm Darwin's theories and has since become a key piece of evidence for the origin of birds, the transitional fossils debate, and confirmation of evolution.
