What is the source of energy that powers a hydroelectric power plant?

Biology
1 answer:
Verdich [7]3 years ago
4 0

Answer:  Given your four choices, the best/most correct one would be (c) the sunlight that evaporated water that eventually falls as rain and fills the reservoir. It is the potential energy stored in the reservoir water which is "released" as it is converted to kinetic energy (the movement of water which spins the hydroelectric generator turbine, etc.), but the absolute source of that original potential energy comes from the Sun's action to evaporate lake or ocean water which is returned to Earth as rain ... and it is this rainwater which ultimately fills the reservoir behind the hydroelectric power plant.

Like DNA, RNA contains four nitrogenous bases. Three of them are the same as those found in DNA. The one that is different is ca
densk [106]
The nitrogenous bases in DNA are adenine, guanine, thymine, and cytosine.
The nitrogenous bases in RNA are adenine, guanine, uracil, and cytosine.
So the base in RNA that is different than in DNA is uracil.

Hope this helps.

In humans, the ABO blood type is under the control of autosomal multiple alleles.Color blindness is a recessive X-linked trait.M
kifflom [539]

Answer: 1/4

Explanation:

Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.

Answer: The vulnerable embryo must be sheltered from desiccation and other environmental hazards. In both seedless and seed plants, the female gametophyte provides protection and nutrients to the embryo as it develops into the new generation of sporophyte.

Why would bourses and mountain goats have hooves
photoshop1234 [79]
Think of it like this.  Horses do a LOT of galloping, which is hard on the feet!  Hooves are a physical ADAPTATION, so that the horses won't experience pain on their journeys.  They're hard, so that the horses don't feel the ground nearly as much.  Now, mountain goats travel over rough terrain, with sharp rocks and steep inclines.  Again, it's really easy for them to get hurt strutting around the mountains, so they evolved hard hooves to protect their feet.

THe hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of __________ hemolysis on a blood agar
patriot [66]

The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.


The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.


The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.
