what are the steps for creating hydroelectric power?
river water enters a dam through channels. the channels are connected to a transformer, which turns a generator, producing electricity. the water is then transported through turbines to wastewater canals.
river water stored in a reservoir flows down a channel in a dam, turning a turbine as it passes. the turbine is connected to a generator that produces electricity, and then the water continues downstream
river water stored in a reservoir flows through a turbine and into a channel in a dam. at the end of the channel, the water turns a generator, which produces electricity; then the water flows back upstream.
river water enters a dam through a generator. the movement of the water through a generator produces electricity. then the water flows out the dam through turbines into a reservoir.
Explanation:
Hydro-power plant captures the energy of falling water to produce electricity.
Hydroelectric power is produced as follows:
Water from the reservoir are channelized into tunnel where they turn the turbine or rotates the turbine with high power.Turbine is further connected to the generator. The rotating of turbines enables the production of current via generator.The produced current or electric power is then sent to the transformer which further distributes the power into various electrical lines according to demand.Hence the correct answer is option:'river water stored in a reservoir flows down a channel in a dam, turning a turbine as it passes. the turbine is connected to a generator that produces electricity, and then the water continues downstream'.

The side chain of ________ has a pka in the physiological ph range and is therefore often involved in proton transfer during enzymatic catalysis.
Final answer:
Histidine, with a pKa of around 7, is the amino acid whose side chain is most often involved in proton transfer during enzymatic catalysis due to its ability to exist in both protonated and deprotonated forms at physiological pH.
Explanation:
The side chain of histidine has a pKa in the physiological pH range and is therefore often involved in proton transfer during enzymatic catalysis. The pKa of the protonated histidine residue is approximately 7, which allows histidine to exist in both protonated and deprotonated forms within physiological conditions. This unique property makes it an ideal candidate to act as proton donor-acceptor groups in the active sites of enzymes. Histidine is commonly found in such roles in biochemical reactions because enzymes rely on the specific protonation states of amino acid residues to properly function.

As humans have converted prairies to pastures and farms, prairie dogs have lost 98 percent of their habitat. Prairie dogs are the only food source for ferrets. What is likely to happen to ferrets if prairies continue to dwindle?
A. Ferrets are likely to become overpopulated.
B. Ferrets are likely to become extinct.
C. Ferrets are likely to become plant eaters.
D. Ferrets are likely to become farm animals.
The correct answer is option B, that is, ferrets are likely to become extinct.
Ferrets are dependent completely on the prairie dogs for food and the construction of their homes. Thus, with the spontaneous loss of prairie dogs, the population of ferrets will also get a reduction. The black-foot ferret refers to a nocturnal stalker whose destiny is somewhat associated with that of the prairie dog. The ferrets feed on insects, mice, birds, ground squirrels, and it lives in the burrows built by prairie dogs, which are also its main prey.
However because of the generation of pastures and farms, and massive hunting, and poisonous campaigns against the prairie dogs, which are the prime food source for ferrets are also making the ferret population to decline.

Explain why it is necessary to incorporate buffers into media in whcih micororagnisms are grown
Final answer:
Buffers are necessary in media for growing microorganisms because they help maintain a stable pH. By incorporating buffers into the media, researchers can create an environment that supports the growth of microorganisms by providing optimal pH conditions for their survival and reproduction.
Explanation:
Buffers are necessary in media for growing microorganisms because they help maintain a stable pH. Microorganisms have specific pH requirements for growth, and fluctuations in pH can hinder their growth or even kill them. Buffers act as chemical stabilizers, minimizing changes in pH by absorbing excess hydrogen ions (H+) or hydroxide ions (OH-).
For example, in bacterial culture media, buffers like phosphate buffer or Tris buffer are added to maintain the pH within the optimal range for bacterial growth, typically around neutral pH.
By incorporating buffers into the media, researchers can create an environment that supports the growth of microorganisms by providing optimal pH conditions for their survival and reproduction.
A dihybrid cross is created from plants that are heterozygous for both round seeds and yellow seed color. What is the ratio of offspring that have round seeds and yellow seed color?
Answer:
1 : 1
Explanation:
According to the question, the parents are heterozygous (RrYy) and each would produce four types of gametes: RY, Ry, rY, ry.
Random mating between gametes of two parents gives phenotype ratio 9 round yellow: 3 round green : 3 wrinkled yellow : 1 wrinkled green.
Hence, ratio of round seeds ( 9 + 3 ) to yellow seeds color (9 + 3) is 12:12 = 1:1.

Hormones are secreted by exocrine glands directly into a body cavity or onto a body surface, rather than being transported by the blood. true or false?
Exocrine glands produce chemicals into ducts, which then deliver them to target tissues' surfaces. Therefore, the statement is true.
What are exocrine glands?A gland that secretes fluids, such as sweat, tears, saliva, milk, and digestive juices, through a duct or aperture that leads to the surface of the body. Sweat glands, lacrimal glands, salivary glands, mammary glands, and digestive glands in the stomach, pancreas, and intestines are all examples of exocrine glands. Exocrine glands are found throughout the body.
Both the liver and the pancreas are examples of exocrine and endocrine glands. Exocrine glands discharge compounds into the gastrointestinal system via ducts, such as bile and pancreatic juice. Endocrine glands, on the other hand, secrete substances directly into the bloodstream.

The element silicon is hard and brittle crystalline solid with a blue-gray metallic luster. Silicon is used as a semiconductor. Based on these properties as well as the location in the periodic table, we would classify silicon as a A) metal B) nonmetal C) metalloid D) rare Earth element
Answer: C) metalloid
Explanation: Metals are the elements which can easily lose electrons and are hard, ductile and possess luster. They are good conductors of heat and electricity.
Non metals are the elements which can easily gain electrons and are soft, non ductile and do not possess luster. They are insulators of heat and electricity.
Metalloids are the elements which have intermediate properties between those of metals and non metals and are called as semiconductors.
Thus Silicon is a metalloid.

Which statement describes the steps for chemical cycling in an old-growth forest? A) Trees create soil erosion, decay occurs, and trees take up soil nutrients.
B) Trees shade the ground, decay is slow, and trees take up soil nutrients.
C) Trees lose leaves, nutrients run off the soil, and soil erodes.
D) Trees create soil erosion, nutrients evaporate, and trees give off oxygen.
E) Trees take up soil nutrients, decay is slow, and trees give off oxygen.
Answer:
B) Trees shade the ground, decay is slow, and trees take up soil nutrients.
Explanation:
If you have ever been through a forest or a forest, you may have noticed that the soil in these environments is covered with organic matter. Leaves, branches, trees and even animals that end their natural life cycle end up disposing there, becoming great sources of nutrients after decomposition. Remember that in nature nothing is lost!
This process is known as “nutrient cycling,” which in other words means a continuous exchange of life-essential substances that takes place from soil to plants, and vice versa. In a dynamic interdependence, trees and plants return to the soil what has been "consumed" for their development, through the fall of leaves, fruits, and other things that will decompose, and thereafter, through the flow of energy, end up. getting back that extra little help.
This process occurs in the following steps: Trees shade the ground with falling leaves and fruits, decay is slow, and trees absorb soil nutrients from the decay.
