A community is surrounded by forests. There is heavy rainfall, and most of the year it is very cloudy. It is located near two fa

st-flowing rivers. The people want to build a power plant that will not pollute. They are choosing between solar, biomass, or hydroelectric power. Write one to two sentences about each of these energy sources. Describe whether each energy source would meet their goals, and whether it is a good energy source for their area

Answer: Hydroelectric power will be the best energy source.

Explanation:

<u>Solar energy-</u> It refers to the energy that is directly derived from the sun, and are later used to convert into some kind of electrical or thermal energy. For example, solar panels.

<u>Biomass energy-</u> It is a type of energy that are directly obtained from the plants as well as organisms. This can be regenerated again and again. For example, bio-gas and food crops.

<u>Hydroelectric power-</u> It is a type of energy that is collected, from the rapid motion of water. A dam is needed to construct across a narrow river, which will store water as a reservoir. And this water, when allowed to flow then it initiates the movement of the turbines and due to this continuous motion of the turbines, electricity is generated.

Thus, the most efficient energy source for the given area is the hydroelectric energy, that fulfills the condition for setting up dams in the two rivers, which will generate a huge amount of electricity.

aivan3 [116]
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
                                   a = 1 m/s /  0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
                                  F = (80 g / 1000 g/kg) x (5 m/s²)
                                      = 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.

4. Discuss the concept of blended unity of mind and body, its implications for school physical activity programs, its implicatio
iragen [17]

Explanation:

This statement is correct because the concept of integrating body and mind in physical activity was responsible for the expansion of physical activity, in addition to activities that promote only the well-being of the body aesthetically, but as a set of activities responsible for improvement of health, intelligence, emotional, creativity, as well as an instrument of social integration. The practice of physical activity releases endorphins in the brain, which is a natural substance produced by the brain that is associated with well-being, mood and joy, and this effect occurs during and after physical activity.

netineya [11]

Answer:

43 monosaccharides will be joined together to make the complex carbohydrate.

Explanation:

The complex carbohydrates are synthesized by the joining of monosaccharide residues by glycosidic linkages.One glycosidic linkage joins two monosaccharide residues by the elimination of one molecule of water.

  In other words it can be said that elimination of one water molecule joins two monosaccharides.By the same way elimination of 42 molecules of water will result in the joining of 43 monosaccaride residues.

What are similarities and differences between the organization and structure of DNA in bacterial cells and in human cells?
Ilia_Sergeevich [38]
Both human and bacteria cells contain DNA and both have a outer membrane that controls how materials come into and leave the cell.

Predominantly multicellular not in bacteria but in human body

*Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body..

*DNA occurs in a circular form* in bacteria only..

* Ribosomes size in bacteria 70s and in human body 80s

*Capable of growth at temperatures greater than 80 C only in bacteria

*His tone proteins present in cell only in human body cells

* Operons present in DNA only in bacteria..
