Input x 100 (%)
If a power plant uses 100 units of
energy to create electricity and the
output is 5 units, where does the
95% of the energy input go?
A. lost as heat
B. lost as gas
C. escapes the system as potential energy

Answers

Answer 1
I looked it up and the answer is A because lots of electricity is lost as heat through conductors. i also found stuff for the other answers but this seemed the most accurate and credible.
Answer 2

If a power plant uses 100 units of energy to create electricity and the output is 5 units, 95% of the energy input goes as lost as heat.

Could you ever create a machine where 100% of the input energy would turn into output energy?

No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance.

How do you calculate the energy efficiency of a power plant?

To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.

Identify the biotic factors in the environment shown. Check all that apply.

1) people

2) grass

3) rocks in the mountains

4) nylon tent

5) wooden kayak

Answer:

1) people

2) grass

Explanation:

The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements. Biotic factors are all the living components in the ecosystem.  

Biotic and abiotic factors influence the survival and reproduction of living beings. They are related and in constant interaction. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.  

Every abiotic component influence organisms and their survival and reproductive rates.

A few examples of the abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.

Examples of biotic factors are plants, animals, insects, microorganisms, etc.

-------------------------------------------------------------------------------------------------------------

The biotic factors of the provided list are:

People, which is a group of individuals composed of cells -which is the basic unit of life-. They grow, reproduce and survive. Grass, as one or many species of vegetables that are also multicellular. They grow, reproduce, and survive.

The abiotic factors are:

Rocks, which are non-living things composed mainly of mineralsTent, which is also a non-living thing, is artificially made by humans.

In my opinion, the wooden kayak is a gray zone, meaning that it might be confusing. A kayak is an abiotic element with no life and is built by men. But it is constructed of wood. The wood originates in trees that are living beings, they are composed of cells, and they used to be alive. However, when talking about the kayak wood, we are referring to dead tissue. It is not alive anymore. Its cells are dead so, their whole system is not working. It is now composed of minerals and other elements with no life, and it has been modified and processed to build the kayak.

So my opinion is that the wooden kayak is an abiotic factor.

Answers

Answer:

Read explanation

Explanation:

Surface C exerts the least amount of friction on the box. Evidence that proofs this claim is that the length of time it took the box to stop is greatest compared to surfaces A and B. The box and the amount of force added is the same for each surface test. It would take the box less time to come to a stop the more friction there is upon the surface.  Surface A having the quickest stop time meaning it has the most friction and C having the most time showing that it has the least amount of friction. In conclusion, surface C exterts the least amount of friction on the box.

Choose the correct climate for: grasslands near the equator



a low latitude climates


b dry mid-latitude climates


c humid continental climate

Answers

The most appropriate climate for grasslands near the equator would be a low latitude climate. This region has a tropical wet-dry climate that has a prolonged dry season. During the dry season, the land becomes parched and the vegetation dies out.

However, the grasses have extensive root systems, enabling them to survive long periods of drought. During the wet season, the grasses become green and grow quite fast to feed the herbivores that live in this region. This climate is suitable for the grasslands near the equator because the temperatures are high and the rainfall is irregular.

Therefore, the grasslands experience both a wet and dry season each year, which affects the flora and fauna. The low-latitude climate is characterized by high temperatures and high rainfall. This type of climate is found in areas near the equator, where the sun's rays are almost perpendicular to the earth's surface, resulting in high temperatures.

The grasslands are subject to strong sunlight, but they also require a certain amount of rainfall to survive. The grasslands near the equator, therefore, require an environment that is humid and receives regular rainfall but still experiences dry periods that are long enough to allow the grasses to thrive.

question 62 80) a reduction in the amount of nadp available in plant cells in the light will ultimately result in a) an increase in the rate of the calvin cycle. b) a decrease in the rate of linear electron flow. c) a decrease in the rate of cyclic electron flow. d) an increase in the rate of oxygen production.

Answers

A reduction in the amount of NADP available in plant cells in the light will ultimately result in a decrease in the rate of linear electron flow. This is because the linear electron flow depends on the availability of NADPH which is the reduced form of NADP (nicotinamide adenine dinucleotide phosphate) and ATP that are produced during photosynthesis so the correct answer is option (B).

NADPH plays a crucial role in the Calvin cycle by providing energy in the form of high-energy electrons that are used in carbon fixation. The electrons are transferred from NADPH to CO2 to form carbohydrates, and in the process, NADPH is oxidized to NADP. In the absence of NADPH, the Calvin cycle would not be able to proceed at a normal rate. ATP is also required by the Calvin cycle to provide the energy required to power the various enzymatic reactions that take place during carbon fixation.In the presence of light, photosynthesis occurs in two stages: the light-dependent reactions and the light-independent reactions.

The light-dependent reactions occur in the thylakoid membranes of chloroplasts and involve the conversion of light energy into chemical energy in the form of ATP and NADPH. Linear electron flow is the primary pathway that produces ATP and NADPH during photosynthesis. It involves the transfer of electrons from water to photosystem II, through the cytochrome b6f complex, and on to photosystem I before finally being transferred to NADP+. Cyclic electron flow also occurs in photosynthesis but produces only ATP. In cyclic electron flow, the electrons are recycled back to the cytochrome b6f complex instead of being transferred to NADP+.

Therefore, a reduction in the amount of NADP available in plant cells in the light will ultimately result in a decrease in the rate of linear electron flow.

If haploid for an organism is 30 individual chromosomes, how many individual chromosomes would a somatic cell for this organism possess?
a. 15
b. 10
c. 90
d. 60
e. 30

Answers

A somatic cell for this organism would possess 60 individual chromosomes. Therefore, the correct answer is d. 60.

If the haploid number of chromosomes for an organism is 30, it means that each gamete (sex cell) of that organism contains 30 individual chromosomes. Gametes are haploid cells, meaning they only have one set of chromosomes.

In contrast, somatic cells are diploid cells, meaning they contain two sets of chromosomes. The diploid number of chromosomes is typically denoted as 2n. Therefore, to determine the number of individual chromosomes in a somatic cell, we multiply the haploid number (n) by 2.

For the given organism with a haploid number of 30 individual chromosomes, a somatic cell would possess:

2n = 2 * 30 = 60 individual chromosomes.
