How are solar cells different from most other power sources?

Answers

Answer: they just are and because they use the sun

Explanation: not sure at all tho

Solar cells are different from most other power sources because they utilize the sun's energy, have a smaller environmental impact, are scalable, becoming more cost-effective, and require minimal maintenance. These factors contribute to the growing popularity and importance of solar power as a sustainable and reliable source of electricity.

Solar cells, also known as photovoltaic cells, are different from most other power sources in several ways. Here are the key differences:

1. Energy Source: Solar cells convert sunlight directly into electricity, making use of the photovoltaic effect. This means that they rely on the abundant energy from the sun, which is a renewable and sustainable source. In contrast, most other power sources, such as fossil fuels or nuclear power, rely on limited resources that can be depleted over time.

2. Environmental Impact: Solar cells have a much smaller environmental footprint compared to most other power sources. Fossil fuel-based power plants emit greenhouse gases and contribute to air pollution, which leads to climate change and other environmental issues. Solar cells generate electricity without any emissions, making them a cleaner and more environmentally friendly option.

3. Scalability: Solar cells can be easily scaled up or down to meet different energy needs. They can be installed on rooftops, in large solar farms, or even integrated into portable devices. This flexibility allows solar power to be used in various applications, from powering homes and businesses to providing electricity in remote areas. In contrast, many traditional power sources require large infrastructure and are less adaptable to different settings.

4. Cost: While the initial cost of installing solar panels may be higher compared to traditional power sources, solar energy has become increasingly affordable in recent years. The cost of solar cells has significantly decreased due to advancements in technology and increased production. Additionally, solar energy has the potential for long-term cost savings since sunlight is free and abundant, reducing reliance on expensive fuel sources.

5. Maintenance: Solar cells require minimal maintenance compared to most other power sources. Once installed, solar panels typically require only occasional cleaning and inspections. In contrast, fossil fuel power plants require regular maintenance and are prone to breakdowns, which can lead to power outages and disruptions.

Two squirrel populations are said to have very little gene flow. What will most likely
happen to these populations?
a
The populations will evolve separately from each other.
b
The populations will evolve at the same rate.
c
Both populations will develop the same ratio of alleles.
d
There will be an increase in diversity within both populations.​

Answers

Answer:

The correct answer is option a. "The populations will evolve separately from each other".

Explanation:

Two squirrel populations that have very little gene flow will not share their genetic adaptations to survive the changing environmental conditions that they can face. Therefore, it is very likely that the two populations will evolve separately from each other. This contrasts with species that evolve collectively since they share their genetic adaptions due to a high gene flow among them.

What process does the purple arrow indicate? CarbonCycleAQ1 A. Respiration. B. Photosynthesis. C. Combustion. D. Decomposition.

Answers

Answer:

The correct answer is option B. "Photosynthesis".

Explanation:

Photosynthesis is the process at which land plants produce energy from carbon dioxide in the presence of sunlight. This process is essential for plants, but also for all other living beings because photosynthesis allow plants to produce their own food (while other living beings feed from plants), as well as the production of oxygen as byproduct. The purple arrow indicate the absorption of atmospheric carbon dioxide by land plants, which belongs to the photosynthesis process. I attached the missing picture.

Answer:

B. Photosynthesis

Explanation:

The process in purple arrow indicate the process of photosynthesis.

Photosynthesis is carried out by green plants and it involves the use of carbon dioxide and water in the presence of light to synthesize glucose. The light energy needed for the reaction is absorbed by the green component of plants, the chlorophyll.

The process is summarized by the equation:

[tex]6CO_2 + 6H_20 + (energy) --> C_6H_{12}O_6 + 6O_2[/tex]

Hence, the purple arrow represents the diffusion of carbon dioxide into the vegetation as a precursor for photosynthesis.

SOMEONE ANSWER this PLEASE I needed in less than 10 MINUTES.​

Answers

Answer:

B

Explanation:

Based on the passage, if human cells had a lot of chlorophyll, they would most likely be green, hence option B is correct.

 

What is the importance of chlorophyll?

In a plant, chlorophyll's function is to absorb light, often sunlight. Two types of energy-storing molecules receive the light energy that is absorbed.

The plant uses its stored energy to turn water and carbon dioxide from the air into glucose, a form of sugar, through photosynthesis.

The thylakoid membrane contains the green pigment chlorophyll, and the region between it and the chloroplast membranes is known as the stroma.

Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.

Therefore, chlorophyll provides green color to the plants.

B)Large molecules, such as glucose, use membrane proteins to cross the cell

membrane.

C)Osmosis is an active transport process that moves water against the

concentration gradient.

D)

Charged molecules, such as Cat, Na, and K* cannot diffuse directly across

the cell membrane and must use membrane proteins.

Answers

Answer:

The correct answer is option C) "Osmosis is an active transport process that moves water against the concentration gradient".

Explanation:

Osmosis is defined as a passive transport process, because it does not require energy to occur. Osmosis takes place when water moves from an area of high concentration to an area of low concentration. Therefore, it is false to affirm that osmosis is an active transport where water moves against its concentration gradient, actually the opposite is true about osmosis.

What is the difference between the Domains Eukarya and Bacteria

Answers

Bacteria do not contain a nucleus and Domains Eukarya do contain a nucleus

Final answer:

The primary difference between the domains Eukarya and Bacteria is that Eukarya contains organisms with cells that have nuclei and other organelles, while Bacteria consists of single-celled prokaryotes without nuclei, with genetic material that is not membrane-bound.

Explanation:

The domain Eukarya is one of the three domains of life, alongside Bacteria and Archaea, in the classification system of organisms. The chief distinction between the domain Eukarya and domain Bacteria lies in cellular organization. Organisms within the domain Eukarya possess cells with nuclei, where their genetic material is encased in a membrane-bound nucleus, and they also contain other membrane-bound organelles. These organisms range from unicellular protists to multicellular fungi, plants, and animals. In contrast, the domain Bacteria comprises entirely of single-celled prokaryotic organisms that do not have a nucleus. Instead, their genetic material freely floats within the cell, unbounded by a membrane. Bacteria have diverse lifestyles and can be found in nearly every environment on Earth, including some that are inhospitable to most other life forms. Additionally, bacterial cell walls are characterized by the presence of the polysaccharide peptidoglycan. To summarize, the significant differences between the domains Eukarya and Bacteria include cellular structure (presence or absence of a nucleus), complexity (single-celled vs multicellular), and the composition of their cell walls. The addition of the domain taxon is indicative of the constant evolution of scientific understanding, reflecting the fundamental differences discovered between various forms of life.

The carbon cycle is a cycle among the carbon reservoirs.What is a carbon reservoir and what are some examples?

Answers

Answer:

Explanation:

The reservoirs are the atmosphere, the terrestrial biosphere (which usually includes freshwater systems and non-living organic material, such as soil carbon), the oceans (which includes dissolved inorganic carbon and living and non-living marine biota), and the sediments (which includes fossil fuels)

A carbon reservoir is a location or a natural process that stores or releases carbon. The carbon cycle describes the movement of carbon between these reservoirs over time.

What is carbon cycle?

The carbon cycle is the exchange of carbon between the Earth's atmosphere, land, ocean, and living organisms.

Carbon can be stored in a variety of reservoirs, such as:

The atmosphere is the world's largest carbon reservoir, containing carbon in the form of carbon dioxide (CO2).

The ocean is a major carbon reservoir because marine organisms use dissolved CO2 in the water during photosynthesis.

Soil: Because it contains organic matter from dead plant and animal material, soil is a significant carbon reservoir.

Fossil fuels: Carbon reservoirs such as coal, oil, and natural gas formed over millions of years from the remains of dead organisms.

Thus, these are the carbon reservoirs.

Matter is everything which satisfies  two conditions  such as mass and volume.  For example atoms.

In solids, the particles are close to each other, strong attractive forces. It has a definite volume and  shape.

Solids have different properties like elasticity, plasticity, rigidity, malleability, ductility, conductivity, it can be amorphous and crystalline.

Liquid is is link between solids and gases, Intermolecular forces are stronger than gases but weaker to solids.

They have high density, flowability, conductivity, viscosity, refractive index, surface tension.

Gases have no shape and volume, the velocity is much higher relative to liquids and gases.

Gas have lowest density, pressure, temperature, viscosity and it can liquefy under compression called as condensation.

Plasma does not exist in normal condition. when gas is heated to extreme temperature, plasma formed. It is also called as ionization of the gas.
