First of all, I better get brainliest answer for all of this trouble.

Fossil Fuels
Fossil fuels are nonrenewable resources. They come from deposits of decomposed organic matter from millions of years ago, and are highly combustible. Common examples of fossil fuels that we use every day include coal, crude oil, and natural gasses.

Nuclear Energy
Nuclear energy comes from nuclear power plants, which produce energy through a process called fission. Fission creates heat, which heats water to create steam, which spins turbines (like windmills or water wheels) to produce energy. Fission is produced by splitting uranium atoms.

Biomass
Biomass is the total mass of organisms in a given area or environment. This is a renewable source of energy. Biomass energy comes from burning the organisms, which get their energy from the sun through photosynthesis. Burning the biomass releases energy in a chemical reaction.

Hydropower
Hydropower (hydroelectric power) uses a dam to store water in a reservoir, which releases water through a turbine which spins the turbine in order to produce energy (similar to the nuclear energy process and wind power).

Solar Energy
Solar power directly harvests energy from sunlight. This energy is harvested using photovoltaics (PV), and this is a renewable energy source. Mirrors can be used to focus solar light, and PV are used to convert sunlight into electric current.

Geothermal Energy
Geothermal energy is a clean and sustainable source of power that comes from the Earth's own heat. From shallow ground, the heat is accessed from hot water or hot rocks in order to produce this energy.

Wind Energy
Wind turbines are used to produce clean, renewable sources of energy. Like nuclear power or hydroelectric power, windmills are engineered to catch any amount or direction of wind in order to spin a turbine to produce electricity.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

Based on the observations provided, what is the relationship of current diabetes medication use and the use of extract from ginko biloba? a) the anti-inflammatory properties of ginko biloba extract are beneficial in treating t2d separate from the benefits of other therapies. b) the overall abundance of ginko biloba makes this extract an attractive joint therapy for existing medications that are used to treat t2d. c) the side effects of t2d medications have resulted in the need for different therapies to treat t2d like the use of ginko biloba extract. d) clinical outcomes from the use of current t2d medications may be improved through the use of cost-effective ginko biloba extract treatment. e) previous studies with ginko biloba and current t2d medications do not support the use of these treatments as effective against t2d in patients.
