Explanation:
The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work
Answer:
2754.33% increase
Explanation:
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%
Percent change = 2754.33% increase
Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.
The total increase is 2754.33% increase
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [tex]\frac{[(72500 MW - 2540 MW)}{ 2540 MW }* 100%[/tex]
After solving the equation the percent change = 2754.33% increase.

One of the concerns about rising CO2 levels ocean water is the negative effect on certain types of marine life, such as oysters and clams. Does your experiment show a negative effect? Explain your answer.
Answer:
see below :)
Explanation:
For many years sea life such as oysters and clams have been acostumed to the temperature of the water. Rising levels of CO2 will cause more heat in water temperatures. This would make the shells of the oysters and clams 'wear away'.
Answer:
yeah the person under me is right
Explanation:
Ocean acidification is a consequence of the excess carbon dioxide in the atmosphere from fossil fuels. When the ocean absorbs the CO2, the water becomes more acidic. Shelled animals like zooplankton, corals, clams, mussels and oysters cannot grow their shells in the acidic water.

offspring, resulting in more individuals each generation having the desired trait
Organisms acquire traits they need and then pass down these acquired
characteristics that they had obtained in their lifetime to their offspring.

Answer:

Explanation:
The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It's also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.

How does the body regulate dopamine
Answer:
Self discipline
Explanation:
Answer:
Inside the brain, dopamine plays important roles in executive functions, motor control, motivation, arousal, reinforcement, and reward, as well as lower-level functions including lactation, sexual gratification, and nausea. The dopaminergic cell groups and pathways make up the dopamine system which is neuromodulatory.
Explanation:
Striatal dopamine release is mediated by vesicular exocytosis. Active zone-like sites are required for rapid and efficient dopamine secretion. Localized dopamine release generates signaling hotspots and is powerfully regulated. Some striatal dopamine release is independent of ascending action potentials.

A species of bird ate many types of seeds, each type coming from a different species
of tree. The birds' beaks varied in size, with some individuals having slightly smaller
beaks and others having slightly larger beaks.
slightly smaller beak
slightly larger beak
A few years went by without much rain, and the only species of tree that survived had
large seeds. Many generations later, almost all the birds had the slightly larger beaks.
How is this best explained?
Answer:
I took this in middle school option 3
Explanation:
Answer:
The bird most likely had to adapt so they had to eat whatever they could. Doing so made their beaks larger, the muscle under neath probably started to grow from all the movement trying to eat the large seeds. LOL i really dont know but it seem reasonable i guess.

What are Green algae?Green algae may be defined as a type of eukaryotic organism that has photosynthetic pigments a and b. Such a type of algae also stores carbohydrates as starch.
Green algae mostly live in freshwater environments, ranging from unicellular flagellates to more complex multicellular forms.
Both land plants and green algae have a photosynthetic organelle known as chloroplast. The cell wall of land plants as well as green algae are made up of cellulose, hemicellulose, and pectins.
Both eukaryotic classifications possess a well-defined cell nucleus, nuclear membrane, and other membrane-bound cell organelles.
Therefore, the correct options for this question are A, B, and E.

How does your model show what happened to the circled rock material as a result of plate motion?
Answer:
Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.
