Answer:

1. N/A

2. a cell

3. organ system

4.Tissues are groups of similar cells that have a common function. While an organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.

nervous system - The nervous helps the whole body communicate, our body needs to communicate so we can actually do things like breathing.

respiratory system - The respiratory system gives cells the oxygen they need to survive, and cells keep humans alive. Humans cannot survive without breathing.

digestive system - The digestive system is important for breaking down foods into nutrients, those nutrients are then used to heal and nourish the human body. The digestive system also helps us pass toxic wastes that build up in our bodies, so we don't get sick.

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

Answers

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.

you answer this questions

Answers

The Mendel's laws of inheritance include law of dominance, law of segregation and law of independent assortment.

Some of the key elements of Mendel’s original model were:
Heritable traits are determined by heritable factors, now called genes. Genes come in pairs (that is, are present in two copies in an organism).
Genes come in different versions, now called alleles. When an organism has two different alleles of a gene, one (the dominant allele) will hide the presence of the other (the recessive allele) and determine appearance.
During gamete production, each egg or sperm cell receives just one of the two gene copies present in the organism, and the copy allocated to each gamete is random (law of segregation).
Genes for different traits are inherited independently of one another (law of independent assortment).

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.

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.

How does the body regulate dopamine

Answers

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.
