According to the U.S. Department of Energy, a typical home in the United States uses approximately 900 kWh of electricity per mo

guapka [62]

Based on the energy generated by the power plant annually, the number of households the plant can support:

if energy usage is 10,800 kWh/year = 365000 households
if energy usage is 24000 kWh/year = 164250 households

<h3>What is electrical energy?</h3>

Energy is energy that is due to movement of electrically charged particles.

Electrical energy is used in homes for many purposes.

Electrical energy is sold in units of kWh.

Data provided:

Capacity of power plant = 500 MW

Capacity factor = 0.9

Average annual household energy usage = 10,800 kWh/year

Energy generated in a year = 24 × 365 × 0.9 × 500 MW = 3,942,000 MWh/year

3,942,000 kWh/year = 3,942,000,000 kWh/year.

Number of households the power plant can support = 3,942,000,000 kWh/10800 = 365000 households

Number of households the power plant can support is 365000 households

If monthly electricity usage increases to 1,200 kWh

In a year, energy usage = 1200 × 12 = 24,000 kWh/ year

Number of households the plant can support = 3,942,000,000 kWh/24,000 = 164250 households

Therefore, based on the energy generated by the power plant annually, the number of households the plant can support:

if energy usage is 10,800 kWh/year = 365000 households
if energy usage is 24000 kWh/year = 164250 households

In at least five (5) sentences summarize how humans are changing the carbon cycle?

Serga [27]

Answer:

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

puteri [66]

Short-term memory holds information for 15 to 25 seconds and stores it according to its meaning rather than just as mere stimulation. However, it is not really true that short-term memory can be retained only for this short amount of time. It has been shown in different studies that it can be held even longer.

Flow Chart What happens to food and energy when it enters the cell? Finish the description for each organelle. Step 1: Mitochond

torisob [31]

Explanation:

Eukaryotic cells have specialized mechanisms to transport molecules along with membrane-bound organelles like the endoplasmic reticulum that provide a higher surface area for absorption and enable more efficient transportation.

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. Several organelles facilitate the digestion of nutrients into metabolites and energy...

Step 1: Mitochondria break down food and release energy; In all eukaryotic cells mitochondria are small cellular organelles bound by membranes. The higher concentrations of reactants and solutes, increases metabolic reaction efficiency; these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is obtained via the breakdown of nutrients from food, and is stored within the molecule ATP. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm) where several metabolites used for building other compounds are produced.

Step 2: Lysosomes... Some organelles separate proteins and molecules that may harm the cell by parceling them into membrane-bound organelles for example, proteases bound within lysosomes can break down many structural proteins, and carbohydrates found in food, waste, and cell components

Step 3: Vacuoles... Vacuoles are fluid filled organelles which store concentrated amounts of solutes, and waste products. Specialized vacuoles are also used to transport components to the cell membrane for cellular export.

Step 4: The endoplasmic reticulum... Most proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes in the rough endoplasmic reticulum. The rest of the ER, which does not contain ribosomes is called the smooth ER, and may contain lipids, enzymes, and other proteins. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.
Step 5: Golgi bodies... Like a post office, the golgi complex, or golgi body recognizes signal sequences and packages these compounds into lysosomes for delivery to their final destination. Lysosomes fuse with the plasma membrane to empty their contents into the extracellular space.

I need help with this question. Please help me!<br><br> Why do organisms need enzymes?

Alla [95]

Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

Hope this helped
