Place the steps involved in burning coal to create electricity in the correct order.
butalik [34]

Answer and Explanation:

  1. Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area.
  2. Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam.
  3. Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines.
  4. Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.

Alchen [17]

Answer:

6 Kolalas

Explanation:

The maximum number of koalas that can survive in the area is 6.

Each koala must eat 200 grams of leaves per day.

The trees in an area can provide a total of 1380 g of leaves per day.

The maximum number of koalas that can survive in this area would be the total amount of leaves production per day divided by the amount of leaves required by each koala per day.

Number of koala the area can support = 1380/200 = 6.9

olya-2409 [2.1K]

Answer:

The correct answer is - Ploidy is the number of sets of chromosomes in a biological cell.

Explanation:

Ploidy is the number of sets of the chromosome in a living cell. Ploidy is known for different condition such as haploid, diploid, and aneuploid, and many more depends how many homologues chromosome numbers are present in the cell.

Diploid cells are common in many organisms where one chromosome come from the mother gamete and the other from the father gamete and makes the homologues chromosomes. In diploid homologues, chromosome are 2n where n is the number of homologues of each chromosome.

In haploid there is only one set of each chromosome and mainly takes place by meiosis. In aneuploidy is the condition where the number of homologues chromosomes are not as the normal genome of the organism for example in humans instead of 46 chromosomes there 45 or 47 chromosome found.

How long does it normally take to process one 12-ounce beer from your system?
Darina [25.2K]

Once the alcohol goes into our system, an ounce of it is process for a period of one hour.

The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.

Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.
