Answer:
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.
Explanation:
Amino acids are the building blocks of protein. There are 20 amino acids that is present in our body where nine of them are an important component in your diet because they are not produced by the cells in the body. These are <span>leucine,</span> histidine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.
Here are the 8 steps of meiosis:
<span>1. Each chromosome makes an identical copy of itself, forming two exact halves called chromatids. The chromosomes then thicken and shorten into a form that is visible under a microscope. The nuclear membrane disappears. </span>
<span>2. Each chromosome is now made up of two chromatids, the original and an exact copy. Similar chromosomes pair with one another, forming homologous chromosome pairs. The paired homologous chromosomes line up at the equator of the cell. </span>
<span>3. The chromosomes separate from their homologous partners and move to opposite ends of the cell. </span>
<span>4. The nuclear membrane reforms and the cell divides. The paired chromatids are still joined. </span>
<span>5. Each cell contains one member of each homologous chromosome pair. The chromosomes are not copied again between the two cell divisions. </span>
<span>6. The chromosomes line up at the equator of the cell. </span>
<span>7. The chromatids pull apart and move to opposite ends of the cell. The nuclear membrane forms around the separated chromosomes, and the cell divide. </span>
<span>8. THE RESULT: Four new cells have formed from the original single cell. Each new cell has half the number of chromosomes present in the original cell.</span>
Answer:the correct option is B
(Streptococcus).
Explanation:
Acute necrotizing ulcerative gingivitis (ANUG) occurs due to poor oral hygiene which encourages plaque to form on teeth, causing inflammation of the surrounding gum tissues. The microorganisms that are known to inhabit the damaged tissues are oral spirochaete which includes Borrelia,Fusobacteria, Bacteroidese and Peptostreptococcus. Streptococcus is not an oral spirochaete therefore is excluded. I hope this helps.
