Bacteria and food can cause tooth decay. A clear, sticky substance called plaque is always forming on your teeth and gums. Plaque contains bacteria that feed on the sugars in the food you eat. ... Eating foods that are high in sugar and other carbohydrates, which feed the bacteria in your mouth.

After having meals, a sticky layer will be formed on the tooth. It's called a plaque. When you eat something, the bacteria in the plaque will undergo anaerobic respiration and will turn the sugar in your food into acid. The other layer of tooth, enamel, may be corroded by the acid formed. When the enamel is corroded, the dentine and pulp cavity will be exposed, and bacteria may get into it and attack them. That's how tooth decay is formed.

Approximately how many gallons of water are used per year in a typical home? 1 million gallons 500,000 gallons 150,000 gallons 1

Advocard [28]

146 gallons of water

<h2>Further explanation </h2>

The human need for water (for drinking) is 8 glasses a day or about 2 liters. 1 gallon usually contains 19-20 liters. One house usually consists of 4 people (father, mother, brother, sister).

If one person consumes 2 liters of water, then one house will consume about 8 liters a day.

Which will take up 2 gallons in 5 days.

1 Year = 365 days

365 days : 5 days (2 gallons) = 73 (gallon water refill frequency)

73 x 2 = 146

So, within 1 year the level of gallon water consumption in an ordinary house consumes 146 gallons of water.

That is the calculation of the use of gallons for consumption, not for bathing, washing, pooping, urinating, etc.

Which amino acids are the primary nitrogen donors for biosynthetic reactions in the cell?

prohojiy [21]

Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell. Glutamine is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. Glutamate is generally acknowledged to be the most important transmitter for normal brain function. Nearly all excitatory neurons in the central nervous system are glutamatergic, and it is estimated that over half of all brain synapses release this agent. Glutamate plays an especially important role in clinical neurology because elevated concentrations of extracellular glutamate, released as a result of neural injury, are toxic to neurons
