Excessive sugar intake is related to development of dental caries because
A. oral bacteria produce acids that dissolve tooth enamel when they metabolize sugars.
B. sugar leaches calcium and phosphorus out of teeth.
C. salivary amylase dissolves tooth enamel during carbohydrate digestion.
D. sugars make the saliva more alkaline, causing damage to tooth enamel.

Answers

Answer 1

Answer:

The correct answer is A.

Explanation:

Dental caries is a chronic dynamic disease or process that occurs in the tooth structure in contact with microbial deposits. Among the factors that favor the development of dental caries is the excessive consumption of simple sugars. The sugars consumed with the diet constitute the substrate of the oral microflora and initiate the process of cariogenesis. Streptococcus can ferment sugars in the diet to produce primarily lactic acid as the end product of metabolism. This lowers the pH and demineralizes tooth enamel. Cariogenic microorganisms are characterized because they are capable of transporting carbohydrates in competition with other microorganisms, which could be present in the plaque; the rapid fermentation capacity of this substrate made up of sugars and starch and its acidic capacity - acid products - and acidic acid - capable of performing various functions under conditions of extreme acidity. The marked decrease in pH will contribute to the demineralization of the tooth, favoring the appearance of carious lesions in hard tissues: enamel, dentin and cementum.

The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).

Question 2 of 10
Which of the following should be included in a good conclusion?

Answers

Answer:

How to write a conclusion

An effective conclusion is created by following these steps:

Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.

Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.

Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.

Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.

A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood

Answers

the child has the blood type of Ab its obvious

Explanation:

only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele

Thus man's genotype: BO or

[tex] { | }^{b} i[/tex]

Woman's genotype : AO or

[tex] { | }^{a} i[/tex]

When

the children can not have O blood

The children cannot have B blood

means the man have BO

[tex] { | }^{b} i[/tex]

and woman have AA

[tex] { | }^{a} { | }^{a} [/tex]

Because

if man have BB, and woman have AA

children can only have AB

if man have BB, and woman have AO

children can only have AB and B

Answers

Answer:

Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.

A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.

1) Give two pieces of evidence which show that this is an asexual method of reproduction.

2) Explain why all the new tubers will be genetically identical.

Answers

Answer/Explanation:

Asexual reproduction is a type of reproduction in which new organisms that are identical are formed form a parent without the fusion of male and female gametes and do not require fertilization. Offspring formed are usually identical genetically, and are referred to as clones of the parent. Usually, only one parent is involved.

1. Two pieces of evidence that shows the potato growing is an asexual method of reproduction are:

i. Only one parent is involved

ii. The new tubers are identical (clones of the parent)

2. Reasons Why the new tubers will be genetically identical:

i. They grow from 1 parent by asexual reproduction

ii. No mixing of male and female gametes, so no exchange of genes takes place

Answers

Answer:

Explanation:

The correct answer would be pressure gradient.

A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.

In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

The sacrum is a bone formed by the sacral vertebrae, which have fused to give this bone. Above it articulates with the lumbar vertebra, below with the coccyx, which is the last section of the vertebrae column. Lastly, it articulates with the ilium at the sides. The ilium is one of the three bones that makes the hip bone. It is the largest one and in the upper part of the hip bone.

The ischium and pubis, which are the other two bones that form the hip bone, do not articulate with the sacrum, but they articulate with the ilium and with each other.

Often times, it has more to do with makinga profit rather than a legitimate need for something new. Across the United States, beautiful, historic architecture is frequently destroyed tomake way for malls, high-rise apartment buildings, grandiose homes, and other structures. Unfortunately, little is done to protectour history.Over the past several years, it has become increasingly common for big-pame developers to tear down Victorian, Craftsman, and Colonialbuildings. This destruction is often performed with the thought that it is the property that holds the true value, not the structure that sits on it.Likewise, homeowners have begun to value their property's location over the house they have spent many years living in. Little regard is given tothe painstaking details and craftsmanship that went into these buildings, nor the innate beauty of hand-carved woodwork and ornamentation."Out with the old, in with the new" has resulted in people no longer appreciating the history and artistic integrity of our country's oldestbuildings and failing to realize that once "the new" is brought in, "the old" is lost to us forever.It is bad enough that developers and private citizens are blind to the beauty around them; what is worse is that local governments refuse tostep in and prevent this destruction. Cities and towns need to stand up to large developers that flash money around in the name of progress.Rather than allowing developers to tear down old buildings simply to put up new ones, local governments could enact ordinances to preservetheir area's architecture.
