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.
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.
What's the importance of sun in power supply??
Answer:
It provides solar energy to supply power through solar panels
Answer:
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.

In a forest ecosystem, spotted owls make their homes in the cavities of dead trees. Thissame habitat is home to the rodents that the owls feed on. Human activities, such as logging,have caused the population of the spotted owl to decline. From this information, what statement BEST explains the relationship between humans and the spotted owl
Options are given in the comment section:
Answer:
The correct answer is - Humans have taken away resources needed by the owls, so there are fewer owls.
Explanation:
In this question, it is established that the trees are the habitat for the owls, and also these trees help in their food resources as these trees are habitat of rodents also.
By logging, humans destroy the habitat of both owls and rodents they feed on and important for their growth and survivability. Humans have caused the removal of required resources for the owls therefore, there are fewer owls.

The role played by the systems of the body in ensuring survival of farm animals in hot and dry climates
Answer:
Answer to the following question is as follows;
Explanation:
Domesticated animals have a natural instinct to seek out cover and seek refuge from the scorching heat. Their bodies, on the other hand, have inherent defensive systems to help them cope with heat and dryness. One of these is their covering or fur, which gives sun protection.
Animals living in hot, dry climates consume a lot of water, which is subsequently stored in their tissues to keep them from becoming dehydrated. Sweating is accomplished by certain animals by keeping their mouths open.

Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell. The presence of these organelles tells you that the environment Group of answer choices is hypotonic to the protozoan. contains a higher concentration of solutes than the protozoan. is isotonic to the protozoan. is hypertonic to the protozoan.
Answer:
is hypertonic to the protozoan.
Explanation:
The presence of contractile vacuoles tells us that the environment is hypertonic to the protozoan that contains a higher concentration of solutes in the outside environment than the protozoan. The water moves outside the cell if its concentration is higher inside the cell so due to diffusion and no need of extra water, the water removes by the contractile vacuole to the outside environment so we can say that the environment is is hypertonic to the protozoan.
Why is it possible for a FPR (formyl-peptide receptor) to detect a formyl peptide in the
absence of a bacterial infection?
Answer:
These receptors were originally identified by their ability to bind N-formyl peptides such as N-formylmethionine produced by the degradation of either bacterial or host cells. Hence formyl peptide receptors are involved in mediating immune cell response to infection.Mark me as brainliest ❤️Limestone, which contains the mineral calcite that fizzes in weak acid, may change

You treat a sample of DNA with DNase and run the digested fragments out on an electrophoretic gel. You found mostly long fragments. What can you conclude about this sample of DNA
Answer:
the sample contains mostly heterochromatin
Explanation:
Heterochromatin refers to a highly condensed state of DNA, whereas euchromatin is lightly packed. It is for that reason that heterochromatin is associated with a transcriptionally inactive state, whereas euchromatin regions are active for transcription. Heterochromatin regions resist DNases because these enzymes don't cut DNA randomly, but they show sequence preference. In consequence, highly repetitive DNA heterochromatin regions (e.g., centromeres, telomeres, etc) may exhibit resistance to DNA cleavage.

Explain how fluctuations in abiotic cycles can influence populations.
Answer:
Populations are influenced by fluctuations in any of the abiotic cycles. The fluctuation of seasonal cycles can cause populations to hibernate, migrate, or breed. Organisms hibernate as a result of seasonal fluctuations that cause them to have a limited resource supply.

which type of plant was important in establishing the transition from water to land and the dominance of gametophyte
Answer: Nonvascular plants
Explanation:
Non-vascular plants are the plants that do not have a vascular system that has a xylem and phloem but rather, they have simpler tissues which have specialized functions that are used in the internal transport of water.
The type of plant that was important in establishing the transition from water to land and the dominance of gametophyte is the non vascular plant.

What is the main function of the structure that is identified as A in the picture above?
It anchors the plant.

It supports the plant.
Answer:
It supports the plant.Explanation:
Below are the three main organs that make up the plant body.
The parts of a plant are labeled. The top green leaf part is labeled A. The stem is labeled B. The part that is underground is labeled C.
What is the main function of the structure that is identified as B in the picture above?
It anchors the plant.
It produces food.
It absorbs nutrients.
It supports the plant.The main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option, as plant leaves are essential for the survival and growth of plants, enabling them to produce food, exchange gases, and regulate water balance.
What is the plant leaves function?Leaves are the primary site for photosynthesis, the process by which plants use sunlight, water, and carbon dioxide to produce food (glucose) and oxygen. Leaves also play a crucial role in gas exchange, allowing plants to take in carbon dioxide and release oxygen during photosynthesis and release carbon dioxide and take in oxygen during respiration. Leaves are responsible for transpiration, the process by which water is absorbed by the roots and transported through the plant to the leaves, where it is released into the air through tiny openings called stomata.
Hence, the main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option.

Recently discovered genetic evidence shows that multicellular land plants such as corn and wheat, are all of one lineage – they all arose from a single type of algae. Fossil evidence suggests that other types of algae did not have the needed complexity to move into terrestrial ecosystems. Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1) they would need a host or vessel to stay on and feed of of their body
2) they would need some for of reproduction in the host ( mitosis whatever the algae my use )
3) they would need to wisely choose there hosts and of what they feed on so there host doesn’t die quickly
