Answer: The correct answer is respiratory route.
Explanation: Disease can be transmitted from human to human through respiratory route. This can occur when the infected person cough or sneeze into the air , some particles of the pathogens are released and there is any human around the infected person when he sneez or cough, the person tend to get infected by inhaling or breathing in the infected air.
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.
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.

Explanation:
An anaerobic metabolic pathway that results in the production of two net ATPs per glucose plus two pyruvic acid molecules is glycolysis True False
Answer: True.
Explanation:
Glycolysis is a process that occurs in the cell cytoplasm, in which a 6-carbon glucose molecule is cleaved into two 3-carbon pyruvate molecules. Two molecules of ATP (Adenosine triphosphate, a molecule that acts as a source of energy to perform biological processes.) and two molecules of NADH are also obtained. It is a metabolic pathway responsible for oxidizing glucose in order to obtain energy for the cell. It consists of a series of consecutive enzymatic reactions, and when pyruvate is obtained, it continues to be used in other metabolic pathways in order to continue delivering energy to the organism. Glycolysis takes place both in the absence and presence of oxygen, so it is defined as an anaerobic process. Therefore, the final destination of the products obtained in glycolysis will depend on the conditions of the environment in which it is found, which will determine the metabolic pathway to be followed (i.e., whether oxygen is available or not). In the absence of oxygen, glucose will not be completely oxidized to carbon dioxide and water, generating fermentative products (lactic acid in animals and ethanol in yeast) producing only two net ATP molecules. In the presence of oxygen, the pyruvate obtained during glycolysis enters the Krebs cycle (to produce energy in usable form as ATP or GTP) and then undergoes oxidative phosphorylation (the process by which ATP is formed as a result of electron transfer from NADH or FADH2 to oxygen via a series of electron transporters) producing a net gain of between 36-38 ATP.

do thyroid hormones influence heart rate from influencing the heart itself, or the attached to it?
Answer:
An excess of thyroid hormones increases cardiac contractility and resting heart rate (see box below). Cardiac output may increase by 50-300 per cent as a result of the combined effect of increases in resting heart rate, contractility, ejection fraction and blood volume, with a concomitant decrease in SVR.

a penny is tossed and comes up heads 7 out of 10 times. Is the probability that it will be heads on the next toss 70%? Why or not?
Answer:
I think it will because when you express 7/10 as a fraction it will result to 0.7, meaning the probability between 0 and 1 will be 0.7, therefore to express 0.7 as a fraction the answer will be 70%..

In a population of mole-rats, some have a little larger teeth and longer claws. If those particular mole-rats survive because they can dig quicker and the others are preyed on and do not survive to reproduce, what will eventually happen in subsequent generations?
Answer:
One increase in population and the other decrease.
Explanation:
The population of the rats having little larger teeth and longer claws increases as compared to those rats having small teeth and shorter claws because the rats can escape from their predators and survive in that environmental conditions. The population of rats having small teeth and shorter claws extinct in the end due to no reproduction and preyed by the predators and dominated by the population of the rats having little larger teeth and longer claws due to their features.

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 ❤️Compare and contrast the cell structures / organelles found in plant and animal cells.

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.

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.
