Arecent encyclopedia entry about dogs cites multiple research papers done by scientists at veterinary schools. according to the article, labrador retrievers come in two specific breeds: english and american. the english breed is described as stocky and heavy, while the american breed is described as tall and lanky. the article describes current scientific research as showing that males of both breeds usually weigh about 29-41 kg (65-90 lb), and females weigh 25-32 kg (55-70 lb). coat colors for both breeds come in solid black, yellow, or chocolate. all labs have strong tails and webbed feet, which them swim. devon would like to use this information to determine if his new dog is an english or american labrador retriever. which best describes the reliability of the information? a it is not reliable because only scientists can use scientific information for reference. b it is not reliable because it doesn’t talk about how to test and only gives data about the breeds. c it is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools. d it is reliable because it gives information about both types of labradors in addition to information about other types of dogs.

The correct answer will be option-C.

Explanation:

Scientific research can be performed using the scientific method which includes several steps. The steps involved begins with making an observation, asking a question, doing background research, proposing a hypothesis, performing experiments and analyzing the results to suggest the conclusion.  

Since in the given question, the scientist used and cited the research papers of various scientists by doing background research and provided the evidence from the related research papers to support the evidence.

Therefore, the research paper could be considered valid, reliable as well as scientific

Thus, Option-C is the correct answer.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
