Answer: C. warfarin.

Explanation:

Warfarin has been the cornerstone of oral anticoagulant therapy for about 50 years. Its effectiveness has already been proven in the prevention of venous thromboembolism in the prevention of systemic embolism in patients  with cardiac valve prostheses or atrial fibrillation and the prevention of acute myocardial infarction (MI) in high-risk men. Warfarin mainly inhibits the vitamin K epoxide reductase enzyme, which prevents the cyclic interconversion of this vitamin. This way, by blocking the cyclic interconversion of vitamin K prevents carboxylation of glutamate residues in terminal regions in K-dependent proteins.  Warfarin is the most commonly used oral anticoagulant in clinical practice and is composed of two isomers, R-warfarin, and S-warfarin (5 times more potent than R-isomer), which are metabolized in the liver by different routes.

identify the steps in the scientific method that correspond to hunt's experiments is

Observation: Mice in plastic cages that had been treated with strong soap had eggs that had cell division issues that resulted in genetic abnormalities.

Hypothesis: Exposure to bisphenol A affects the prevalence of genetic defects in mice.

Prediction: Mice exposed to high amounts of bisphenol A will have an increase in the incidence of genetic anomalies.

What is Morgan hunt's experiment?

Morgan's arguments against the Mendelian and chromosomal theories were very different. Both hypothesized cellular structures or substances that somehow regulate developmental processes in an effort to explain biological occurrences. This reminded Morgan too much of the preformation theory, which held that the adult is already fully formed in the egg or sperm and dominated embryology in the late 18th and early 19th centuries.

Morgan contended in 1909 and 1910 that no single chromosome could contain particular hereditary qualities, despite the fact that he acknowledged that the chromosomes might have something to do with heredity. Additionally, he asserted that Mendelian theory was completely hypothetical because it was unable to define the actual processes of heredity, despite being able to explain and even forecast breeding outcomes.

For Morgan, the fact that each pair of chromosomes divides and that each chromosome thereafter enters a different sperm or egg cell in precisely the same way as Mendelian factors did not seem to be sufficient evidence to support the idea that the two processes are related.

True. Greenhouse gases are composed of many molecular components that provide and are necessary for life to still exist on earth. For example, the carbon dioxide and the others alike. However, when these exceed the necessary level and amount in the atmosphere, they cause tremendous increase in temperature.
