Explain how cells obtain energy?
Answers
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
Answer:
Cells perform the functions of life through various chemical reactions. A cell’s metabolism refers to the combination of chemical reactions that take place within it. Catabolic reactions break down complex chemicals into simpler ones and are associated with energy release. Anabolic processes build complex molecules out of simpler ones and require energy. In studying energy, the term system refers to the matter and environment involved in energy transfers.

(17 points) In which of the following circumstances would it be most likely for large organic molecules to form during a laboratory experiment?
Answers
Answer: The correct answer is : B. Laboratory experiments do not generally reflect real-life circumstances.
Explanation: One of the advantages of laboratory experiments is that cause-effect relationships are easier to consider. In a laboratory the independent variables are manipulated by the experimenters.
It is most likely that large organic molecules form during a laboratory experiment if RNA segments that could act as catalysts formed.
RNA is single-strand nucleic acid composed of a long chain of nucleotides, which can act as genetic material in viruses.Moreover, there are specific RNA molecules that also have catalytic (enzymatic) functions called ribozymes.In consequence, RNA ribozymes have dual functions since these molecules can act both as catalysts (i.e., enzymatic proteins) and genetic material (like DNA in organisms or RNA in viruses).In conclusion, it is most likely that large organic molecules form during a laboratory experiment if RNA segments that could act as catalysts formed.

A cup of water is surrounded by air at room temperature. How could you collect evidence to determine whether this system is at equilibrium?
Answers
Answer:
By measuring temperature and looking at the motion of the water in the cup, one can collect evidence to determine whether this system is at equilibrium
Explanation:
For any system to be in equilibrium there must be no transfer of heat and energy or motion between the system and the surrounding environment. If there is no change in the temperature and energy or motion of the cup of water, then it can be said that the system is in equilibrium.

The ribbon eel (Rhinomuraena quaesita), also known as the leaf-nosed moray eel or bernis eel, is a species of moray eel, the only member of the genus Rhinomuraena. What is now known as R. quaesita also includes the former R. amboinensis. R. quaesita was used for blue ribbon eels and R. amboinensis for black ribbon eels, but these are now recognized as the same species. The ribbon eel is found in lagoons and reefs in the Indo-Pacific ocean, ranging from East Africa to southern Japan, Australia and French Polynesia.[1][2] This species is widely distributed and is frequently seen by divers in Indonesian waters with their heads and anterior bodies protruding from crevices in sand and rubble habitats from very shallow to about 60 m.[3] Although generally placed in the moray eel family Muraenidae, it has several distinctive features leading some to place it in its own family, Rhinomuraenidae....[1]
