Answer:
Placebo effect
Explanation:
People tend to think they've been cured by something even if the something isn't effective, and they might even experience minor symptoms of having been effectively treated. If people know that the drug they're being given is the one being tested, they'll be more likely to experience this effect because it's the drug that the researchers think is going to work. Researchers conduct double-blind studies to prevent bias in the researchers and to prevent the placebo effect from interfering with the results from the test subjects.
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.
Chloroplasts' main role is to conduct photosynthesis<span>, where the photosynthetic pigment </span>chlorophyll<span> captures the </span>energy<span> from </span>sunlight<span> and converts it and stores it in the energy-storage molecules </span>ATP<span> and </span>NADPH<span> while freeing </span>oxygen<span> from water. They then use the ATP and NADPH to make organic molecules from </span>carbon dioxide<span> in a process known as the </span>Calvin cycle<span>. </span>
The right answer is He is studying oxygen, which can also be found in proteins.
Carbon atoms could also be a right answer if there was a statement...
Sugars, composed only of carbon atoms, hydrogen, and oxygen, are the simplest energetic nutrients. Example to (C6H12O6): If we look at the chemical formula for glucose, we can see that the proportion Hydrogen / Oxygen corresponds to that of water (H2O)
Lipids also consist of carbon atoms (C), hydrogen (H) and oxygen (O), but fatty acids are molecules that are low in oxygen. Example: Linoleic acid C18H32O2
