Q: Gene expression and what else are usually considered the same molecular process? Read this paragraph and choose the correct option from the provided answers: Gene expression and protein synthesis are usually considered the same molecular process.

protein synthesis

Q: What occurs when an unstable nucleus emits an alpha particle and energy? Read this paragraph and choose the correct option from the provided answers: Alpha decay occurs when an unstable nucleus emits an alpha particle and energy. The diagram in Figure below represents alpha decay. An alpha particle contains two protons and two neutrons, giving it a charge of +2. A helium nucleus has two protons and two neutrons, so an alpha particle is represented in nuclear equations by the symbol . The superscript 4 is the mass number (2 protons + 2 neutrons). The subscript 2 is the charge of the particle as well as the number of protons. Choices: - radar decay - nucleus decay - alpha radition - alpha decay A:
alpha decay

Q: What do organisms use to store energy? Read this paragraph and choose the correct option from the provided answers: A lipid is an organic compound such as fat or oil. Organisms use lipids to store energy, but lipids have other important roles as well. Lipids consist of repeating units called fatty acids. Fatty acids are organic compounds that have the general formula CH 3 (CH 2 ) n COOH, where n usually ranges from 2 to 28 and is always an even number. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Choices: - tissues - proteins - metabolytes - lipids A:
lipids
