The answer is the second one: a large protein.

Explanation for each option:

  1. Atom: Atoms are much smaller than viruses. An atom typically measures about 0.1 nanometers in diameter, whereas viruses are generally in the range of 20 to 300 nanometers. Therefore, a virus is not similar in size to an atom.

  2. Large protein: This is the correct answer. Large proteins and viruses can be similar in size. Proteins can vary greatly in size, but some large proteins can be comparable to small viruses, which makes this option the most accurate.

  3. Electron: Electrons are subatomic particles and are much smaller than viruses. Electrons do not have a defined size in the same way as atoms or molecules, but they are significantly smaller than viruses.

  4. Bacterium: Bacteria are generally larger than viruses. While viruses range from 20 to 300 nanometers, bacteria are typically about 1,000 nanometers (1 micrometer) or larger. Therefore, a virus is not similar in size to a bacterium.

In summary, a virus is similar in size to a large protein.

Infinity stones release energy in forms of heat, radiation, and blast work. Assume that an immortal being has collected 2 infinity stones, each capable of producing 5000 tera-Joules (TJ) of energy. If both stones are used simultaneously, how much heat, in SI units of TJ, is supplied from the stones if 30% of the energy produced by the stones is in the form of heat? On Canvas, submit only the magnitude value associated with the proper units; do not include units in your answer online. For instance, for an answer of 10.5 lbf, enter 10.5 into the answer position in Canvas. Do not use scientific notation.
