Answer the following question given this paragraph: The answer is actually "no. " A virus is essentially DNA or RNA surrounded by a coat of protein ( Figure below ). It is not made of a cell , and cannot maintain a stable internal environment ( homeostasis ). Recall that a cell is the basic unit of living organisms. So if a virus is not made of at least one cell, can it be living? Viruses also cannot reproduce on their ownthey need to infect a host cell to reproduce. So a virus is very different from any of the organisms that fall into the three domains of life. Q: A virus is essentially dna or rna surrounded by a coat of what? Choices: - acids - paint - organism - protein A:
**Answer**
protein

Answer the following question given this paragraph: The universe has many remarkable qualities, among them a rather beautiful symmetry: the total amount of motion in the universe balances out always. This law only makes sense if we measure "motion" in a specific way: as the product of mass and velocity. This product, called momentum , can be exchanged from one object to another in a collision. The rapidity with which momentum is exchanged over time is determined by the forces involved in the collision. Conservation of momentum is one of the five fundamental conservation laws in the universe. The other four are conservation of energy, angular momentum, charge conservation and CPT conservation. Q: One of the five fundamental conservation laws in the universe refers to conservation of what, which is the product of mass and velocity? Choices: - fluid - energy - light - momentum A:
**Answer**
momentum

Answer the following question given this paragraph: We can see two general types of effects when humans are exposed to radiation. Low-level exposure can lead to development of cancer. The regulatory processes regulating cell growth are disrupted, leading to uncontrolled growth of abnormal cells. Acute exposure can produce nausea, weakness, skin burns, and internal tissue damage. Cancer patients receiving radiation therapy experience these symptoms, but the radiation is targeted to a specific site in the body so that the damage is primarily to the cancer cells and the patient is able to recover from the exposure. Q: Low-level exposure of humans to radiation can cause what? Choices: - illness - coughing - bleeding - cancer A:
**Answer**
cancer
