in reefs
Answer the following question given this paragraph: A virus is a sub-microscopic particle that can infect living cells. Viruses are much smaller than prokaryotic organisms. In essence, a virus is simply a nucleic acid surrounded by a protein coat, as seen in the Figure below . This outer coat is called a capsid . Viruses will be discussed in more detail in the Viruses concepts. Q: In essence, a virus is simply a nucleic acid surrounded by what? Choices: - a membrane coat - a polymer coat - a polypeptide - a protein coat A:
a protein coat
Q: Answer the following question given this paragraph: 7.4 Conservative Forces and Potential Energy 9. What is a conservative force? 10. The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer dives from it, starting just before the swimmer steps on the board until just after his feet leave it. Define mechanical energy. What is the relationship of mechanical energy to nonconservative forces? What happens to mechanical energy if only conservative forces act? 12. What is the relationship of potential energy to conservative force?. Q: The force exerted by a diving board is conservative, provided the internal friction is this? Choices: - static - intrinsic - significant - negligible A:
A: negligible
Question: Answer the following question given this paragraph: You consist of a great many cells, but like all other organisms, you started life as a single cell. How did you develop from a single cell into an organism with trillions of cells? The answer is cell division. After cells grow to their maximum size, they divide into two new cells. These new cells are small at first, but they grow quickly and eventually divide and produce more new cells. This process keeps repeating in a continuous cycle. Q: What process allows an individual to develop from a single cell into an organism with trillions of cells? Choices: - cell transition - Cell multiplication - cell function - cell division A:
Answer: cell division
