Answer the following question given this paragraph: Particles with opposite electric charges attract each other. This explains why negative electrons orbit the positive nucleus. Particles with the same electric charge repel each other. This means that the positive protons in the nucleus push apart from one another. So why doesn't the nucleus fly apart? An even stronger forcecalled the strong nuclear forceholds protons and neutrons together in the nucleus. You can learn more about these forces in the nucleus by watching the video at this URL:. Q: Particles with what type of electric charges attract each other? Choices: - similar - same - simple - opposite A:
opposite
Answer the following question given this paragraph: We all start as a single cell and soon grow into an embryo. Notice the remarkable details beginning to form. The eyes, backbone, and limb buds are obvious. Think about the amazing complexity that must be going on inside the embryo, and the tremendous amount of growth and development still to come. So, yes, at one time we all looked similar. Q: We all start as a single cell and soon grow into what? Choices: - nucleus - uterus - egg - embryo A:
embryo
Q: Answer the following question given this paragraph: Atomic emission spectra are produced when excited electrons return to ground state. Q: Atomic emission spectra are produced when excited electrons return to what state? Choices: - orbital state - work state - side state - ground state A:
A: ground state
Question: Answer the following question given this paragraph: This giant Buddha statue, which is a national treasure in Japan, is made of bronze. Bronze consists mainly of copper but also contains some tin. Bronze is an example of a solution. A solution is a type of mixture that has the same composition throughout. Q: What do you call a type of mixture that has the same composition throughout? Choices: - transition - structure - transfusion - solution A:
Answer: solution

Answer the following question given this paragraph: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two phospholipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Q: What is a double membrane of the nucleus that encloses the genetic material? Choices: - the complex envelope - the cell wall - the nuclear compression - the nuclear envelope A:
**Answer**
the nuclear envelope
