Q: Answer the following question given this paragraph: Prokaryotic organisms reproduce asexually by binary fission , a process that produces identical offspring ( Figure below ). In asexual reproduction , a single parent produces genetically identical offspring. As prokaryotes do not have a nucleus, and have only one circular chromosome, they do not need to reproduce by the same mechanism as eukaryotic cells; mitosis does not exist in prokaryotic cells . Prokaryotic cell division is a much simpler process. In prokaryotic cell division, after the single chromosome is copied, the cell grows larger. Eventually the two chromosomes separate and move to opposite ends of the cell. Newly formed cell membrane then grows into the center of the cell, separating the two chromosomes, and forming two genetically identical daughter cells. Some eukaryotic organelles, such as mitochondria and chloroplasts, also divide by binary fission. Q: How do prokaryotic organisms reproduce asexually? Choices: - mitosis - residual fission - kinetic fission - binary fission A:
A: binary fission

Q: Answer the following question given this paragraph: Covalent bonds are responsible for many of the properties of covalent compounds. Covalent compounds have relatively low boiling points, cannot conduct electricity, and may not dissolve in water. Q: What is responsible for many properties of covalent compounds, which have relatively low boiling points, cannot conduct electricity, and may not dissolve in water? Choices: - ionic charge - accretion bonds - atomic weight - covalent bonds A:
A: covalent bonds

Q: Answer the following question given this paragraph: In a hydrogen replacement reaction, the hydrogen in the acid is replaced by an active metal. Q: In a hydrogen replacement reaction, the hydrogen in the acid is replaced by what? Choices: - gas - water - oxygen - an active metal A:
A: an active metal

Q: Answer the following question given this paragraph: When charged particles are close enough to exert force on each other, their electric fields interact. Particles with opposite charges attract each other. Particles with like charges repel each other. Q: What happens between particles with opposite charges? Choices: - they become static - they oppose - they repel - they attract A:
A: they attract
