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:
binary fission
Answer the following question given this paragraph: Arteries carry blood away from the heart, while veins return blood to the heart. Q: What carries blood away from the heart? Choices: - veins - pores - capillaries - arteries A:
arteries
Q: Answer the following question given this paragraph: The body does not exist in isolation. There is a constant input of water and electrolytes into the system. While osmoregulation is achieved across membranes within the body, excess electrolytes and wastes are transported to the kidneys and excreted, helping to maintain osmotic balance. Q: The body does not exist in isolation. there is a constant input of water and electrolytes into the system. while osmoregulation is achieved across membranes within the body, excess electrolytes and wastes are transported to the kidneys and excreted, helping to maintain this? Choices: - physical balance - vacuum balance - nucleic balance - osmotic balance A:
A: osmotic balance
Question: Answer the following question given this paragraph: 16.4 The Simple Pendulum A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15. The period of a simple pendulum is. Q: A mass suspended by a wire is a simple type of what and undergoes simple harmonic motion for amplitudes less than about 15 degrees? Choices: - gravity - variation - weight - pendulum A:
Answer: pendulum

Answer the following question given this paragraph: Bathymetric maps are made from depth soundings or sonar data. They help oceanographers understand the shape of bottoms of lakes, bays, and the ocean. This information also helps boaters navigate safely. Q: Besides depth soundings, what else are bathymetric maps made of? Choices: - intensity data - solar data - density measures - sonar data A:
**Answer**
sonar data

Answer the following question given this paragraph: Proteins Function as Enzymes If you were trying to type a paper, and every time you hit a key on your laptop there was a delay of six or seven minutes before you got a response, you would probably get a new laptop. In a similar way, without enzymes to catalyze chemical reactions, the human body would be nonfunctional. It functions only because enzymes function. Enzymatic reactionschemical reactions catalyzed by enzymesbegin when substrates bind to the enzyme. A substrate is a reactant in an enzymatic reaction. This occurs on regions of the enzyme known as active sites (Figure 2.27). Any given enzyme catalyzes just one type of chemical reaction. This characteristic, called specificity, is due to the fact that a substrate with a particular shape and electrical charge can bind only to an active site corresponding to that substrate. Q: What is the name of a reactant in an enzymatic reaction? Choices: - membrane - Scar - tissues - substrate A:
(A).
substrate
