Answer the following question given this paragraph: The cerebrum is the largest part of the brain. It controls conscious functions such as reasoning, language, sight, touch, and hearing. It is divided into two hemispheres, or halves. The hemispheres are very similar but not identical to one another. They are connected by a thick bundle of axons deep within the brain. Each hemisphere is further divided into the four lobes shown in Figure below . Q: What is the largest part of the brain? A:

OPTIONS:
- cerebellum
- limbic system
- stem
- cerebrum

Answer: cerebrum

Problem: OPTIONS:
- bones
- anterior
- membrane
- cartilage
Q: Answer the following question given this paragraph: Early in the development of a human fetus, the skeleton is made entirely of cartilage. The relatively soft cartilage gradually changes to hard bone through ossification. This is a process in which mineral deposits replace cartilage in bone. At birth, several areas of cartilage remain, including the ends of the long bones in the arms and legs. This allows these bones to keep growing in length during childhood. Q: Early in the development of a human fetus, the skeleton is made entirely of what? A:
Answer: cartilage

Problem:OPTIONS:
- web
- totality
- habitat
- ecosystem

Answer the following question given this paragraph: An ecosystem consists of all the populations in a given area, together with the nonliving environment. Q: What is the name for something that consists of all the population in a given area together with the nonliving environment? A:
****
A: ecosystem

Answer the following question given this paragraph: Binary Fission Due to the relative simplicity of the prokaryotes, the cell division process, called binary fission, is a less complicated and much more rapid process than cell division in eukaryotes. The single, circular DNA chromosome of bacteria is not enclosed in a nucleus, but instead occupies a specific location, the nucleoid, within the cell (Figure 10.2). Although the DNA of the nucleoid is associated with proteins that aid in packaging the molecule into a compact size, there are no histone proteins and thus no nucleosomes in prokaryotes. The packing proteins of bacteria are, however, related to the cohesin and condensin proteins involved in the chromosome compaction of eukaryotes. The bacterial chromosome is attached to the plasma membrane at about the midpoint of the cell. The starting point of replication, the origin, is close to the binding site of the chromosome to the plasma membrane (Figure 10.15). Replication of the DNA is bidirectional, moving away from the origin on both strands of the loop simultaneously. As the new double strands are formed, each origin point moves away from the cell wall attachment toward the opposite ends of the cell. As the cell elongates, the growing membrane aids in the transport of the chromosomes. After the chromosomes have cleared the midpoint of the elongated cell, cytoplasmic separation begins. The formation of a ring composed of repeating units of a protein called FtsZ directs the partition between the nucleoids. Formation of the FtsZ ring triggers the accumulation of other proteins that work together to recruit new membrane and cell wall materials to the site. A septum is formed between the nucleoids, extending gradually from the periphery toward the center of the cell. When the new cell walls are in place, the daughter cells separate. Q: The single circular dna chromosome of bacteria is not enclosed in what, but instead occupies a specific location called the nucleoid within the cell? A:
OPTIONS:
- atom
- molecules
- protons
- nucleus
nucleus

Answer the following question given this paragraph: The metallic bonding model explains the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end. When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals. Q: Why does metal conduct heat and electricity so well? A:
OPTIONS:
- electromagnetism
- free flowing photons
- insulation
- free flowing electrons

Answer: free flowing electrons

input with options: Answer the following question given this paragraph: Metallic bonds are forces of attraction between positive metal ions and the valence electrons that are constantly moving around them (see the Figure below ). The valence electrons include their own and those of other, nearby ions of the same metal. The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. For an animated version of metallic bonding, go to this URL:. Q: What kind of bonds are forces of attraction between positive metal ions and the valence electrons that are constantly moving around them? A:
OPTIONS:
- neutron bonds
- liquid bonds
- ionized bonds
- metallic bonds
output:
metallic bonds
