Q: Answer the following question given this paragraph: Bacteria called cyanobacteria are very important. They are bluish green in color (see Figure below ) because they contain chlorophyll. They make food through photosynthesis and release oxygen into the air. These bacteria were probably responsible for adding oxygen to the air on early Earth. This changed the planet's atmosphere. It also changed the direction of evolution. Ancient cyanobacteria also may have evolved into the chloroplasts of plant cells. Q: Cyanobacteria are bluish green in color because they contain what? A:

OPTIONS:
- chloroplasts
- microbial
- carbonate
- chlorophyll

A: chlorophyll

input: OPTIONS:
- Biggest bang
- Explosive bang
- major bang
- big bang Now, answer this question: Answer the following question given this paragraph: H0 = 20km/s Mly. Explanations of the large-scale characteristics of the universe are intimately tied to particle physics. The dominance of matter over antimatter and the smoothness of the CMBR are two characteristics that are tied to particle physics. The epochs of the universe are known back to very shortly after the Big Bang, based on known laws of physics. The earliest epochs are tied to the unification of forces, with the electroweak epoch being partially understood, the GUT epoch being speculative, and the TOE epoch being highly speculative since it involves an unknown single superforce. The transition from GUT to electroweak is called spontaneous symmetry breaking. It released energy that caused the inflationary scenario, which in turn explains the smoothness of the CMBR. Q: The epochs of the universe are known back to very shortly after what 'explosive' event? A:
A:
output: big bang

Q: Answer the following question given this paragraph: Figure 12.11 shows schematically how laminar and turbulent flow differ. Layers flow without mixing when flow is laminar. When there is turbulence, the layers mix, and there are significant velocities in directions other than the overall direction of flow. The lines that are shown in many illustrations are the paths followed by small volumes of fluids. These are called streamlines. Streamlines are smooth and continuous when flow is laminar, but break up and mix when flow is turbulent. Turbulence has two main causes. First, any obstruction or sharp corner, such as in a faucet, creates turbulence by imparting velocities perpendicular to the flow. Second, high speeds cause turbulence. The drag both between adjacent layers of fluid and between the fluid and its surroundings forms swirls and eddies, if the speed is great enough. We shall concentrate on laminar flow for the remainder of this section, leaving certain aspects of turbulence for later sections. Q: Streamlines are smooth and continuous when flow is laminar, but break up and mix when flow is what? A:
Answer: turbulent

Answer the following question given this paragraph: Chromosomal Disorders Sometimes a genetic disease is not caused by a mutation in a gene, but by the presence of an incorrect number of chromosomes. For example, Down syndrome is caused by having three copies of chromosome 21. This is known as trisomy 21. The most common cause of trisomy 21 is chromosomal nondisjunction during meiosis. The frequency of nondisjunction events appears to increase with age, so the frequency of bearing a child with Down syndrome increases in women over 36. The age of the father matters less because nondisjunction is much less likely to occur in a sperm than in an egg. Whereas Down syndrome is caused by having three copies of a chromosome, Turner syndrome is caused by having just one copy of the X chromosome. This is known as monosomy. The affected child is always female. Women with Turner syndrome are sterile because their sexual organs do not mature. Q: Down syndrome is caused by having three copies of what, a condition known as trisomy? A:
****
A:
chromosome
