Answer the following question given this paragraph: Many people think that any idea that is completely accepted in science is a law. But that is not true. In science, a law is something that always applies under the same conditions. A law explains a fairly simple phenomenon. A theory is much more complex: it tells you why something happens. A law only tells you that it happens. For example, if you hold something above the ground and let go, it will fall. This phenomenon is recognized by the law of gravity ( Figure below ). Some people say that evolution is "just a theory. " But for a complex explanation like evolution, theory is the right word. Q: In science, what do you call something that always applies under the same conditions? Choices: - theory - hypothesis - scientific method - scientific law A:
scientific law
Q: Answer the following question given this paragraph: Figure 42.13 B cell receptors are embedded in the membranes of B cells and bind a variety of antigens through their variable regions. The signal transduction region transfers the signal into the cell. Q: What are embedded in the membranes of b cells and bind a variety of antigens through their variable regions? Choices: - b.a.p cell receptors - a.m. cell receptors - er cell receptors - b cell receptors A:
A: b cell receptors
Question: Answer the following question given this paragraph: Chloroplasts capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food. Chloroplasts look like flat discs and are usually 2 to 10 micrometers in diameter and 1 micrometer thick. A model of a chloroplast is shown in Figure below . The chloroplast is enclosed by an inner and an outer phospholipid membrane. Between these two layers is the intermembrane space. The fluid within the chloroplast is called the stroma , and it contains one or more molecules of small, circular DNA. The stroma also has ribosomes. Within the stroma are stacks of thylakoids , sub-organelles that are the site of photosynthesis. The thylakoids are arranged in stacks called grana (singular: granum). A thylakoid has a flattened disk shape. Inside it is an empty area called the thylakoid space or lumen. Photosynthesis takes place on the thylakoid membrane. Q: What cell structures capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food? Choices: - fibroblasts - ribosomes - nuclei - chloroplasts A:
Answer: chloroplasts

Answer the following question given this paragraph: Comets are small, icy objects that orbit the Sun in very elliptical orbits. When they are close to the Sun, they form comas and tails, which glow and make the comet more visible. Q: What types of orbits do comets usually have? Choices: - vertical - convex - spectral - elliptical A:
(Answer)
elliptical
