Answer the following question given this paragraph: Other bacteria are parasitic and can cause illness. In parasitism , the bacteria benefit, and the other organism is harmed. Harmful bacteria will be discussed in another concept. Q: What would you call a relationship where the bacteria benefit and and the other organism is harmed? Choices: - pathology - fungi - symbiotic - parasitism A:
parasitism
Answer the following question given this paragraph: Carbon is an element. Carbon is the basis of all life on Earth. Since carbon can combine with many other elements it forms a variety of different substances. Q: Which chemical element is the basis of all life on earth? Choices: - oxygen - nitrogen - hydrogen - carbon A:
carbon
Q: Answer the following question given this paragraph: When lactose is available, a lactose metabolite called allolactose binds to the allosteric site on the repressor. This interaction causes a conformational change in the repressor shape and the repressor falls off the operator, allowing RNA polymerase to bind to the promoter and initiate transcription. Allolactose is called an inducer because it turns on, or induces the expression of the lac genes. Q: Which inducer turns on the expression of the lac genes? Choices: - xerophyte - glucose - galactose - allolactose A:
A: allolactose
Question: Answer the following question given this paragraph: Q: Body plans do provide a succinct way to compare and contrast what? Choices: - degenerative animal features - missing animal features - distinctive animal features - key animal features A:
Answer: key animal features

Answer the following question given this paragraph: In the first beaker, distilled water does not conduct a current because water is a molecular compound. In the second beaker, solid sodium chloride also does not conduct a current. Despite being ionic and thus composed of charges particles, the solid crystal lattice does not allow the ions to move between the electrodes. Mobile charged particles are required for the circuit to be complete and the light bulb to light up. In the third beaker, the NaCl has been dissolved into the distilled water. Now the crystal lattice has been broken apart and the individual positive and negative ions can move. Cations move to one electrode, while anions move to the other, allowing electricity to flow (see Figure below ). Melting an ionic compound also frees the ions to conduct a current. Ionic compounds conduct an electric current when melted or dissolved in water. Q: In the first beaker, distilled water does not conduct a current because water is a what? Choices: - pure element - solute - magnetic compound - molecular compound A:
**Answer**
molecular compound
Answer the following question given this paragraph: The respiratory system is the body system that exchanges gases with the outside air. It brings air containing oxygen into the body for the cells. It also releases carbon dioxide from the cells into the air. This exchange of gases is called respiration. Q: Which system in the body exchanges gases with the outside air? Choices: - immune - digestive - vascular - respiratory A:
respiratory
