Answer the following question given this paragraph: Cell Structure The cells of protists are among the most elaborate of all cells. Most protists are microscopic and unicellular, but some true multicellular forms exist. A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism. Still other protists are composed of enormous, multinucleate, single cells that look like amorphous blobs of slime, or in other cases, like ferns. In fact, many protist cells are multinucleated; in some species, the nuclei are different sizes and have distinct roles in protist cell function. Single protist cells range in size from less than a micrometer to three meters in length to hectares. Protist cells may be enveloped by animal-like cell membranes or plant-like cell walls. Others are encased in glassy silica-based shells or wound with pellicles of interlocking protein strips. The pellicle functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion. Q: What functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion? A:
****
A: pellicle

Problem:OPTIONS:
- electrolysis
- phototropism
- biosynthesis
- chemosynthesis

Answer the following question given this paragraph: There are also bacteria that use chemical processes to produce food. They get their energy from sources other than the sun, but they are still called producers. This process is known as chemosynthesis , and is common in ecosystems without sunlight, such as certain marine ecosystems. Q: What is the process in which producers get their energy from sources other than the sun? A:
****
A: chemosynthesis

Problem:OPTIONS:
- inertia
- mechanical energy
- residual energy
- kinetic energy

Answer the following question given this paragraph: The energy of motion is kinetic energy, KE. Whenever an object is in motion it has kinetic energy. The faster it is going, the more energy it has. Q: What is the term for the energy of motion, which is exhibited by the speed of an object? A:
****
A: kinetic energy

Problem:OPTIONS:
- temperature
- weight
- velocity
- pressure

Answer the following question given this paragraph: The value of , the ideal gas constant, depends on the units chosen for pressure, temperature, and volume in the ideal gas equation. It is necessary to use Kelvin for the temperature and it is conventional to use the SI unit of liters for the volume. However, pressure is commonly measured in one of three units: kPa, atm, or mmHg. Therefore, can have three different values. Q: What are kpa, atm, and mmhg measurement units for? A:
****
A:
pressure
