Q: What catalyst substances may also allow reactions to occur by different pathways that have lower activation energy? Choices: - carbohydrates - hormones - calories - enzymes A:
enzymes
Answer the following question given this paragraph: The shore may have a lot of sediment washed from land or eroded from cliffs. The sediment is transported by currents. Q: How is sediment transported? Choices: - storms - landslides - winds - currents A:
currents
Q: Answer the following question given this paragraph: one degree Fahrenheit. Only 100 Celsius degrees span the same range as 180 Fahrenheit degrees, thus one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale 180 / 100 = 9 / 5. The Kelvin scale is the temperature scale that is commonly used in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points of water are 273.15 K and 373.15 K, respectively. Thus, the magnitude of temperature differences is the same in units of kelvins and degrees Celsius. Unlike other temperature scales, the Kelvin scale is an absolute scale. It is used extensively in scientific work because a number of physical quantities, such as the volume of an ideal gas, are directly related to absolute temperature. The kelvin is the SI unit used in scientific work. Q: Which temperature scale is commonly used in science? Choices: - ph scale - celsius - centigrade - kelvin scale A:
A: kelvin scale
Question: Answer the following question given this paragraph: Q: What type of cells in the body fluids and tissues of most animals specifically interact with and destroy pathogens? Choices: - Microglial cells - Dendritic cells - White blood cells - immune cells A:
Answer: immune cells

Answer the following question given this paragraph: Osmosis Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water. Osmosis is a special case of diffusion. Water, like other substances, moves from an area of higher concentration to one of lower concentration. Imagine a beaker with a semipermeable membrane, separating the two sides or halves (Figure 3.21). On both sides of the membrane, the water level is the same, but there are different concentrations on each side of a dissolved substance, or solute, that cannot cross the membrane. If the volume of the water is the same, but the concentrations of solute are different, then there are also different concentrations of water, the solvent, on either side of the membrane. Q: What is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane Choices: - nutrients - mirrors - Gravity - osmosis A:
**Answer**
osmosis
Answer the following question given this paragraph: Plants are multicellular eukaryotes with cell walls made of cellulose. Plant cells also have chloroplasts. In addition, plants have specialized reproductive organs. These are structures that produce reproductive cells. Male reproductive organs produce sperm, and female reproductive organs produce eggs. Male and female reproductive organs may be on the same or different plants. Q: What type of cells have chloroplasts? Choices: - simple cells - animal cells - human cells - plant cells A:
plant cells
