1.A scientist conducting an experiment begins with the knowledge that mass is neither created nor destroyed during chemical reactions.

2.After a wet winter a botanist notices fungus on her Photinia shrub. She suggests that the shrub Photinia will develop a leaf fungus after winters with more than 25 cm of rain.

3.Scientists decide that after repeated standardized trials, that certain traits in peas are passed down from the parent plants. The scientists publish their findings in a journal.

4.Scientists take evidence from a variety of experiments to support the idea that atoms of different elements consist of different numbers of the same types of sub-atomic particles.

5.In his chemistry class Jim is investigating the chemical properties of metals. After watching calcium react with water, Jim makes an educated guess that all metals dissolve in water. A statement can match more than one description. Whoever answers first get brailest

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
