Joshi is investigating how much a spring stretches when different masses areadded. During the investigation, Joshi must do all of the following to keep himself safe EXCEPT? wear goggles clamp base to bench wear protective shoe look through the retort stand20. Complete these sentences.For safety, wires are covered with materials that do not conduct electricity.The wires are covered with ............................................ plastic insulator copper metal21. Sara and Juan are investigating the distance seeds can be dispersed.Here is the equipment they use.Sara drops a seed near the fan.Juan measures the distance the seed moves.They repeat the test for five more seeds.Here are their results. These seeds have all been dispersed by the same method.Pick the correct method. self dispersal explosive dispersal wind dispersal water dispersal animal dispersal22. A flounder is a flatfish that lives on the bottom of the sea. One of the options is NOT an explanation of the feature that you can see in the drawing which makes the fish suited to live on the sea-bed. flat: hide from predators fin: to swim easily mottled skin: for camouflage / hide from predators eyes above: see better23.
