2. You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth p
lant receives pure water. After a two- week period, the height is measured. Independent: Dependent: Constants: Control: 3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. Independent: Dependent: Constants: Control: 4. Pea plant clones are given different amounts of water for a three-week period. The first pea plant receives 400 milliliters a day. The second pea plant receives 200 milliliters a day. The third pea plant receives 100 milliliters a day. The fourth pea plant does not receive any extra water: the plant only receives natural ways of receiving water. The heights of the pea plants are recorded daily. Independent: Dependent: Constants: Control: 5. One tank of goldfish is fed the normal amount of food once a day. A second tank is fed twice a day. A third tank is fed four times a day during a six week study. The fish’s weight is recorded daily. Independent: Dependent: Constants: Control: 7. You decide to clean the bathroom. You notice that the show is covered in a strange green slime. You try to get rid of this slime by adding lemonade juice. You spray half of the shower with lemonade juice and spray the other half of the shower with water. After 3 days of spraying equal amounts 3 times a day, there is no change in the appearance of the green slime on either side of the shower. Independent: Dependent: Constants: Control: 8. You want to test which size of soccer ball is easiest to juggle with your feet. You test a size 3, size 4, and size 5 ball. You count the seconds the ball stays in the air for each of the trials. You allow yourself to use both of your feet, knees, and head to juggle the ball. Independent: Dependent: Constants: Control: 9. Come up with and describe your own experiment. Note the Independent, Dependent and Control Variables, and whether your data will be Quantitative or Qualitative. Experiment: Independent: Dependent: Constants: Control: The first person answer that question i give brainliest answer this is urgent!!!!!
The theory of tectonic plates explains that large convectional currents occuring in the mantle(as a result of magma) are the reasons plates,and so continents,are moved. Note movement occurs in the boundary in between the plates.
Coprolites are the type of fossils which can tell the scientist what dinosaurs ate.
Explanation:
A Coprolites is fossilized faeces.They are classified as trace fossils as opposed to body fossils as they give evidence for the animal's behaviour rather than morphology.This name is derived from Greek words.They were first described by William Buckland in 1829.
