True
A confounding variable is an “extra” variable that you didn’t account for. They can ruin an experiment and give you useless results. They can suggest there is correlation when in fact there isn’t. They can even introduce bias. That’s why it’s important to know what one is, and how to avoid getting them into your experiment in the first place.

Explanation:
Answer;
A. if water moves into a cell by osmosis it is moving into an area of higher solute concentration.
Explanation;
-Movement of water from a dilute to a more concentrated solution through a partially (semi) permeable membrane that allows the passage of water but not solute molecules is called osmosis.
-Osmosis describes the movement of water (not the solute) across a selectively permeable membrane until there is an equal concentration of water and solute on both sides of the membrane.
Answer:
Forms of fossils and there arrangement with layer of rock.
Explanation:
- The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks.
- The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.
C applies as the kidney must excrete salt in order to get rid of excess water. (Water chases salt) if there is too much salt in the body the urine will be much more concentrated then if the body had too much water. Glucose may kbly be excreted if there are problems with the kidney- some diabetics pee out glucose. D applies to some degree- salt will still be excreted but in very dilute amounts- as the water must chase something in order to be excreted.
