oxygen is given off during photosynthesis as a waste product
Explanation:
this is something that only plants and some algae and bacteria can do. they take sunlight and combined C02 and H20. they create glucose (C6H1206) and oxygen gas (02).
Answer:
Permineralization.
Explanation:
Fossils is the marks or part of body left of the organisms when they were alive. It is remains of the organisms on the land. Scientists collect these fossils to study about the different creatures that were once present in the earth. The process of collecting and fossilization is called permineralization.
Answer: B
Condensation is a process via which a liquid directly converts to a gaseous state, skipping the liquid state altogether. Therefore, a very cloudy sky is an example of water being converted to gaseous state directly.
Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
<u>Reason behind , why plastic base becomes negatively charged -:</u> When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
<u>Reason behind , why the metal cup does not become charged -:</u> The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .
Answer: D
Explanation: It would be D because it has a larger amount and all species vary and leaves can be exactly the same they change color and evolve into different shapes
