Is a virus considered living? Say why or why not and defend your answer.

A class tests two fertilizers. Group A’s plants grow 5 cm taller than Group B’s. What would we say, using CER, to explain their experiment?
Claim = Fertilizer A is better. Evidence = Plants in Group A grew 5 cm taller. Reasoning = Fertilizer A provided more nutrients, which improved plant growth.
Name one difference between a scanning electron microscope (SEM) and a transmission electron microscope (TEM).
SEM = 3D surface images; TEM = detailed internal images.
Explain how growth and development are different.
Growth = increase in size, so Cells are multiplying
Development = changes in form/function (ie: tadpole becoming an adult frog)
A scientist discovers a new organism that moves, eats, and reproduces...but it has no cells, is it alive? Defend your Answer
Open to defense
