They probably evolved when some prokaryotic cells invaded or were engulfed by others. Q: What is thought to be the oldest eukaryotes? Choices: - amoebas - prokaryotes - arthropods - protists A:
Ans: protists

Ques: Answer the following question given this paragraph: a small scrap of paper onto a droplet of water, the paper floats on top of the water droplet, although the object is denser (heavier) than the water. This occurs because of the surface tension that is created by the water molecules. Cohesion and surface tension keep the water molecules intact and the item floating on the top. It is even possible to "float" a steel needle on top of a glass of water if you place it gently, without breaking the surface tension (Figure 2.11). Q: What causes a small scrap of paper placed on top of the water droplet to float , although the object is denser (heavier) than the water? Choices: - diffusion - transfusion - van der waals force - surface tension A:
Ans: surface tension

Ques: Answer the following question given this paragraph: The composition of the magma determines if the rock is mafic, felsic, or intermediate. Q: The composition of the magma determines if the rock is mafic, felsic, or what? Choices: - porous - magnetic - variable - intermediate A:
Ans: intermediate

Choices: - ice - carbon dioxide - magma - liquid water A:
