Ques: Answer the following question given this paragraph: Earthquakes at convergent plate boundaries mark the location of the subducting lithosphere. The motion of the lithosphere as it plunges through the mantle causes the quakes ( Figure below ). At greater depths, the plate heats up enough to deform plastically. Q: Earthquakes at convergent plate boundaries mark the location of the what? Choices: - abducting lithosphere - speeding lithosphere - shorting lithosphere - subducting lithosphere A:
Ans: subducting lithosphere

Ques: Answer the following question given this paragraph: Mitosis and meiosis are two types of cell division, with dramatically different products. Mitosis begins with a diploid somatic cell and ends with two genetically identical diploid cells. Meiosis begins with a diploid cell and produces four haploid genetically unique cells that form gametes. Q: Mitosis and meiosis are two types of what process, with dramatically different products? Choices: - cell transition - cell solution - cell diffusion - cell division A:
Ans: cell division

Ques: Answer the following question given this paragraph: During metamorphism, a rock may change chemically. Ions move in or out of a mineral. This creates a different mineral. The new minerals that form during metamorphism are more stable in the new environment. Extreme pressure may lead to physical changes. If pressure is exerted on the rock from one direction, the rock forms layers. This is foliation . If pressure is exerted from all directions, the rock usually does not show foliation. Q: If pressure is exerted on the rock from one direction, the rock forms layers. this is called what? Choices: - protonation - stratification - sedimentation - foliation A:
Ans: foliation

Ques: Answer the following question given this paragraph: Q: What can be switched off by a protein called the trp repressor? Choices: - the cytokine - the chaperone protein - the genetic precursor - the operon A:
Ans:
the operon
