Answer the following question given this paragraph: Pesticides were designed to kill bothersome insects. However, sometimes these pesticides will stop working. A pesticide that has worked in the past may no longer kill a particular type of insect. This is due to the development of resistance in the population of insects. The development of resistance to pesticides is one example of microevolution, a small change in a population. Q: Resistance to pesticides in a population of insects is an example of what? Choices: - macroevolution - redistributions - extinction - microevolution A:
microevolution
Answer the following question given this paragraph: Getting the same result when an experiment is repeated is called replication. If research results can be replicated, it means they are more likely to be correct. Q: What is it called when you get the same result after repeating an experiment? Choices: - variable - control - initiation - replication A:
replication
Q: Answer the following question given this paragraph: Melting ice and grinding wood into sawdust are examples of physical changes. Q: Melting ice and grinding wood into sawdust are examples of what? Choices: - chemical changes - reversible changes - unpredictable changes - physical changes A:
A: physical changes
Question: Answer the following question given this paragraph: Many turtles are aquatic. They may live in the ocean or in fresh water. Other turtles are terrestrial and live on land. All lizards are terrestrial. Their habitats may range from deserts to rainforests. They may live in a range of places, from underground burrows to the tops of trees. Most snakes are terrestrial, but some are aquatic. Crocodilians live in and around swamps or bodies of water. The water may be fresh or salty, depending on the species of crocodilian. Q: Name the two types of water turtles live in. Choices: - arctic water and ice water - ocean water and sea water - river water and lake water - ocean water and fresh water A:
Answer: ocean water and fresh water

Answer the following question given this paragraph: Conduction is usually faster in liquids and certain solids than in gases. Materials that are good conductors of thermal energy are called thermal conductors . Metals are excellent thermal conductors. They have freely moving electrons that can transfer energy quickly and easily. That's why the metal pot in Figure above soon gets hot all over, even though it gains thermal energy from the fire only at the bottom of the pot. In Figure below , the metal heating element of the curling iron heats up almost instantly and quickly transfers energy to the strands of hair that it touches. Q: What are materials that are good conductors of thermal energy called? Choices: - reflective conductors - atmospheric conductors - geospatial conductors - thermal conductors A:
**Answer**
thermal conductors
Answer the following question given this paragraph: Figure 32.7 Pollen develops from the microspore mother cells. The mature pollen grain is composed of two cells: the pollen tube cell and the generative cell, which is inside the tube cell. The pollen grain has two coverings: an inner layer (intine) and an outer layer (exine). The inset scanning electron micrograph shows Arabidopsis lyrata pollen grains. (credit "pollen micrograph": modification of work by Robert R. Wise; scale-bar data from Matt Russell). Q: The mature pollen grain is composed of two cells: the pollen tube cell and which other cell? Choices: - ova - glial cell - photosynthesis cell - generative cell A:
generative cell
