Answer the following question given this paragraph: Unlike other tetrapod vertebrates (reptiles, birds, and mammals), amphibians do not produce amniotic eggs. Therefore, they must lay their eggs in water so they won't dry out. Their eggs are usually covered in a jelly-like substance, like the frog eggs shown in Figure below . The jelly helps keep the eggs moist and offers some protection from predators. Q: Unlike other tetrapod vertebrates (reptiles, birds, and mammals), amphibians do not produce what type of eggs? Choices: - epithelial - prokaryotic - umbilical - amniotic A:
amniotic
Answer the following question given this paragraph: If heated water is released into a body of water, it may cause thermal pollution. Thermal pollution is a reduction in the quality of water because of an increase in water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and factories. This water is heated and then returned to the natural environment at a higher temperature. Q: What happens when heated water is released into a body of water? Choices: - crystalline pollution - gaseous pollution - geysers - thermal pollution A:
thermal pollution
Q: Answer the following question given this paragraph: Minerals are made by natural processes. The processes that make minerals happen in or on the Earth. For example, when hot lava cools, mineral crystals form. Minerals also precipitate from water. Some minerals grow when rocks are exposed to high pressures and temperatures. Q: What is formed when hot lava cools? Choices: - hydrogen crystals - lava rock - magma crystals - mineral crystals A:
A: mineral crystals
Question: Answer the following question given this paragraph: Electromagnetic induction is the process of generating electric current with a magnetic field. It occurs whenever a magnetic field and an electric conductor move relative to one another so the conductor crosses lines of force in the magnetic field. Q: What is the process of generating electric current with a magnetic field? Choices: - mechanical induction - magnetic induction - electromagnetic ordination - electromagnetic induction A:
Answer: electromagnetic induction

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:
**Answer**
microevolution
Q: Answer the following question given this paragraph: 7.2 History of cell knowledge The optical microscope was first invented in 17th century. Shortly thereafter scientists began to examine living and dead biological tissues in order to better understand the science of life. Some of the most relevant discovery milestones of the time period include: The invention of the microscope11 , which allowed scientists for the first time to see biological cells Robert Hooke12 in 1665 looked at cork under a microscope and described what he called cork "cells" Anton van Leeuwenhoek13 called the single-celled organisms that he saw under the microscope "animalcules" Matthias Jakob Schleiden14 , a botanist, in 1838 determined that all plants consist of cells Theodor Schwann15 , a zoologist, in 1839 determined that all animals consist of cells Rudolf Virchow16 proposed the theory that all cells arise from previously existing cells In 1838, the botanist Matthias Jakob Schleiden and the physiologist Theodor Schwann discovered that both plant cells and animal cells had nuclei. Based on their observations, the two scientists conceived of the hypothesis that all living things were composed of cells. In 1839, Schwann published 'Microscopic Investigations on the Accordance in the Structure and Growth of Plants and Animals', which contained the first statement of their joint cell theory. Q: In what century was the microscope invented? Choices: - 20th - 16th - 15th - 17th A:
A: 17th
