Answer the following question given this paragraph: Scientists are using telescopes to search for other planets that may have conditions favorable for life. The places they can look are near our solar system in our galaxy. Q: What do scientists use to search other planets suitable for living? Choices: - optics - lasers - microscopes - telescopes A:
(Answer)
telescopes
Ques: Answer the following question given this paragraph: Some of the best known types of fungi are mushrooms, which can be edible or poisonous ( Figure below ). Many species are grown commercially, but others are harvested from the wild. When you order a pizza with mushrooms or add them to your salad, you are most likely eating Agaricus bisporus , known as white or button mushrooms, the most commonly eaten species. Other mushroom species are gathered from the wild for people to eat or for commercial sale. Many mushroom species are poisonous to humans. Some mushrooms will simply give you a stomachache, while others may kill you. Some mushrooms you can eat when they are cooked but are poisonous when raw. So if you find mushrooms in the wild, don't eat them until you are certain they are safe!. Q: Mushrooms are an example of what type of organism, which includes beneficial and toxic specimens? Choices: - spores - bacteria - seeds - fungi A:
Ans: fungi

Answer the following question given this paragraph: Ionic substances are completely held together by ionic bonds. The full charges of the ions (for example, Na + and Cl - in sodium chloride) cause electrostatic interactions that result in a stable crystal lattice. We saw in the previous chapter that most ionic compounds have high melting points, are brittle, are often soluble in water, and conduct electricity when melted or dissolved in water. Ionic compounds exist as extended, orderly arrangements of ions. As we will see, this is quite different from the structure of molecular substances, which take the form of collections of individual molecules. The atoms within a molecule are held very strongly together, but the interactions between different molecules are significantly weaker. Q: What are ionic substances completely held together by? Choices: - thermal bonds - localized bonds - magnetic bonds - ionic bonds A:
(A).
ionic bonds
Ques:Answer the following question given this paragraph: Fossils of ocean animals are found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils show that the area was once at the bottom of a sea. The seabed was later uplifted to form the Himalaya mountain range. An example is shown in the Figure below . Q: What evidence is there that mt. everest was once at the bottom of a sea? Choices: - skulls - corals - glaciers - fossils A:

Ans:fossils
Question: Answer the following question given this paragraph: There are some noticeable spikes on the BE / A graph, which represent particularly tightly bound nuclei. These spikes reveal further details of nuclear forces, such as confirming that closed-shell nuclei (those with magic numbers of protons or neutrons or both) are more tightly bound. The spikes also indicate that some nuclei with even numbers for Z and N , and with Z = N , are exceptionally tightly bound. This finding can be correlated with some of the cosmic abundances of the elements. The most common elements in the universe, as determined by observations of atomic spectra from outer space, are hydrogen, followed by 4 He , with much smaller amounts of 12 C and other elements. It should be noted that the heavier elements are created in supernova explosions, while the lighter ones are produced by nuclear fusion during the normal life cycles of stars, as will be discussed in subsequent chapters. The most common elements have the most tightly bound nuclei. It is also no accident that one of the most tightly bound light nuclei is 4 He , emitted in decay. Q: The most common elements have the most tightly bound __________. Choices: - quarks - membrane - atoms - nuclei A:
Answer:
nuclei
