Answer the following question given this paragraph: Scientists have long wanted to find the most basic building blocks of the universe. They asked, "what are the fundamental particles of matter that cannot be subdivided into smaller, simpler particles," and "what holds these particles together?" The quest for fundamental particles began thousands of years ago. Scientists thought they had finally found them when John Dalton discovered the atom in 1803 (see the timeline in Table below ). The word atom means "indivisible," and Dalton thought that the atom could not be divided into smaller, simpler particles. Q: John dalton thought that what unit, which means "indivisible", could not be divided into smaller, simpler particles? Choices: - electron - nucleus - neutron - atom A:
atom
Answer the following question given this paragraph: Our Sun is a star. This star provides light and heat and supports almost all life on Earth. The Sun is the center of the solar system. It is by far the largest part of the solar system. Added together, all of the planets make up just 0.2 percent of the solar system's mass. The Sun makes up the remaining 99.8 percent of all the mass in the solar system ( Figure below )!. Q: What is the largest body in the solar system? Choices: - earth - asteroids - planet - sun A:
sun
Q: Answer the following question given this paragraph: How does the food you eat provide energy? When you need a quick boost of energy, you might reach for an apple or a candy bar. But cells do not "eat" apples or candy bars; these foods need to be broken down so that cells can use them. Through the process of cellular respiration , the energy in food is changed into energy that can be used by the body's cells. Initially, the sugars in the food you eat are digested into the simple sugar glucose , a monosaccharide . Recall that glucose is the sugar produced by the plant during photosynthesis. The glucose, or the polysaccharide made from many glucose molecules, such as starch , is then passed to the organism that eats the plant. This organism could be you, or it could be the organism that you eat. Either way, it is the glucose molecules that holds the energy. Q: Which molecules in the body holds energy? Choices: - mitochondria molecules - water molecules - lipid molecules - glucose molecules A:
A: glucose molecules
Question: Answer the following question given this paragraph: Scientists think that glycolysis evolved before the other stages of cellular respiration. This is because the other stages need oxygen, whereas glycolysis does not, and there was no oxygen in Earth's atmosphere when life first evolved about 3.5 to 4 billion years ago. Cellular respiration that proceeds without oxygen is called anaerobic respiration . Q: What do you call cellular respiration that does not need oxygen to proceed? Choices: - aerobic respiration - malolactic respiration - cellular breathing - anaerobic respiration A:
Answer: anaerobic respiration

Answer the following question given this paragraph: Some bacteria depend on a host organism for energy and nutrients. These bacteria are known as parasites . If the host starts attacking the parasitic bacteria, the bacteria release a layer of slime that surrounds the cell wall. This slime offers an extra layer of protection. Q: When a host attacks a parasitic bacteria, the bacteria release what to surround the cell wall? Choices: - bacteriophages - pathogens - protoplasma - layer of slime A:
**Answer**
layer of slime
Answer the following question given this paragraph: Some elements lose one or more electrons in forming ions. These ions are known as " cations " because they are positively charged and migrate toward the negative electrode ( cathode ) in an electrical field. Looking at the periodic table below, we know that the group 1 elements are all characterized by having one s electron in the outer orbit and group 2 elements have two s electrons in the outer orbit. These electrons are loosely attached to the atom and can easily be removed, leaving more protons in the atom that there are electrons, so the resulting ion has a positive charge. Cations can also be formed from electron loss to many of the transition elements. Q: What are electrons lost during the formation of ions called? Choices: - catalysts - oxides - isotopes - cations A:
cations
