Answer the following question given this paragraph: Types of organisms that make glucose by photosynthesis are pictured in Figure below . They include plants, plant-like protists such as algae, and some kinds of bacteria. Living things that make glucose are called autotrophs ("self feeders"). All other living things obtain glucose by eating autotrophs (or organisms that eat autotrophs). These living things are called heterotrophs ("other feeders"). Q: What are living things that obtain glucose by eating self feeders called? Choices: - producers - chimeras - viruses - heterotrophs A:
heterotrophs

Answer the following question given this paragraph: The mass number is the number of protons plus the number of neutrons in an atom. For example, most atoms of helium have 2 neutrons, so their mass number is 2 + 2 = 4. This mass number means that an atom of helium has a mass of about 4 amu. Q: What makes up the mass number of an atom? Choices: - electrons and neutrons - atoms and neutrons - molecules and electrons - protons and neutrons A:
(Answer)
protons and neutrons
Ques: Answer the following question given this paragraph: Neutron stars are the corpses of stars left over after supernova explosions. They are the size of a small city, but can spin several times per second. (Try to imagine this in your head. ) Consider a neutron star of radius 10 km that spins with a period of 0.8 seconds. Imagine a person is standing at the equator of this neutron star. Calculate the centripetal acceleration of this person and compare it to the acceleration due to gravity on Earth. Q: Neutron stars are the corpses of left over what? Choices: - planet explosions - gravitational explosions - stellar explosions - supernova explosions A:
Ans: supernova explosions
(Q).
Answer the following question given this paragraph: Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge. Q: Which law refers to the electron charge remaining the same during transfer? Choices: - law of construct of charge - law of change - law of conservation of speculation - law of conservation of charge A:
(A).
law of conservation of charge
Ques:Answer the following question given this paragraph: A: The main ingredient of mothballs is the hydrocarbon naphthalene. The main ingredient in nail polish remover is the hydrocarbon acetone. The lawn mower runs on a mixture of hydrocarbons called gasoline, and the camp stove burns a hydrocarbon fuel named isobutane. Q: What is the main ingredient of mothballs? Choices: - stable naphthalene - processed naphthalene - ionized naphthalene - hydrocarbon naphthalene A:

Ans:hydrocarbon naphthalene
Ques:Answer the following question given this paragraph: When you look at the Moon from Earth, you notice dark and light areas. The maria are dark, solid, flat areas of lava. Maria covers around 16% of the Moon's surface, mostly on the near side. The maria formed about 3.0 to 3.5 billion years ago, when the Moon was continually bombarded by meteorites ( Figure below ). Large meteorites broke through the Moon's newly formed surface. This caused magma to flow out and fill the craters. Scientists estimate volcanic activity on the Moon ended about 1.2 billion years ago. Q: Covering about 16 percent of the moon's surface, maria are dark, solid, flat areas consisting of what substance? Choices: - debris - ash - dust - lava A:

Ans:
lava
