Q: What are resources that can not be remade, or would take too long to remake to keep up wiht human use called? Read this paragraph and choose the correct option from the provided answers: Nonrenewable resources are natural resources that can't be remade or else take too long to remake to keep up with human use. Examples of nonrenewable resources are coal, oil, and natural gas, all of which are fossil fuels. Fossil fuels form from the remains of plants and animals over hundreds of millions of years. We are using them up far faster than they can be replaced. At current rates of use, oil and natural gas will be used up in just a few decades, and coal will be used up in a couple of centuries. Choices: - renewable resources - green resources - photoreactive resources - nonrewable resources A:
nonrewable resources

Q: The boiling points of liquid also correlate to the strength of which forces? Read this paragraph and choose the correct option from the provided answers: The boiling points of liquid also correlate to the strength of the intermolecular forces. Recall that diethyl ether has weak dispersion forces, which meant that the liquid has a high vapor pressure. The weak forces also mean that it does not require a large an input of energy to make diethyl ether boil and so it has a relatively low normal boiling point of 34.6C. Water, with its much stronger hydrogen bonding, has a low vapor pressure and a higher normal boiling point of 100C. Choices: - centrifugal - supramolecular - gravitational - intermolecular A:
intermolecular

Q: Q: Who is said to have dropped two objects of different masses from the tower of pisa? Read this paragraph and choose the correct option from the provided answers: Galileo's Experiment Galileo is said to have dropped two objects of different masses from the Tower of Pisa. He measured how long it took each to reach the ground. Since stopwatches weren't readily available, how do you think he measured their fall time? If the objects were the same size, but with different masses, what do you think he should have observed? Would this result be different if done on the Moon? PhET Explorations: Masses & Springs A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring. Choices: - darwin - copernicus - newton - galileo A:
A: galileo

Question: Q: What type of cell layer do flatworms have? Read this paragraph and choose the correct option from the provided answers: Flatworms have a mesoderm cell layer and simple organ systems. They also show cephalization and bilateral symmetry. Choices: - epidermis - cuticle - endoderm - mesoderm A:
Answer: mesoderm

Q: What term is used to describe organelles that are found only in animal cells? Read this paragraph and choose the correct option from the provided answers: Centrioles are organelles that are found only in animal cells. They are located near the nucleus. They help organize the DNA in the nucleus before cell division takes place. They ensure that the DNA divides correctly when the cell divides. Choices: - anticlines - fibrils - acids - centrioles A:
**Answer**
centrioles

Q: What forms as a result of decomposition when n2o is heated? Read this paragraph and choose the correct option from the provided answers: The oxides of nitrogen(III), nitrogen(IV), and nitrogen(V) react with water and form nitrogen-containing oxyacids. Nitrogen(III) oxide, N2O3, is the anhydride of nitrous acid; HNO2 forms when N2O3 reacts with water. There are no stable oxyacids containing nitrogen with an oxidation state of 4+; therefore, nitrogen(IV) oxide, NO2, disproportionates in one of two ways when it reacts with water. In cold water, a mixture of HNO2 and HNO3 forms. At higher temperatures, HNO3 and NO will form. Nitrogen(V) oxide, N2O5, is the anhydride of nitric acid; HNO3 is produced when N2O5 reacts with water: N 2 O 5(s) + H 2 O(l) 2HNO 3(aq) The nitrogen oxides exhibit extensive oxidation-reduction behavior. Nitrous oxide resembles oxygen in its behavior when heated with combustible substances. N2O is a strong oxidizing agent that decomposes when heated to form nitrogen and oxygen. Because one-third of the gas liberated is oxygen, nitrous oxide supports combustion better than air (one-fifth oxygen). A glowing splinter bursts into flame when thrust into a bottle of this gas. Nitric oxide acts both as an oxidizing agent and as a reducing agent. For example: oxidizing agent: P 4(s) + 6NO(g) P 4 O 6(s) + 3N 2(g). Choices: - ammonia and nitrogren - nitrogen and hydrogen - calcium and oxygen - nitrogen and oxygen A:
nitrogen and oxygen
