Answer the following question given this paragraph: Figure 11.7 Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. Q: Meiosis and mitosis are both preceded by one round of what? Choices: - internal fertilization - germination - cellular respiration - dna replication A:
dna replication

Answer the following question given this paragraph: If the first three are true but not the fourth, then that object is a dwarf planet . We now call Pluto a dwarf planet. There are other dwarf planets in the solar system. They are Eris, Ceres, Makemake and Haumea. There are many other reasons why Pluto does not fit with the other planets in our solar system. Q: What is pluto now called? Choices: - asteroid - planet - meteor - dwarf planet A:
(Answer)
dwarf planet
Ques: Answer the following question given this paragraph: The atmosphere contains small amounts of carbon dioxide. Climatologists have found that humans are putting a lot of extra carbon dioxide into the atmosphere. This is mostly from burning fossil fuels. The extra carbon dioxide traps heat from the Sun. Trapped heat causes the atmosphere to heat up. We call this global warming ( Figure below ). Q: Which gas is responsible for global warming? Choices: - oxygen - hydrocarbons - ozone - carbon dioxide A:
Ans: carbon dioxide

Answer the following question given this paragraph: Christopher Auyeung. Gas particles move randomly in all directions . CC BY-NC 3.0. Q: Gas particles can move randomly in what directions? Choices: - one direction - few directions - some directions - all directions A:
(A).
all directions
Ques:Answer the following question given this paragraph: The 1,000 or so species of cartilaginous fish are subdivided into two subclasses: the first includes sharks, rays, and skates; the second includes chimaera, sometimes called ghost sharks. Fish from this group range in size from the dwarf lanternshark, at 6.3 inches, to the over 50-foot whale shark. Sharks obviously have jaws, as do the other cartilaginous fish. These fish evolved from the jawless fish. So why did fish eventually evolve to have jaws? Such an adaptation would allow fish to eat a much wider variety of food, including plants and other organisms. Q: What is another term for ghost sharks? Choices: - anascea - litoria - aurea - chimaera A:

Ans:chimaera
Ques:Answer the following question given this paragraph: The force of friction between these two blocks is related to two factors. The first factor is the roughness of the surfaces that are interacting, which is called the coefficient of friction , (Greek letter mu). The second factor is the magnitude of the force pushing the top block down onto the lower block. It is reasonable that the more forcefully the blocks are pushed together, the more difficult it will be for one to slide over the other. The force pushing these blocks together is the result of gravity acting on the top block and pressing it against the bottom block, which resists the weight with an equal and opposite force called the normal force . The force of friction can be calculated by. Q: The roughness of interacting surfaces and the magnitude of force pushing one object onto another are two factors related to what force? Choices: - energy - tension - temperature - friction A:

Ans:
friction
