Answer the following question given this paragraph: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. Q: Cutting forests and clearing land has also increased the amount of what in the atmosphere? Choices: - oxygen - smog - pesticides - carbon dioxide A:
(Answer)
carbon dioxide
Ques: Answer the following question given this paragraph: Inside the plasma membrane of prokaryotic cells is the cytoplasm. It contains several structures, including ribosomes, a cytoskeleton, and genetic material. Ribosomes are sites where proteins are made. The cytoskeleton helps the cell keep its shape. The genetic material is usually a single loop of DNA. There may also be small, circular pieces of DNA, called plasmids . (see Figure below ). The cytoplasm may contain microcompartments as well. These are tiny structures enclosed by proteins. They contain enzymes and are involved in metabolic processes. Q: A flower's colors come from what part of the plant? Choices: - glycogen - Petiole - Internode - vacuole A:
Ans: vacuole
(Q).

(A).
terrestrial
Ques:Answer the following question given this paragraph: All matter is made of tiny particles. Protons, neutrons, and electrons form atoms that bond together to create molecules. Atoms are the smallest units that have the properties of an element. Molecules are the smallest units of a compound. Chemical bonds hold molecules together. Molecules form the different types of minerals. The silicates make up most of Earth's crust. Minerals come together to create the three major rock types. They are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma. Sedimentary rocks form from compacted or cemented sediments. Metamorphic rocks are those that have been altered by heat and pressure. These three rock types are the material part of the rock cycle. They are connected by different processes. Different processes convert any type of rock into any other type of rock. These processes are weathering and erosion, crystallization, and burial and pressure, among others. Each rock contains a story of how it formed. For most rocks it is possible to know what it formed from. Q: The smallest units of matter that retain the unique properties of an element are known as what? Choices: - protons - molecules - neutrons - atoms A:

Ans:atoms
Ques:Answer the following question given this paragraph: Q: Animal cells grow mainly by synthesizing protein-rich cytoplasm, a process that is described as expensive in what way? Choices: - calorically - synthetically - time spent - metabolically A:

Ans:
metabolically
