Answer the following question given this paragraph: Cilia ( cilium , singular) are made up of microtubule containing extensions of the cell membrane. Although both cilia and flagella are used for movement, cilia are much shorter than flagella. Cilia cover the surface of some single-celled organisms, such as paramecium. Their cilia beat together to move the little animal-like protists through the water. In multicellular animals, including humans, cilia are usually found in large numbers on a single surface of cells. Multicellular animals' cilia usually move materials inside the body. For example, the mucociliary escalator of the respiratory system is made up of mucus-secreting ciliated cells that line the trachea and bronchi. These ciliated cells, shown in Figure below , move mucus away from the lungs. This mucus catches spores, bacteria, and debris and moves to the esophagus, where it is swallowed. Q: Cilia and flagella are generally associated with what function in organisms, whether the function is internal or external? Choices: - digestion - reproduction - sight - movement A:
(Answer)
movement
Ques: Answer the following question given this paragraph: Living things need nonliving matter as well as energy. What do you think matter is used for? One thing is to build bodies. They also need it to carry out the processes of life. Any nonliving matter that living things need is called a nutrient . Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. You can see how in Figure below . Q: What are the nonliving matter that living things need called? Choices: - fluids - elements - acids - nutrients A:
Ans: nutrients
(Q).
Answer the following question given this paragraph: Pressure Relationships Inspiration (or inhalation) and expiration (or exhalation) are dependent on the differences in pressure between the atmosphere and the lungs. In a gas, pressure is a force created by the movement of gas molecules that are confined. For example, a certain number of gas molecules in a two-liter container has more room than the same number of gas molecules. Q: Pressure relationships inspiration (or inhalation) and expiration (or exhalation) are dependent on the differences in pressure between the atmosphere and these? Choices: - salts - enzymes - bones - lungs A:
(A).
lungs
Ques:Answer the following question given this paragraph: Cleaning groundwater in an aquifer requires bioremediation or chemical remediation. Bioremediation uses microorganisms to consume a pollutant. Chemical remediation destroys the contaminant. Q: What do you call a process that uses microorganisms to consume a pollutant? Choices: - siltation - filtration - biodegradation - bioremediation A:

Ans:bioremediation

Q: When sparks from a steel grinder react with oxygen, what do they form? Choices: - rust - spontaneous combustion - steel oxide - iron oxide A:

Ans:
iron oxide
