Answer the following question given this paragraph: Clouds form when water vapor condenses around particles in the air. The particles are specks of matter, such as dust or smoke. Billions of these tiny water droplets come together to make up a cloud. If the air is very cold, ice crystals form instead of liquid water. Q: What forms when water vapor condenses around particles in the air? Choices: - wind - storms - humididty - clouds A:
clouds

Answer the following question given this paragraph: Q: What substances are secreted by specialized cells usually located in endocrine glands? Choices: - lipids - protein - acid - hormones A:
(Answer)
hormones
Ques: Answer the following question given this paragraph: Planets are held in their orbits by the force of gravity. What would happen without gravity? Imagine that you are swinging a ball on a string in a circular motion. Now let go of the string. The ball will fly away from you in a straight line. It was the string pulling on the ball that kept the ball moving in a circle. The motion of a planet is very similar to the ball on a string. The force pulling the planet is the pull of gravity between the planet and the Sun. Q: What force holds planets in their orbits? Choices: - magnetism - centrifuge - Big Bang - gravity A:
Ans: gravity
(Q).
Answer the following question given this paragraph: Soil formation requires weathering. Where there is less weathering, soils are thinner. However, soluble minerals may be present. Where there is intense weathering, soils may be thick. Minerals and nutrients would have been washed out. Soil development takes a very long time. It may take hundreds or even thousands of years to form the fertile upper layer of soil. Soil scientists estimate that in the very best soil forming conditions, soil forms at a rate of about 1mm/year. In poor conditions, it may take thousands of years!. Q: What slow process is required for formation of soil? Choices: - leaching - digestion - fossilization - weathering A:
(A).
weathering
Ques:Answer the following question given this paragraph: Bundles of vascular tissue run through the ground tissue of a stem and transport fluids. Plants may vary in how these bundles are arranged. Q: What population on earth is already harming the environment due to less resources to go around? Choices: - whales - rats - insects - humans A:

Ans:humans
Question: Answer the following question given this paragraph: 22.4 Bacterial Diseases in Humans Devastating diseases and plagues have been among us since early times. There are records about microbial diseases as far back as 3000 B. Infectious diseases remain among the leading causes of death worldwide. Emerging diseases are those rapidly increasing in incidence or geographic range. They can be new or re-emerging diseases (previously under control). Many emerging diseases affecting humans, such as brucellosis, are zoonoses. The WHO has identified a group of diseases whose re-emergence should be monitored: Those caused by bacteria include bubonic plague, diphtheria, and cholera. Biofilms are considered responsible for diseases such as bacterial infections in patients with cystic fibrosis, Legionnaires' disease, and otitis media. They produce dental plaque; colonize catheters, prostheses, transcutaneous, and orthopedic devices; and infect contact lenses, open wounds, and burned tissue. Biofilms also produce foodborne diseases because they colonize the surfaces of food and food-processing equipment. Biofilms are resistant to most of the methods used to control microbial growth. The excessive use of antibiotics has resulted in a major global problem, since resistant forms of bacteria have been selected over time. A very dangerous strain, methicillin-resistant Staphylococcus aureus (MRSA), has wreaked havoc recently. Foodborne diseases result from the consumption of contaminated food, pathogenic bacteria, viruses, or parasites that contaminate food. Q: What results from the consumption of pathogenic bacteria, viruses, or parasites that contaminate food? Choices: - airborne diseases - parabens diseases - hidebound diseases - foodborne diseases A:
Answer:
foodborne diseases
