Answer the following question given this paragraph: How often do you think you see an arthropod? Well, have you ever looked up close at an ant? A spider? A fly? A moth? With over a million described species (and many more yet to be described) in the phylum containing arthropods, chances are, you encounter one of these organisms every day, without even leaving your house. Arthropods are a very diverse group of animals. In fact, they are the biggest group of animals on the planet, with upwards of 5 million distinct species. Q: What is the biggest group of animals on the planet? Choices: - herbivores - mammles - carnivores - arthropods A:
arthropods

Answer the following question given this paragraph: The warm, humid climate of the early Cambrian allowed life to expand and diversify. This brought the Cambrian Explosion. Life exploded both in diversity and in quantity!. Q: What allowed life to expand and diversify during the early cambrian period? Choices: - hot, dry climate - cool, dry climate - cool, humid climate - warm, humid climate A:
(Answer)
warm, humid climate
Ques: Answer the following question given this paragraph: Denaturation and Protein Folding Each protein has its own unique sequence and shape that are held together by chemical interactions. If the protein is subject to changes in temperature, pH, or exposure to chemicals, the protein structure may change, losing its shape without losing its primary sequence in what is known as denaturation. Denaturation is often reversible because the primary structure of the polypeptide is conserved in the process if the denaturing agent is removed, allowing the protein to resume its function. Sometimes denaturation is irreversible, leading to loss of function. One example of irreversible protein denaturation is when an egg is fried. The albumin protein in the liquid egg white is denatured when placed in a hot pan. Not all proteins are denatured at high temperatures; for instance, bacteria that survive in hot springs have proteins that function at temperatures close to boiling. The stomach is also very acidic, has a low pH, and denatures proteins as part of the digestion process; however, the digestive enzymes of the stomach retain their activity under these conditions. Protein folding is critical to its function. It was originally thought that the proteins themselves were responsible for the folding process. Only recently was it found that often they receive assistance in the folding process from protein helpers known as chaperones (or chaperonins) that associate with the target protein during the folding process. They act by preventing aggregation of polypeptides that make up the complete protein structure, and they disassociate from the protein once the target protein is folded. Q: An example of irreversible denaturation of what substance occurs to the liquid albumin when an egg is fried? Choices: - bacterial - acids - liquid - protein A:
Ans: protein

Answer the following question given this paragraph: Secondary succession occurs in a formerly inhabited area that was disturbed. Soil is already in place, so pioneer species include small plants such as grasses. Q: What occurs in a formerly inhabited area that was disturbed? Choices: - spontaneous mutation - mass extinction - natural selection - secondary succession A:
(A).
secondary succession
Ques:Answer the following question given this paragraph: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide, and large amounts of corrosive sulfuric acid! Scientists think the color of sunlight on Venus is reddish-brown. Q: What are clouds on earth made of? Choices: - rain - ozone - carbon dioxide gas - water vapor A:

Ans:water vapor
Question: Answer the following question given this paragraph: The pond on the left is covered with algae because there is too much nitrogen in the water. The red-shaded area in the map on the right is a dead zone in the Gulf of Mexico. It's called the hypoxic ("low oxygen") zone in the figure. Q: What does hypoxic mean? Choices: - standard oxygen level - Oxygen rate - higher oxygen - low oxygen A:
Answer:
low oxygen
