Ques: Answer the following question given this paragraph: Q: Many plants generate root pressure during which phase? Choices: - flowering season - developing season - end of life cycle - growing season A:
Ans: growing season

Ques: Answer the following question given this paragraph: All vertebrate organisms are in the phylum Chordata. Invertebrates, which make up about 95% (or more) of the animal kingdom, are divided into over 30 different phyla, some of which are listed below ( Table below ). Numerous invertebrate phyla have just a few species; some have only one described species, yet these are classified into separate phyla because of their unique characteristics. For example, sponges, with pores throughout their body, are from the phylum Porifera. Crabs and lobsters, with jointed appendages, are from the phylum Arthropoda. Q: Which phylum are all vertebrate organisms a member of? Choices: - pylum protozoa - phylum hominid - phylum arthropod - phylum chordata A:
Ans: phylum chordata

Ques: Answer the following question given this paragraph: Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone. Q: What does cartilage lack compared to bones, making it softer and less rigid? Choices: - potassium - magnesium - protein - calcium A:
Ans: calcium

Ques: Answer the following question given this paragraph: Some metals, such as gold and platinum, do not corrode easily because they are very resistant to oxidation by common substances. Some other metals begin to be oxidized, but are further protected from additional corrosion by a coating formed on the surface. Aluminum reacts with oxygen to form aluminum oxide, which remains tightly packed on the surface. The aluminum oxide prevents the interior of the aluminum from corroding. Not all corrosion is a result of reaction with oxygen. Copper corrodes by reaction with carbon dioxide to form copper(II) carbonate. This distinctive green compound is also called patina and prevents the copper underneath from further corrosion (see Statue of Liberty in the Figure below ). Q: Some metals, such as gold and platinum, do not corrode easily because they are very resistant to what? Choices: - evaporation - precipitation - heat - oxidation A:
Ans:
oxidation
