Answer the following question given this paragraph: In addition to these organs, the male reproductive system consists of a series of ducts and glands. Ducts include the vas deferens and ejaculatory ducts. They transport sperm from the epididymis to the urethra in the penis. Glands include the seminal vesicles and prostate gland . They secrete substances that become part of semen. Q: The vas deferens and ejaculatory ducts are part of what system? Choices: - female adaptive system - female reproductive system - male circulatory system - male reproductive system A:
male reproductive system

Answer the following question given this paragraph: The sample in an experiment or other investigation consists of the individuals or events that are studied. Typically, the sample is much smaller than all such individuals or events that exist in the world. Whether the results based on the sample are true in general cannot be known for certain. However, the larger the sample is, the more likely it is that the results are generally true. Similarly, the more times that an experiment is repeated and the same results obtained, the more likely the results are valid. This is why scientific experiments should always be repeated. Q: What part of an experiment or other investigation consists of the individuals or events that are studied? Choices: - hypothesis - experimental control - independent variable - sample A:
(Answer)
sample
Ques: Answer the following question given this paragraph: Oxygen has the second highest electronegativity of any element; consequently, it prefers to share or accept electrons from other elements. Only with fluorine does oxygen form compounds in positive oxidation states. Q: Oxygen has the second highest electronegativity of any element; consequently, it prefers to share or accept electrons from other elements. only with fluorine does oxygen form compounds in this? Choices: - liquid oxidation states - chemical oxidation states - negative Oxidation States - positive oxidation states A:
Ans: positive oxidation states

Ques:Answer the following question given this paragraph: In some ways, a collection of gas molecules represents the simplest form of matter. Because the individual molecules are so far apart, they have only fleeting interactions with one another. In contrast, molecules that have clustered together to form a liquid or solid are constantly exerting forces on each other. In fact, it is only because of these attractive forces that molecular solids and liquids exist at all. In this lesson, we will look at some of the ways in which molecules and ions attract one another to form solids and liquids. Q: In some ways, a collection of gas molecules represents the simplest form of what? Choices: - life - energy - protein - matter A:

Ans:matter
Answer the following question given this paragraph: Irrigation is the single biggest use of water. Overhead irrigation wastes a lot of water. Drip irrigation wastes a lot less. Figure below shows a drip irrigation system. Water pipes run over the surface of the ground. Tiny holes in the pipes are placed close to each plant. Water slowly drips out of the holes and soaks into the soil around the plants. Very little of the water evaporates or runs off the ground. Q: Does overhead irrigation or drip irrigation use less water? Choices: - mist irrigation - stream irrigation - constant flow - drip irrigation A:
drip irrigation
