Ques: Q: What hormone does the endocrine system secrete to help cells absorb blood sugar? Read this paragraph and choose the correct option from the provided answers: After you eat and digest a sugary snack, the level of sugar in your blood quickly rises. In response, the endocrine system secretes the hormone insulin. Insulin helps cells absorb sugar from the blood. This causes the level of sugar in the blood to fall back to its normal level. Choices: - glucose - testosterone - Cortisol - insulin A:
Ans: insulin

Ques: Q: What is the term for proportion of amount of product actually produced in a chemical reaction versus predicted amount ? Read this paragraph and choose the correct option from the provided answers: Chemical reactions in the real world don't always go exactly as planned on paper. In the course of an experiment, many things will contribute to the formation of less product than would be predicted. Besides spills and other experimental errors, there are usually losses due to an incomplete reaction, undesirable side reactions, etc. Chemists need a measurement that indicates how successful a reaction has been. This measurement is called the percent yield. Choices: - calculus yield - decrease yield - percent impact - percent yield A:
Ans: percent yield

Ques: Q: How does the heart transport blood? Read this paragraph and choose the correct option from the provided answers: A screw is an inclined plane wrapped around a cylinder. When on a screw, inclined planes are called threads, which can be seen in the image above. The mechanical advantage of a screw increases with the density of the threads. The calculations to determine the IMA for a screw involve the circumference of the head of the screw and the thread width. When the screw is turned completely around one time, the screw penetrates by one thread width. So, if the circumference of the head of a screw is 3.0 cm and the thread width is 0.60 cm, then the IMA would be calculated by. Choices: - blood pellets - nerves - muscles - blood vessels A:
Ans: blood vessels

Ques: Q: Spores are the basic reproductive units of what organism? Read this paragraph and choose the correct option from the provided answers: Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body , which is the part of the fungus that produces spores ( Figure below ). The spores are the basic reproductive units of fungi. The mycelium remains hidden until it develops one or more fruiting bodies. Choices: - mushrooms - yeast - tropical plants - fungi A:
Ans:
fungi
