Biology Quiz 7

Urease was the First Crystalline Enzyme and the Proof That Enzymes Are Proteins. The isolation and crystallization of urease by James Sumner, in 1926, provided a breakthrough in early enzyme studies.

Biological control is the use of living organisms to maintain pest populations below damaging levels. Predators of a pest, Pheromone traps and neem extracts are used as a Biological control. Pesticides are not used as a Biological control as it is a chemical agents.

Hypothermia occurs in human beings. It occurs when the human body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6°F (37°C). Hypothermia occurs as temperature falls below 95°F (35°C).

Atherosclerosis is a narrowing or blockage of artery walls usually caused by the buildup of fatty material called plaque. Coronary artery disease is a narrowing or blockage of coronary arteries. Hypertension, also known as low blood pressure, increases the risk of a heart attack. Hypotension (or low blood pressure) is a blood pressure under 90/60 mm/Hg.

An enzyme-linked immunosorbent assay, also called ELISA or EIA, is a test that detects and measures antibodies in your blood.

Zymase is a complex enzyme whose presence in glucose and fructose is converted into alcohol. It catalyzes the fermentation of sugar into ethanol and carbon dioxide.

Animal protein is called first-class protein because it is rich in essential amino acids. It is superior to plant protein because animal proteins contain a broad spectrum of amino acids with more vitamins and minerals than plant proteins.

Cytology is the study of cells as fundamental units of living things. A cytology test is used to look closely at cells and body fluids.

Jellyfish are marine invertebrates with no brains, no bones, no heart, and no eyes. Silverfish (Lepisma saccharinum) is not a fish but an insect.

Fructose is natural sugar present in fruits, certain vegetables, and honey. Grapes, apples, watermelon, asparagus, jackfruit, pears and zucchini are some fruits which contain high fructose.
