Ques: Q: What does the kyoto protocol focus on controlling? Read this paragraph and choose the correct option from the provided answers: The Kyoto Protocol is another worldwide agreement on air pollution. It was passed in 1997. The Protocol focuses on controlling greenhouse gas emissions. Its aim is to control global warming. Choices: - carbonate gas emissions - Helium emissions - Ozone emissions - greenhouse gas emissions A:
Ans: greenhouse gas emissions

Ques: Q: What is the process of moving air into and out of the lungs called? Read this paragraph and choose the correct option from the provided answers: Respiration begins with ventilation, the process of moving air into and out of the lungs. Gas exchange in the lungs takes place in across the thin walls of pulmonary arteries in tiny air sacs called alveoli. Oxygenated blood is transported by the circulatory system from lungs to tissues throughout the body. Gas exchange between blood and body cells occurs across the walls of peripheral capillaries. Choices: - naturalization - hydration - insulation - ventilation A:
Ans: ventilation

Ques: Q: Esters are neutral compounds that undergo what process, which is a reaction with water? Read this paragraph and choose the correct option from the provided answers: conditions. Esters are neutral compounds that undergo hydrolysis, a reaction with water. Under acidic conditions, hydrolysis is essentially the reverse of esterification. When carried out under basic conditions, the process is called saponification. Inorganic acids also react with alcohols to form esters. Some of the most important esters in biochemistry are those formed from phosphoric acid. Amines are nitrogen-containing organic molecules derived from ammonia (NH3). A primary (1) amine (RNH2) has one organic group bonded to the nitrogen atom, a secondary (2) amine (R2NH) has two organic groups bonded to the nitrogen atom, and a tertiary (3) amine (R3N) has three organic groups bonded to the nitrogen atom. Amines are basic compounds that react with strong acids to produce ammonium (NH4+) salts. A cyclic compound in which the ring contains one or more noncarbon atoms is called a heterocyclic compound. There are many heterocyclic amines, including many physiologically important ones. Alkaloids are heterocyclic amines found in many plants. Caffeine, nicotine, and cocaine are familiar alkaloids. Organic compounds containing a carbonyl group bonded to a nitrogen atom are amides, and the carbon-to-nitrogen bond is an amide linkage (or a peptide linkage). Most amides are colorless and odorless, and the lighter ones are soluble in water. Because they are polar molecules, amides have comparatively high boiling points and melting points. Amides are synthesized from carboxylic acids and NH3 or amines. Amides are neutral compounds. They resist hydrolysis in water, but acids, bases, and enzymes catalyze the reaction. Choices: - osmosis - cellular respiration - replication - hydrolysis A:
Ans: hydrolysis

Ques: Q: Another major cause of extinction is global warming , which is also known as? Read this paragraph and choose the correct option from the provided answers: Another major cause of extinction is global warming , which is also known as global climate change. During the past century, the Earth's average temperature has risen by almost 1C (about 1.3F). You may not think that is significant, but to organisms that live in the wild and are constantly adapting to their environments, any climate change can be hazardous. Recall that burning fossil fuels releases gasses into the atmosphere that warm the Earth. Our increased use of fossil fuels, such as coal and oil, is changing the Earth's climate. Any long-term change in the climate can destroy the habitat of a species. Even a brief change in climate may be too stressful for an organism to survive. For example, if the seas increase in temperature, even briefly, it may be too warm for certain types of fish to reproduce. Choices: - sudden climate change - rapid climate change - regional climate change - global climate change A:
Ans:
global climate change
