Answer the following question given this paragraph: Fungi can produce antibiotics , such as penicillin. Antibiotics are important medicines that kill bacteria, and penicillin was the first identified cure against many deadly bacterial species. Antibiotics only treat bacterial diseases; they can not be used to treat viral or fungal diseases. Q: Which type of diseases do antibiotics treat? Choices: - genetic disorders - viral diseases - nervous diseases - bacterial diseases A:
bacterial diseases
Answer the following question given this paragraph: 40.2 | Components of the Blood By the end of this section, you will be able to: List the basic components of the blood Compare red and white blood cells Describe blood plasma and serum Hemoglobin is responsible for distributing oxygen, and to a lesser extent, carbon dioxide, throughout the circulatory systems of humans, vertebrates, and many invertebrates. The blood is more than the proteins, though. Blood is actually a term used to describe the liquid that moves through the vessels and includes plasma (the liquid portion, which contains water, proteins, salts, lipids, and glucose) and the cells (red and white cells) and cell fragments called platelets. Blood plasma is actually the dominant component of blood and contains the water, proteins, electrolytes, lipids, and glucose. The cells are responsible for carrying the gases (red cells) and immune the response (white). The platelets are responsible for blood clotting. Interstitial fluid that surrounds cells is separate from the blood, but in hemolymph, they are combined. In humans, cellular components make up approximately 45 percent of the blood and the liquid plasma 55 percent. Blood is 20 percent of a person's extracellular fluid and eight percent of weight. Q: What is the term used to describe the liquid that moves through the vessels and includes plasma and the cells and sell fragments called platelets? Choices: - water - pus - bacteria - blood A:
blood
Q: Answer the following question given this paragraph: Three main groups of ocean life are plankton, nekton, and benthos. Plankton float in the water. Nekton swim through the water. Benthos live on the ocean floor. Q: Where do benthos live in oceans? Choices: - On the ocean surface - In deep water - In coral reefs - on the ocean floor A:
A: on the ocean floor
Question: Answer the following question given this paragraph: Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases. All four types of friction are described below. You can see a video demonstration of the different types at this URL:. Q: What 3 types of friction occur between solid surfaces? Choices: - static , arching , rolling - static,desending,sliding - static , ascending , rolling - static, sliding, rolling A:
Answer: static, sliding, rolling

Answer the following question given this paragraph: Reactivity is the ability of matter to combine chemically with other substances. Some kinds of matter are extremely reactive; others are extremely unreactive. For example, potassium is very reactive, even with water. When a pea-sized piece of potassium is added to a small amount of water, it reacts explosively. You can observe this reaction in the video at the URL below. ( Caution: Don't try this at home!) In contrast, noble gases such as helium almost never react with any other substances. Q: The ability of matter to combine chemically with other substances is known as? Choices: - turbidity - solubility - permeability - reactivity A:
**Answer**
reactivity
(Q).
Answer the following question given this paragraph: Enzymes are extremely efficient in speeding up reactions. They can catalyze up to several million reactions per second. As a result, the difference in rates of biochemical reactions with and without enzymes may be enormous. A typical biochemical reaction might take hours or even days to occur under normal cellular conditions without an enzyme, but less than a second with an enzyme. Q: Enzymes in cellular reactions work to do what to the reaction? Choices: - increase yield - decrease heat - slow it down - speed it up A:
(A).
speed it up
