Q: Answer the following question given this paragraph: times faster than air. For this reason, high-quality helium-filled balloons are usually made of Mylar, a dense, strong, opaque material with a high molecular mass that forms films that have many fewer pores than rubber. Mylar balloons can retain their helium for days. Q: What material used for helium-filled balloons is dense, strong and opaque, with a high molecular mass that forms films that have many fewer pores than rubber? A:

OPTIONS:
- fiberglass
- cellophane
- foil
- mylar

A: mylar

input: OPTIONS:
- molecules
- cells
- chemical reactions
- solutes Now, answer this question: Answer the following question given this paragraph: Solutes change the physical properties of solvents. They lower the freezing point and raise the boiling point of solvents. Q: What change the physical properties of solvents? A:
A:

Answer the following question given this paragraph: Scientists are searching for ways to create controlled nuclear fusion reactions in order to produce safe nuclear power. Fusion involves only harmless, plentiful elements but requires extremely high temperatures. Q: What type of diseases in humans are caused by protozoa? A:

OPTIONS:
- protozoa diseases
- dysentery
- diarrhea
- protist diseases

Answer: protist diseases

Problem: OPTIONS:
- parasitic
- symbiotic
- contention
- competition
Q: Answer the following question given this paragraph: Competition is a relationship between living things that depend on the same resources. The resources may be food, water, or anything else they both need. Competition occurs whenever they both try to get the same resources in the same place and at the same time. The two organisms are likely to come into conflict, and the organism with better adaptations may win out over the other organism. Q: What is a relationship between living things that depend on the same resources? A:
Answer: competition

Problem:OPTIONS:

****
A: hydrogen and helium

Problem:OPTIONS:
- nonvascular tissue
- cartilage tissue
- scar

Answer the following question given this paragraph: Prostate Gland As shown in Figure 27.2, the centrally located prostate gland sits anterior to the rectum at the base of the bladder surrounding the prostatic urethra (the portion of the urethra that runs within the prostate). About the size of a walnut, the prostate is formed of both muscular and glandular tissues. It excretes an alkaline, milky fluid to the passing seminal fluidnow called sementhat is critical to first coagulate and then decoagulate the semen following ejaculation. The temporary thickening of semen helps retain it within the female reproductive tract, providing time for sperm to utilize the fructose provided by seminal vesicle secretions. When the semen regains its fluid state, sperm can then pass farther into the female reproductive tract. The prostate normally doubles in size during puberty. At approximately age 25, it gradually begins to enlarge again. This enlargement does not usually cause problems; however, abnormal growth of the prostate, or benign prostatic hyperplasia (BPH), can cause constriction of the urethra as it passes through the middle of the prostate gland, leading to a number of lower urinary tract symptoms, such as a frequent and intense urge to urinate, a weak stream, and a sensation that the bladder has not emptied completely. By age 60, approximately 40 percent of men have some degree of BPH. By age 80, the number of affected individuals has jumped to as many as 80 percent. Treatments for BPH attempt to relieve the pressure on the urethra so that urine can flow more normally. Mild to moderate symptoms are treated with medication, whereas severe enlargement of the prostate is treated by surgery in which a portion of the prostate tissue is removed. Another common disorder involving the prostate is prostate cancer. According to the Centers for Disease Control and Prevention (CDC), prostate cancer is the second most common cancer in men. However, some forms of prostate cancer grow very slowly and thus may not ever require treatment. Aggressive forms of prostate cancer,... Q: The prostate is formed of both muscular and which other tissues? A:

A:
glandular
