Answer: temperature and
Explanation: temperature and
and humidity the most essential factor affecting the speed of sound in gas.. in gas, sound speed changes with change in temperature. For stable temperature, the speed of sound is independent of pressure. For every increase in temperature, there is a corresponding increase in thermal energy as molecules do resonate faster. Humidity has little effect on the speed of sound. The speed of sound also depends on d relationship between molecules in gas
Answer: (A) Narrowing of the artery causes the velocity to increase and the hydrostatic pressure to decrease.
Explanation:
Atherosclerosis is a disease which allows plaque to build up inside the arteries of a person. Arteries are responsible to carry oxygen-rich blood to heart and other areas of the body.
Plaque consists of cholesterol, calcium, fat, and other substances which are present in the blood. Through time, the plaque hardens the arteries and narrows them. That restricts the oxygen-rich blood flow to your organs and to other parts of your body.
Atherosclerosis can cause serious problems, including stroke and heart attack.
Hence the correct option is (A).
Answer:
Can of soup and pop Tarts.
Explanation:
Can of soup will provide 1 mole of sodium whereas pop Tart provides potassium in the least mass because the concentration of sodium and potassium in can of soup is higher than other food items. The can of soup has 300 mg of sodium and pop Tart has 0.5 g of potassium while on the other hand, honey nut, frosted flakes, Oreos and pop Tarts has 0.14 g, 0.12 g, 0.3 g, and 0.35 g of potassium respectively and can of soup, honey nut, frosted flakes and Oreos has 190 mg, 150 mg, 80 mg, and 180 mg of potassium respectively which is lower than pop Tart so we can say that less amount of pop tart provides more potassium. 9579 of soup and 7505 of pop Tart are the masses required for I mole sodium and potassium.
Answer: B. Nuclear transfer!
Explanation:
Nuclear transfer is the process that DNA goes through to get cloned/copied. The cells that make new forms of DNA create a perfect replica.
