Question

question 11: a negatively charged subatomic particle that moves around the nucleus is a(n): orbital. proton. neutron. electron. question 12: the approximate ph of gastric fluid is: 10. 8. 4. 2. approximately what percentage of the body weight of an adult female is water? 40% 50% 60% 70%

Explanation:

• For the question about the percentage of water in an adult - female's body weight, on average, water constitutes about 50% of an adult female's body weight. Males have a higher percentage due to more muscle mass which contains more water.
• For the question about the negatively - charged subatomic particle that moves around the nucleus, electrons are negatively charged and orbit the nucleus. Protons are positively charged and are in the nucleus, neutrons are neutral and also in the nucleus, and an orbital is the region where an electron is likely to be found, not a particle.
• For the question about the approximate pH of gastric fluid, gastric fluid is highly acidic, with a pH around 2. This acidity helps in digestion by breaking down food and killing bacteria.

Answer:

Question 10: B. 50%
Question 11: D. electron
Question 12: D. 2
