<span>One test might be the acid content of the water. Water that does not have a neutral pH might be less conducive to life. Another water quality test might be oxygen levels in the water. Inadequate oxygen levels may also reduce the amount of aquatic life. The presence of pollutants might be a third test. Chemicals that poison the water would negatively impact the number and variety of organisms present.</span>
Answer:
70-80% of women experience postpartum depression
Explanation:
Answer:
Cell membranes are essentially lipid-based so they're hydrophobic. Therefore, most hydrophobic molecules can pass through the cell membrane

Answer:
B. The conditions in their muscles have become anaerobic.
Explanation:
In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.
What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.
Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".
choices are:
Mike is right because the atomic mass of lithium is 6. There are 3 protons and 3 electrons in the atom. 3+3=6
Joan is right because the atomic number of carbon is 6. There are 3 protons and 3 electrons in the atom. The atomic number shows the number of protons plus the number of electrons. 3+3=6
Joan is correct because carbon is a neutral atom. There are the same number of protons and electrons in the atom pictured.
Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
Li has atomic no. 3 and mass 7. so the correct ans is Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
