Let's make ;
A = ounces solution A
B = ounces solution B
total number of ounces:
A + B = 120
concentration:
0.65A + 0.80B = 0.7(120)
Substitute A for 120 - B in the second equation to combine them.
0.65(120 - B) + 0.80B = 84
78 - 0.65B + 0.80B = 84
0.15B = 84 - 78
0.15B = 6
B = 6/0.15
B = 40 ounces
Then... A = 120 - 40
A = 60 ounces

I just learned this.
Asexual reproduction takes/or inherits one parent's genes, because it only involves one organism.
Sexual reproduction requires both a male and female.
<h3><u>Answer;</u></h3>
exceeds evaporation over land
Precipitation<u> exceeds evaporation over land </u>
<h3><u>Explanation;</u></h3>
- <em><u>In order to maintain earths water balance, evaporation exceeds precipitation over oceans but precipitation exceeds evaporation over land.</u></em>
- Water evaporates into the atmosphere from the ocean and to a much lesser extent from the continents. Winds transport this moisture-laden air, often great distances, until conditions cause the moisture to condense into clouds and to precipitate and fall.
- Most precipitation originates by evaporation from the oceans. Over time, water evaporated from the oceans is replenished by inflow of freshwater from rivers and streams.
