9th Grade Biology
Thank you SO much

9th Grade Biology
Assume that the fish have an average mass of 280g. The average caloric value is 8kcal/g. The heron is able to digest 60% of the fishes’ mass. How many will it need to eat to sustain its caloric intake of 3,000kcal/day?

Pre-Algebra 7th grade.
(94 - 6) / (66/6) = 88 / 11 = 8 88 / 11 = 8 8 = 8

you use the density formula density=mass/volume and solve

what happens at the molecular level if the temperature of a CO2/H2O solution increases? I know that has the temp. goes up the solubility decreases, but i don't really know what that means.
