The gas leaves the atmosphere as plants use it to make sugar.
Explain
since in the carbon cycle CO2 goes into plants, creating sugar molecules that the animals then eat and as a result breathe out the CO2 back into the atmosphere
Just divide!
60 seconds = 1 min
60 mins = 1 hour
1987 seconds divided by 60 seconds = 33.11 minutes
Your answer would be 33 minutes and 11 seconds
Answer: biological adaptation
Explanation:
lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.
I hope this helps :).
Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors<span>. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is </span>brittle<span> - a characteristic of some nonmetals).</span>
Answer:
Mass of KBr present = 2.23 g
Explanation:
Number of moles of KBr present in 75.0 ml of 0.250 M solution of KBr is first determined
From the formula: molarity = number of moles/ volume (L);
Number of moles = molarity * volume (L)
Volume of solution in Litres = 75/1000 = 0.075
Number of mole = 0.250 * 0075 = 0.01875 moles
Mass = number of moles * molar mass
Molar mass of KBr = 119 g/mol
Mass = 0.01875 moles * 119 g/mol = 2.23 g
