Well the more that get cut down, the less oxygen we get, aswell as more carbon in the atmosphere because there is less trees to absorb it.
Answer:
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Explanation:
You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),
which is used frequently in biological experiments.
Based on your answer above, what is the value of x?
Solution:
A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.
250 ml = 0.250 liter
Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose
Recall:
Mass = number of moles * mass of 1 mole
mass of 1 mole of C12H22O11
= 12(12) + 1(22) + 16(11)
= 144 + 22 + 176
= 342 grams
Mass = 0.1375 * 342 = 47.025 grams of sucrose.
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

Answer:
Pulmonary circuit
Explanation:
Pulmonary circuit of blood circulation serves to carry the deoxygenated blood from the right ventricle of the heart to the lungs and then returns the oxygenated blood from the lungs to the left atrium of the heart. The pulmonary trunk carries the deoxygenated blood from the right ventricle to the lungs.
The right pulmonary artery and the left pulmonary artery of the pulmonary trunk carry the blood to the right and left lung respectively. After the gaseous exchange, the pulmonary capillaries unite to form venules and finally the pulmonary veins which in turn carry the oxygenated blood to the left atrium.
