Answer:
The correct answers are "The population of birds with large beaks will increase on the island" and "The trait for large beaks will be passed on to future generations through natural selection".
Explanation:
Natural selection functions under the premise of survival of the fittest, where stressful situations such as lack of resources will select the organisms with advantageous traits. In this case, the decrease on seeds affected particularly the numbers of small, soft seeds over large, hard seeds. This stressful situation will select the finches with the advantageous trait of having large beaks, because they are able to feed from large, hard seeds. This trait will be passed on to future generations through natural selection, which eventually will result in the population of birds with large beaks will increase on the island.
Answer:
A. It is a source of genetic variation
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.
