Answer: unlike modern-day evolutionary geneticists, Darwin did not have the knowledge of modern-day genetics or the ability to sequence the genome. So, Darwin couldn’t have determined that the trait of flightless wings was likely caused by a genetic mutation.
Explanation:
Answer:
C.
because a force is what causes an object to move
Osmosis is the movement of <em>water </em>from a region of higher water concentration to a region of lower water concentration across a selectively permeable membrane. Simply put, water passes across membranes into areas where more 'stuff' is dissolved.
In this system, The slice shriveled in salt solution. That means water left the potato's cells. Then the slice regained its shape when placed in pure water. That means water moved back into the cell.
A) <em>incorrect</em>. Salt does not move across the membrane
B) <em>incorrect</em>. If water moved into the slice, it would have swelled, not shriveled
C) correct. Water moved out of the cell into the more concentrated salt solution
D)<em>incorrect</em>. Placing the slice in pure water does not balance the concentration of salt between the cells and the water.<em />
I don't know, maybe because of the way we see animals. Not as our equal parts
