Active transport uses cellular energy to move molecules based on the concentration level and Passive transport doesn't require energy to move molecules within their cells.

EXPLANATION:

Active transport uses cellular energy for this movement. It uses energy stored in ATP to begin the transport. This means that the molecules transfer from an area where it is less in number to an area with a high concentration of molecules.

But Passive transport specifies the movement of molecules across cell membranes which doesn't require energy as it depends on the cell membrane's penetrability. Molecules just have to circulate in or out of the cell.

During a study session about evolution, one of your fellow students remarks, "The giraffe stretched its neck while reaching for

kondor19780726 [428]

Answer:

For part 1

The statement to correcting the student's misconception is that 'ACQUIRED TRAITS CANNOT BE INHERITED'

For part 2

The statement is True - Traits acquired during lifetime ARE NOT passed on through genes.

Explanation:

For part 1 and 2

The appearance of an organism depends on TWO FACTORS:

- inherited traits contained in genes, and

- environment

Therefore, the stretched neck on the giraffe is due to its adapting to the environment so is an ACQUIRED TRAIT, and would NOT alter the gene for "normal neck" present in its chromosome.

So, no matter what evolution recognizes that, 'ACQUIRED TRAITS CANNOT BE INHERITED' in the giraffe offsprings but traits contained only in the genes.
