The answer is b because it will still fall as something else
The function of a cell membrane is to protect the structures within the cell, give shape to the cell and support its structure.
The four mechanisms are as follows:
1) Orographic lifting: Air is forced to rise over a mountainous barrier
<span>
2) Frontal wedging: Warmer, less dense air is forced over cooler, denser air along a front
</span>
<span>3) Convergence: Pileup of horizontal air flow resulting in an upward flow
</span>
<span>4) Localized convective lifting: Unequal surface heating causes localized pockets of air to rise because of their buoyancy. </span><span />
1. Species vary over time
2. The fossil and the living species will have some similarities and some differences
The answer is differentially permeable or semi-permeable, both are the same meaning. It is usually about cell membrane, and for example osmosis has to occur under this kind of membrane
