Answer

The ATP molecule is necessary in this type of transport due to the particles are moving against the concentration gradient.

Explanation:

ATP is needed for many functions that require energy, and one of them is active transport across the cell membrane.

Unlike passive transport, where particles move along the concentration gradient, active transport -which uses the energy of ATP- is characterized by mobilizing particles against the concentration gradient.

The cell membrane is semi-permeable, so some substances cannot pass freely, requiring transporters to be able to pass through it.

Other options are not true for:

<em>     A. A charged particle can move through a channel specific to it. </em>

<em>     C. There is no particle entrapment in the plasma membrane. </em>

<em>     D. Particles do not move in favor of a concentration gradient.</em>

Scientists have observed that pythons have vestigial leg bones. They have also observed that snakes in general have more DNA seq
hichkok12 [17]
The answer is <span>They both suggest that snakes evolved from an ancestor with legs.

The second choice is not correct since we have no information about pythons and other snakes. We only have the relationship between geckos, snakes and legless eels. So, it is said that </span><span>snakes in general have more DNA sequences in common with four-legged geckos than they do with legless eels. This means that snakes are closer to geckos than the legless eels. We cannot conclude from this information which evolved from which, but we can say that </span><span>snakes evolved from an ancestor with legs.
In different case, if the snakes had more DNA sequence in common with legless eels, we would conclude that the snakes evolved from an ancestor without legs.</span>
