Carrier proteins differ from channel proteins in their role as gatekeepers of the cell in the sense that carrier proteins bind to the substances they transport across the membrane via facilitated diffusion, whereas channel proteins provide a pore for substances to move across the membrane via facilitated diffusion.

Summarily, Carrier proteins BIND TO THE SUBSTANCES while Channel proteins PROVIDE A PORE FOR SUBSTANCES TO MOVE ACROSS.

natima [27]

Answer:

<em>This is an example of natural selection (adaptation).</em>

Explanation:

Natural selection tends to favor those organisms which are better adapted to live in an environment.

As tortoises having flat shell and long neck were better adapted to live in barren area, hence through natural selection those organisms were favored in such an ecosystem.

As tortoises that lived on the vegetative lands were more adapted to live in such an ecosystem, hence through natural ecosystem these organisms were favored and increased in numbers.

3.Commercial development in the U.S. has resulted in an increase in the number of roads, housing developments, shopping centers,
Art [367]

The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.

Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.  

Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.  

With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.
