Answer:
Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.
Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.
Explanation:
Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.
Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.

Explanation:
Though the effect of ships disappearing over the horizon <em>is </em>due to its spherical shape, it could also be used evidence for objects falling off the "edge" of a flat, planar-shaped earth.
Answer:
The tree absorbs light energy from sunlight, converting the light energy into chemical potential energy stored in chemical bonds. The tree uses this energy to build leaves and branches and fruit. When the apple hits the ground, kinetic energy is transformed into heat energy.

Explanation:
Organism is a binomial name meaning it is made up of two words.
The Body Structures of some species support Darwin's Theories because of fossil records, similarities in DNA and protein sequences between organisms, homologous <span>and vestigial body structures, and similarities in early development. Also, they have similar limbs.
