They are reactants because they are present before the reaction.
Answer: Convergent Boundary
Explanation:
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. ... Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere.
The variety of organisms that occupy a given region including microscopic protists to large mammals. The region can be a political unit such as a country a geographic feature such as a mountain range or the entire world. The first level of bio diversity is genetic diversity. Next is taxonomic diversity. Also ecological diversity.
Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
