What is the most important abiotic factor that<br> limits distribution of the tundra biome?
Ludmilka [50]

Answer:

Temperature is the most harsh abiotic factor that limits distribution of the tundra biome.

Explanation:

The tundra biome can be described as a biome that is one of the most abundant biome of the earth but allows little growth of trees due to its very cold temperatures. Often, in a tundra biome, no trees would be seen. The ground soil of this biome remains frozen most of the year and is termed as permafrost. The tundra biome shows very little biodiversity due to the extreme cold conditions. Very few animals and plants are adapted to live in these conditions.

Describe and explain enzyme​
gizmo_the_mogwai [7]
Nzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site. There are two theories explaining the enzyme-substrate interaction.
