They say how an enzyme perfectly fits into its substrate is alike a "lock and key".
Only one specific enzyme can fit a specific substrate.

Answer: Simple Diffusion Across the Cell (Plasma) Membrane
Explanation:
pretty much the structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
HOPE THIS HELPS!!
Answer:
The correct option is A.
Explanation:
There are two basic types of reproduction, they are asexual and sexual reproduction. Asexual reproduction involves the division of a mature organism into two different organisms through binary fission or other forms of asexual reproduction. In this case the offspring is similar both physically and genetically to the parent organism. There is no genetic diversity in this case and the same disease can easily wipe out the entire population of the organism.
Sexual reproduction on the other hand requires two different organisms. During the reproductive process the genetic materials from the two organisms get mixed up thoroughly, so they end up giving birth to offspring that are quite different from them genetically.
The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.
Stoping- Blocks of rocks falling into magma
Convergent plate boundaries- Places where tectonic plates smash together
Injection- Magma forced into fractures
Magma chamber- Cavity where magma resides
Divergent plate boundary- Area where tectonic plates pull apart
