Clostridium botulinum is an anaerobic, spore-forming, bacterium organism that releases a toxin that causes muscle relaxation. The toxin that is released is a neurotoxic protein: Botulinum toxin (BTX) and <span>is produced only in an anaerobic environment. </span>This toxin is used as a a medicine to treat overactive muscle movement.
Answer:
The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.
Explanation:
The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.
<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated
.
The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.

Mesonychids are the hypothesized link between whales and the hooked mammals.
<u>Explanation:</u>
The scientific name of the Mesonychids are the mesonychia. Taxonmically hippos and pigs are the sister taxon to whales. The mesonychids are the evaluation of whales was determined within an extinct group of carnivores hooved animals. They found in the Asia and Europe.
Mesonychids live in both the land and sea world. The generation transformation influence the link between whales and the hooked mammals. its is also closely related to the cetaceans, which includes dolphins and whales.
