Pepsin requires an acidic environment, ideally with a pH ranging from 1.5 to 2. Conversely, Trypsin operates best at a pH around 8. Hence, for both enzymes to have optimal activity in a shared environment, it must be at a neutral pH, around 5.
Je ne peux pas vraiment expliquer la réponse à cause de la confusion présente dans votre question, mais je vous encourage à formuler des questions plus claires la prochaine fois.
Response:
2, 1, 4, 3.
Explanation:
The cell membrane potential can be described as the difference in electric gradient between the inside and outside of the cell. Ions play a critical role in creating this voltage difference.
Transmission of nerve impulses occurs through propagation. The cell maintains a resting membrane potential. The opening of sodium channels allows the inward movement of sodium ions, increasing the positivity of the membrane potential and causing depolarization. Subsequently, potassium ions begin to diffuse into the cell while sodium ions exit, resulting in the cell's repolarization.
Thus, the correct sequence of events is 2, 1, 4, 3.
The accurate observation is that the upper cell contains fewer structures while the structures present are comparable.
Geographical Isolation is a mechanism that may have contributed to the emergence of the Hawaiian honeycreeper.
The term Geographical Isolation denotes a group of organisms, be they animals or plants, that are separated and unable to interchange genetic material with others of their species.
Such isolation can occur randomly or by chance.
Below are contributing factors to Geographical Isolation:
1) Physical barriers to movement
2) Separation by distance
3) Isolation resulting from an event
4) Separation by division
