<span>"Carrier proteins bind to the substances they transport across the membrane via facilitated diffusion, whereas channel proteins provide a pore for substances to move across the membrane via facilitated diffusion."
This is the most correct option.
The main difference, when comparing these two gates of transportation across a membrane through the same process (via facilitated diffusion or any other), is that carrier proteins bind to the substances they transport and only communicate with one environment of the cell (whether intracellular or extracellular) at the time, while channel proteins let substances move across the membrane without any binding being opened to both cell environments.</span>
Answer:
fluvial wetlands
Explanation:
The earliest megafossils of land plants were thalloid organisms, which dwelt in fluvial wetlands and are found to have covered most of an early Silurian flood plain. They could only survive when the land was waterlogged.
<span>A preload (stretching) is greater in cardiac muscle fibers before contraction increases its contraction force. This preload is compared to the stretching of an elastic band because the more stretched that band, the more strongly it will return to its resting length. Within certain limits, the more the heart fills with blood during diastole, the greater the contraction force it will exert during diastole. The preload is proportional to the end-diastolic volume. Normally, the higher the end-diastolic volume, the greater the force that the heart will develop in the next contraction.</span>
