A membrane's permeability has an impact on the diffusion rate. As membrane permeability increases, the diffusion rate rises.
- The dispersion of materials is also impacted by changes in temperature and pressure values.
- The passive diffusion rate of penetrated molecules through the biomembrane can be used to quantify a membrane's permeability.
- It is well acknowledged that the permeability of any particular molecule depends mostly on its size, polarity, charge number, and molar mass.
- The capacity for materials to flow into and out of a membrane is known as permeability. The ease with which a chemical can diffuse across a cell membrane determines its permeability.
- Only chemicals that can dissolve in fat can typically pass through a cell membrane.
- The electrical potential gradient across the cell membrane and the concentration gradient of the permeant ion across the membrane together make up the net electrochemical driving force.

Answer:
1 and 5; 2 and 6; 3 and 4.
1. intestinal phase -->5. stomach empties and decreases secretions
2. gastric phase---> 6. stomach secretes juice and mixes food into chyme.
3. cephalic phase--->4. prepares stomach for arrival of food
Explanation:
- The first phase is the cephalic phase, this starts before food is ingested, and it prepares the stomach for the food that is to come. The gastric secretion starts due to visual and olfactory stimulates.
- The second phase is the gastric phase, the food is already in the stomach, the gastric secretion increases and the contractions of the stomach mix the food with the secretions to form the chyme.
- The intestinal phase is the third phase, the chyme starts to pass to the duodenum, the first part of the small intestine, and the gastric secretions decreases.
Answer:
Increase in sea level on the low lying countries which leads to degradation and salinification thereby making the soil non-arable. Meanwhile on the mountain regions, melting glaciers caused by rain falling on snow leads to mountain floods, avalanches and extreme rockslide and thereby disrupting agricultural produce and wildlife.
