Answer:
An increase in membrane thickness
Explanation:
Gaseous exchange occurs in relation to Fick's Law which states:
'the rate of diffusion is proportional to both the surface area and concentration difference and is inversely proportional to the thickness of the membrane
Therefore, based on this law, an increase in the thickness of the membrane will result in a decreased diffusion rate which will in turn slow down the process of gaseous exchange
Answer:
Explanation:
While passing through renal tubules, water and a lot of other substances are reabsorbed making filtrate concentrated. This also gradually results in an increase in the concentration of urea as it is not reabsorbed like water or glucose. Some substances like K+, H+ are also secreted (not urine).
Answer:
Passice immunity
Explanation:
Breast milk, produced by female mammals (including humans), besides being rich in fat and protein is full of IgA. IgA is the immunoglobulin (immune system signal proteins) that is present in body secretions, such as milk.
The baby that is fed from the mother's breast ingests these defense proteins that allow it to tolerate different pathogens and toxins.
It is considered passive immunity, as it does not generate memory and depends on a continuous dose to maintain defense levels.
