Why does bacterial growth depend on moisture?
Bacterial growth depends on moisture because water is necessary for most biological processes to occur, including metabolism and cell division. Without sufficient moisture, bacteria are unable to reproduce and thrive. Moisture also helps transport nutrients and waste in and out of bacterial cells.
How does active transport occur?
Active transport requires the use of energy (ATP) to move molecules or ions across a cell membrane against their concentration gradient. This process involves specific proteins, such as pumps or carriers, that bind to the molecules and undergo conformational changes to transport them across the membrane. Active transport is essential for maintaining concentration gradients, ion balance, and regulating nutrient uptake in cells.
Why is the renal portal system absent in humans?
The renal portal system is absent in humans because we lack the renal portal vein, which connects the renal portal circulation from the hindlimbs to the kidneys in some animals. The renal portal system is not needed in humans because our kidneys receive their blood supply directly from the systemic circulation via the renal arteries.
