A patient has hypertension. In the long term, this can lead to Chronic Kidney Disease by damaging glomeruli
. Eventually,
glomerular filtration rate falls. Which of the following physiological mechanisms best explains how this
can make hypertension even worse in these patients?
Select one:
a. low GFR leads to a diminished ability to concentrate urine
b. increased Arial natriuretic peptide production leads to sodium and fluid retention
C. low GFR leads to renin-angiotensin-ADH release
d. A chronically high blood pressure leads to too many erythrocytes being produced

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
