Answer:
- glomerular filtration rate homeostasis and glomerular hydrostatic pressure homeostasis
Explanation:
Glomerulus receives blood from Afferent arteriole and blood is take away from glomerulus by efferent arteriole. Glomerulus or glomerular capillaries are similar to blood capillaries but are more permeable due to fenestration or pores. The mechanism of urine formation involves three steps of which the first step is glomerular filteration or ultrafilteration. Glomerular flteration depends upon 3 main pressures:
a. glomerular blood hydrostatic pressure (GBHP).
b. capsular hydrostatic pressure
c. blood colloidal osmotic pressure
GBHP is the natural arterial pressure, occurs due to wider diameter of afferent compared to efferent arteriole. GBHP is around 60 mm of Hg. Altering the radii of afferent or efferent arteriole would alter the the glomerular filtration rate by changing the glomerular hydrostatic pressure.
Answer:
Calcium ions
Explanation:
The excitation-contraction coupling process is the process by which the electrical activation of muscles (the depolarization of the action potential) leads to the activation of contraction.
An action potential in the skeletal muscles or muscle excitation leads to Ca release from the sarcoplasmic reticulum via calcium channel protein. Released Ca regulates the contraction of the muscle.
Well, continental drift is the theory that our Earth’s continents slowly float on earth’s mantle. It is actually believed that the earths continents were once a huge landmass, and continental drift caused them to float apart into the landmasses they are today! Plate Tectonics are the movements and changes in the Earth’s land plates, also known mostly as.. continents.
Mineral is made up of usable amounts of metallic elements
Answer: A drawing is just a sketch of what the real cell's look like.
Explanation: Most cells are not going to look the same as you would see in a lab.
