The Sun shines because it is able to convert energy from gravity into light. ... This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion.
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.
Ok so choose 2 ecosystems which is not that hard aquatic and terrestrial research your information on the sight i can not do the work for you, don't forget to check your spelling and punctuation
