Secretion is the process in urinary system that leads to the elimination of excessive substances like sodium and potassium in the urine.
Secretion is the process of transfer of waste substances from the blood capillaries into the renal tubule. The waste substances can be ions like sodium, potassium, or hydrogen. The segment of the renal tubule that performs secretion is the proximal convoluted tubule.
Urinary system is also called the excretion system where all the waste ions, minerals and water is transferred out from the body in the form of urine. Kidneys are the key organs of the urinary system. They filter out the impurities from the blood and excrete it out through the urethra by a process called micturition.

Rain forest plants all work together to provide food and shelter for rain forest animals, as well as to convert carbon dioxide to oxygen. Ground-level competition for light and food has resulted in some unusual plant evolution.
Answer:
2.23 atoms
Explanation:
In this question, we first need to change the mass of Nitrogen to moles by using the formula;
mole = mass ÷ molar mass
Molar mass of Nitrogen = 14g/mol
Mass = 5.2x10^-23 grams
mole = 5.2x10^-23 ÷ 14
mole = 0.371 × 10^-23
mole = 3.71 × 10^-24 mol
Number of atoms in Nitrogen atom = 3.71 × 10^-24 mol × 6.02 × 10^23 atoms (avagadro constant)
= 22.3342 × 10^(-24+23)
= 22.33 × 10-¹
= 2.233 × 10°
= 2.23 atoms
It's formed from the decomposition of solvable rocks
