Answer:
Cada nefrona incluye un filtro, llamado glomérulo, y un túbulo. Las nefronas funcionan a través de un proceso de dos pasos: el glomérulo filtra la sangre y el túbulo devuelve las sustancias necesarias a la sangre y elimina los desechos.

Answer:
22
Explanation:
The atomic number indicates the amount of protons, so it would be 22
Answer:
The mass of heavier isotope is 345.6 amu.
Explanation:
Given data:
atomic wight of compound = 342.38 amu
lighter isotope mass = 340.91 amu
abundance of lighter isotope = 68.322%
mass of heavier isotope = ?
Solution:
average atomic mass = ( % age abundance of lighter isotope × its atomic mass) + (% age abundance of heavier isotope × its atomic mass) / 100
percentage of heavier isotope = 100- 68.322 = 31.678
Now we will put the values in formula.
342.38 = (68.322× 340.91) + (31.678 × X) / 100
342.38 = 23291.65302 + (31.678 × X) / 100
342.38 × 100 = 23291.65302 + (31.678 × X)
34238 -23291.65302 = (31.678 × X)
10946.35 / 31.678 = X
345.6 = X
The mass of heavier isotope is 345.6 amu.
Answer:
1.7
Explanation:
Density = M/V
When you divide 4.52 by 2.6, you get 1.738461538, which can be simplified to 1.7.
