In a nutshell what is the relationship between kidneys and nephron

write in Spanish

El riñón está compuesto de nefronas.

Explicación:

La relación entre riñón y nefrona tiene una gran importancia. Nephron es la unidad funcional estructural del riñón. El riñón está formado por millones de nefronas. Nephrons tiene dos partes principales i. mi. una parte funciona como un filtro y ayuda a limpiar la sangre, esta parte se llama glomérulo mientras que la otra parte agrega materiales útiles nuevamente al torrente sanguíneo, esta parte de la nefrona se llama túbulo.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
