This condition occurs when the green pigment, chlorophyll, is reduced or absent in the leaves, causing them to turn yellow. 

Explanation

The two most important factors in the climate of an area are temperature and precipitation.

Explanation

To prepare 250 cm³ (or 250 mL) of a 1 M NaOH solution, you need 10 grams of NaOH.

This is because the molar mass of NaOH is 40 g/mol, and a 1 M solution contains 1 mole of solute per liter of solution.

Therefore, 250 mL (0.25 L) of a 1 M solution would require 0.25 moles of NaOH, which translates to 10 grams (0.25 moles * 40 g/mol).

• The de-oxygenated blood from the heart comes to the lungs through the Pulmonary artery
  ***
• The deoxygenated blood returns from the body to the right atrium and from there enter the right ventricle that pumps it to the lungs through the main pulmonary artery (pulmonary trunk).
• ****
• The pulmonary veins transport oxygenated blood back to the heart from the lungs
