That would be summer to winter those changes would occur
Salt because adding salt lowers the freezing tempurature of ice (basically it has to be colder to stay frozen)
Answer:Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism. Organisms ingest organic molecules like the carbohydrate glucose to obtain the energy needed for cellular functions. The energy in glucose can be extracted in a series of chemical reactions known as cellular respiration. Most energy is produced during cellular respiration in the mitochondria, a process that involves breakdown of simple sugars to produce energy in the form of ATP, which is the usable form by the cell.
Explanation:
<span>The organs that participate in vitamin D synthesis and activation are kidneys and liver.
</span>Vitamin D<span> is carried in the bloodstream to the </span>liver, where it is converted into the prohormone calcifediol.<span>Calcifediol is further hydroxylated by the kidneys to form </span>calcitriol and c<span>alcitriol circulates as a hormone in the blood, and regulates the concentration of </span>calcium<span> and </span>phosphate.
Well the <span>blood returns from the cardiac tissues to the right atrium because
the blood goes through the tricuspid</span> valve and into the right ventricle then the right ventricle makes the blood go to the lungs and thats where the oxygen is at then the blood goes through organs and tissues then gets to the heart through the veins and a vein named the vena cave has the blood return to the right atrium.
