Potassium-40 has a half life of 1.251×billion<span> years</span><span>. To determine the percentage potassium-40 remaining after 3.9 billion years, divide
3.9 by 1.251, = 3.12.
This is the number of times the original amount of potassium-40 reduces by 50%. The remaining percentage is therefore 100%/(3.12 * 2) = 16.03%.</span>
Answer:
The two strands of the parent DNA are separated, and two daughter DNA strands are formed.
Explanation:
DNA replication is a complex process which replicates or produces new DNA molecule from the parent DNA molecule mediated by enzymes and ATP.
The mechanism of DNA replication is known as the semi-conservative mode in which one new strand of DNA is synthesized complementary to the one strand of DNA. To form a new DNA molecule both the strand of the DNA gets separated and then a new daughter strand is formed complementary to each parent strand.
Thus, the selected option is correct.

The nasal cavity and its mucous have two primary purposes in the process of breathing: Role as a Passage for Inhaled Air: During inhalation, air enters through the nostrils and passes via the nasal cavity into the pharynx and larynx, the next sections in the respiratory tract, to eventually reach the lungs.
Explanation:
Most fat-soluble nutrients are absorbed in the Lymphatic system.
<h3>What is Lymphatic System?</h3>
A network of tissues, veins, and organs known as the lymphatic system collaborates to transport lymph, a colorless, watery fluid, back into your circulatory system (your bloodstream).
Your body's arteries, smaller arteriole blood vessels, and capillaries each day carry about 20 liters of plasma. About 17 liters are then returned to the circulation through veins after providing nourishment to the body's cells and tissues and collecting their waste products. The remaining three liters permeate your body's tissues via capillaries. The lymphatic system gathers this extra fluid, which is now known as lymph, from your body's tissues and transports it to various locations before returning it to your bloodstream.
