Answer;
B. arteriosclerosis
High levels of cholesterol can first lead directly to arteriosclerosis.
Explanation;
Atherosclerosis refers to the buildup of fats, cholesterol and other substances in and on your artery walls (plaque), which can restrict blood flow. The plaque can burst, triggering a blood clot.
Arteriosclerosis can occur when arteries grow thick and stiff and restrict blood flow to organs and tissues in the body. This gradual process, also known as hardening of the arteries, weakens arteries and can develop in various organs, most commonly the heart.
Answer:
ka = 2x10⁻⁹
Explanation:
Using the pH we can <u>calculate the molar concentration of H⁺</u>, [H⁺]
- = [H⁺] = 2.24 x 10⁻⁵ M
Then we use the expression of Ka for the equilibrium of a weak monoprotic acid:
HA ↔ H⁺ + A⁻
Where:
ka =
ka = = 2x10⁻⁹
Advantages of parallel combination over series combination are:
1) In parallel combination each appliance gets the full voltage.
2) If one appliance is switched on/of others are not affected.
3) The parallel circuit divide the current through the appliances. Each appliance gets proper current depending on its resistance.
4) In a parallel combination it is very easy to connect or disconnect a new appliance without affecting the working of other appliances.
