Answer:
The answer is 1/16.
Explanation:
The probability of getting a heads first is 1/2. The probability of getting 2 heads in a row is 1/2 of that, or 1/4. The probability of getting 3 heads in a row is 1/2 of that, or 1/8. The probability of getting 4 heads in a row is 1/2 of that, or 1/16.

The correct answer is option A, that is, a solution with a pH of 1.
pH refers to the unit of measure utilized to articulate the extent of acidity of a substance. The pH scale varies from 0 to 14. A pH of 0 means a very high acid activity, the hydrochloric acid, and nitric acid are very strong with pH values of 0, while the stomach acid exhibits a pH of 1.
Technically, the scale of pH, in reality, depicts the amount of positively charged H+ ions and negatively charged OH- ions in a solution. The pH scale is a logarithmic one, that is, each unit of pH exhibits 10 times as more ions of hydrogens in comparison to the unit above it.
Therefore, in a solution of pH 1, there are 10^9 times more hydrogen ions in comparison to the solution at pH 10.
Answer:
Option A
Option D
Option F
Explanation:
During the process of continuous starvation for a long period of time, the primary source of energy in body is hepatic gluconeogenesis which is responsible for producing endogenous glucose. Also lipolysis takes place in the adipose tissue to release fatty acid which is then converted into ketone bodies through though mitochondrial β oxidation and ketogenesis. The liver communicates with extrahepatic tissues, including adipose tissue and skeletal muscle and deliver glucose and ketone bodies to muscle and other extrahepatic tissues as fuels.
Hence, option A, D and F are true.
