Given below are two statements :
Statement I: Insulin was discovered by Banting and Best in 1921.
Statement II: Insulin controls the process of making glycogen from glucose.
In light of the above statements, choose the most appropriate answer from the options given below:
Statement I: Frederick Banting and Charles Best are rightly credited with the discovery of insulin in 1921. They successfully extracted insulin from a dog’s pancreas, marking a breakthrough in diabetes treatment. Their discovery revolutionised medicine by providing an effective way to control blood sugar levels in diabetic patients.
Statement II: Insulin plays a vital role in regulating blood glucose levels in the human body. It enables glucose to enter cells, where it is converted into glycogen through the process of glycogenesis for energy storage. Without sufficient insulin, glucose remains in the bloodstream, leading to elevated blood sugar levels and metabolic disorders.
Which of the following statements are correct?
A. The Earth is $$22 \frac{1}{2}^\circ$$ tilted on its axis.
B. It takes 23 hours, 56 minutes and 4.091 seconds to rotate on its axis.
C. It takes 365 days, 5 hours and 48 minutes to revolve around the sun.
D. The Earth is also known as the Blue Planet.
Choose the correct answer from the options given below:
A. The Earth is $$22.5^{\circ}$$ tilted on its axis. This is NOT CORRECT. The Earth's axis is actually tilted at approximately $$23.5^{\circ}$$, which is responsible for the occurrence of seasons on Earth.
B. It takes 23 hours, 56 minutes and 4.091 seconds to rotate on its axis. This is CORRECT. This period of 23 hours, 56 minutes, and 4.091 seconds is the exact time it takes for the Earth to complete one full rotation on its axis relative to distant stars.
C. It takes 365 days, 5 hours and 48 minutes to revolve around the sun. This is CORRECT. This duration of 365 days, 5 hours, and 48 minutes is the time the Earth takes to complete one revolution around the Sun. This extra time is accounted for by adding an extra day every four years, creating a leap year.
D. The Earth is also known as the Blue Planet. This is CORRECT. The Earth is commonly referred to as the Blue Planet because approximately 71% of its surface is covered by water. From space, the abundance of oceans gives the planet a predominantly blue appearance.
