Correct Answer: B. Amino acids would not bind to tRNA molecules.

Explanation

tRNA synthetase plays a vital role in translation, but not transcription. tRNA synthetase is the enzyme that binds specific amino acids to corresponding tRNA molecules, and then the tRNA molecules transport the amino acids to the ribosome to create a polypeptide. tRNA molecules are not consumed in this process, and tRNA reserves will not be depleted if tRNA synthetase were non-functional.

Correct Answer: D. aluminium

Explanation

Let's analyze each element:

• A. Lithium (Li): Atomic number 3. Electron configuration: [He] 2s¹. The last electron enters the s orbital, making it an s-block element (Group 1).

• B. Magnesium (Mg): Atomic number 12. Electron configuration: [Ne] 3s². The last electron enters the s orbital, making it an s-block element (Group 2).

• C. Potassium (K): Atomic number 19. Electron configuration: [Ar] 4s¹. The last electron enters the s orbital, making it an s-block element (Group 1).

• E. Aluminium (Al): Atomic number 13. Electron configuration: [Ne] 3s² 3p¹. The last electron enters the p orbital, making it a p-block element (Group 13).

Therefore, Aluminium is the s-block element.

The correct answer is D. aluminium.

Correct Answer: D. 5.82 cm

Explanation

\(r_1\) = 4.5cm , \( P_1\) =is the total pressure on the bubble at a depth of 12m from the surface.

\(P_1\) = 12 + 10.34 =22.34m

\(V_1\) = \(\frac{4}{3}\)π× \(r^3_1\)

= \(\frac{4}{3}× π×{4.5^3cm^3}\)

\(P_2\) = 10.34m

\(V_2\) = \(\frac{4}{3} {π}{r^3_2}\)

from boyles law:

\(P_1V_1\) = \(P_2V_2\)

⇒ 22.34× \(\frac{4}{3}× π×{4.5^3}\) = 10.34 × \(\frac{4}{3}×π×{r^3_2}\)

⇒ 22.34 × \(4.5^3\) = 10.34 × \(r^3_2\)

⇒ \(r^3_2\)= \(\^3√196.88\)

⇒ \(r^3_2\) = 5.82cm

Correct Answer: D. Discount rate

Explanation

Discount rate is the minimum interest rate set by the central bank of a country. It is used in controlling inflation. We all know inflation is an economic situation where the value of money falls and causes a rise in the general price level. Inflation occurs when there is excess money in circulation. This means that, much money will be used to purchase few goods. The central bank uses discount rates to control inflation by taking out the excess money in circulation. They do this by increasing interest rates to encourage people to save or invest and discourage borrowings. By saving and investment, the excess money in the economy is taken out. For instance, if interest rates are set at 20%, people would prefer to save or invest their monies so as to get a high return on investment rather than borrowing from the banks and pay high interest rates.

Correct Answer: B. maintain personal relationship with customers

Correct Answer: D) go with Aaron who would speak for him

Explanation

Moses was a man chosen by God to deliver the Israelites from slavery in Egypt. However, when God called him, Moses resisted because he felt he could not speak. In response, God told Moses to go with his brother Aaron, who would speak for him. This is the correct answer to the question.

Option A, performing some signs with his rod, is not the correct answer because while God did give Moses miraculous signs to perform, he still needed someone to speak for him. Option B, waiting for a sign from God, is also not the correct answer because God had already spoken to Moses and given him instructions. Option C, going with Joshua who would speak for him, is not the correct answer because while Joshua was a great leader, he was not the one chosen by God to speak for Moses.

It is important to note that Moses' reluctance to speak was due to his own insecurities and doubts, but with Aaron's help, he was able to fulfill God's plan for him. This story also teaches us about the importance of trusting in God's plan and being open to the help of others.
