Question

Whih bype of covalent bond is the strongosr? A single B double C. triple D. quadruple E all covalent bonds are equal in strength Which A cohesion B high heat of evaporation C. high heat capacity D, water is solvent property of water allows it to act as a transport medium E. the frozen form is less dense than the liquid form 10 Which of these statements is NOT true about DNA? 8. Adenine pairs with thymine and guanine pairs with cytosine. C. None of the above D. It contains the sugar ribose. 11. A strand of DNA has the following base sequence (genetic code): ATTGCGAATGGCA The complementary strand of A. ATTGCGAATGGCA B. TAACGCTTTGCGT C. TAACGCTTACCGT DNA would be D. TAAGCCTATCGCT 12. Which of the following is a function of a steroid? sex hormone B. transmission of genetic information C. long term energy storage D. insulation against cold E. protective layer 13. Which carbohydrate is found in the exoskeleton of insects and crabs? A. starch B. chitin C. cellulose D. glycogen E. glycerol 14.DNA and RNA differ in that DNA is single-stranded and contains the sugar deoxyribose and the nitrogen- containing base thymine; RNA is double-stranded and contains sugar ribose and the nitrogen-containing base uracil. DNA is double-stranded and contains the sugar deoxyribose and the nitrogen- containing base thymine; RNA is single-stranded and contains sugar ribose and the a. b. nitrogen-containing base uracil. c. DNA is single-stranded and contains the sugar ribose and the nitrogen-containing base thymine; RNA is single-stranded and contains sugar deoxyribose and the nitrogen-containing base uracil.

Explanation / Answer

8. The strongest covalent bond is Triple covalent bond because it is made by sharing 3 pair of electrons and because of this the distance between the two elements is very small which makes them the strongest.

So option (C) is correct.

9. Water acts as a transport medium because of its solvent properties as it remains liquid over a range of temperatures.

So option (D) is correct.

10. DNA consists of de-oxyribose sugar and not the ribose sugar, therefore this is the incorrect statement.

So option (D) is correct.

11. The complimentary strand to the sequence given ATTGCGAATGGCA is TAACGCTTACCGT.

So correct option is (C).

12. The function of steroid hormone is that it acts as a Sex hormone in our body e.g testes in males produce testosterone and in females ovaries produce estrogen.

So, option (A) is correct.

13.The carbohydrate which is present in the exoskeleton of insects and crabs is CHITIN.

So (B) is correct option.

14. DNA and RNA differ in-

DNA is double stranded, contains deoxy-ribose sugar and the nitrogenous base thymine whicle RNA is single stranded, contains ribose sugar and has nitrogenous base uracil.

So, (B) is correct option.
