Answer:
Option B, Tinea capitis
Explanation:
Superficial fungal infection of skin of head or scalp is known as Tinea capitis.
These fungal infection attack the hair shafts and follicles and is a superficial form of mycosis or dermatophytosis.
Tinea cruris is the superficial infection of genitals, buttocks and inner thighs regions. Hence, option A is incorrect.
Tinea pedis is the superficial infection of foot and regions between the phalanges. Hence, option C is incorrect.
Tinea corporis is the superficial infection of arms, legs or skin. Hence, option D is incorrect.
Thus, option B is correct.
Answer:
Some statements of the question are missing but it can be understand as the Hydrogen bonds are Easy to break, Less amount of heat required, Less amount of enzyme needed and Can be broken by mild concentration of enzyme.
Explanation:
Weak bonds like hydrogen bonds are found to beneficial in some situations. During the duplication of chromosomes which occurs in S phase of cell cycle the DNA replicated. This replication is facilitated by separation of the two strands of DNA and formation of complimentary strand on the two primary strands. The enzymes involved in the process of separation of strands are DNA helicase and Topoisomerase mainly. As the bonds between the strands are weak hydrogen bonds, the enzymes function effectively without requiring extra heat or more saturation. It will found to be difficult if those bonds will be covalent bonds because they are much stronger than hydrogen bonds and are not easily broken by these enzymes. Extra processes will be required to break those strong bonds.
