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.
Answer:
Excretion is the removal of material from one living thing, for example. Humans excrete tears, sweat, carbon dioxide etc.
Secretion is the movement of material from one point to another, for example. Humans secrete enzymes, hormones, saliva etc.
Basically in summary excretion is the removal of physical material and secretion is the movement of biological materials from one point to another.
I hope this was clear enough lol
