Hope this helps at least a little :)
Its used to protect genetic diversity and help reintroduce into the wild.
Answer:
D. ABSORPTION
Explanation:
Connective tissues are a type of tissue, made up of ground substance, fibers and cells.
Connecting tissues perform tissue support function using collagen, elastic, reticular fibers.
It is also involved in transport of substances using hemoglobin in blood for transport of nutrients and oxygen, insulating the body, storing of fuel.
I believe option B would be the correct choice because, without a catalyst, the reaction will be either too slow or will not happen at all as it would not acquire a fitting activation energy for the reaction.
If you would like to know why the other options are incorrect, please read on:
Option A is incorrect because since proteins are specific in nature, so other protein cannot be replaced, for some other chemical reaction.
Option C is not correct it is a genetic defect that the protein does not form, and all cells are genetically identical, a reaction cannot take place in any parts of the body.
And finally, option D would be wrong because if a forward reaction does not take place, a backwards reaction will not occur.
I hope this answer has helped, and I apologise if somehow this answer finds itself to be incorrect. Good luck on your quiz or homework. :)
