Answer:
The correct answer is - duplication.
Explanation:
CMT or Charcot-Marie- Tooth is an inherited disease of muscular wasting that affects the arms and legs of an individual due to nerve damage mostly peripheral nerves that leads to smaller and weak muscles. This inherited disease is found to be due to the mutation that takes place on chromosome 17.
The mutation is duplication type due to fact that the short arm of chromosome number 17 takes place and copy the new copy of p-arm or short arm.
Thus, the correct answer is - duplication.
Answer:
b) Operons for coordinated gene expression
Explanation:
Operon refers to a unit of genetic function and is mainly found in bacteria and phages. An operon consists of a promoter, an operator, and a coordinately regulated cluster of structural genes. The genes of an operon code for proteins or enzymes that mostly function in a common pathway. It allows a single promoter and operator or any other regulatory sequence to regulate the expression of functionally related genes.
For instance, lac operon consists of three structural genes that code for the enzymes involved in the catabolism of lactose sugar. The operon is expressed only when lactose is available in the medium. This pattern of gene regulation is not found in eukaryotes.

Answer:
Habitat ( plural : habitats ) are terrestrial or aquatic territories that differ in geographical , abiotic and biotic characteristics , whether they are fully natural or approximately-natural. All living things need a place where they can grow, feed, live and multiply. This place is called habitat. Habitats can be as big as a lawn or as small as a pond. There may be several habitats in the same area of land or sea. Some of the habitats may be mountains, forests or shores
