Answer:
Element
Explanation:
An element is made up of a single type of atom, that is, it’s a substance made up of atoms that have the same number of protons in the nucleus, this number is known as the atomic number of the element. An atom is the smallest particle of an element that retains its properties.Each element is made up of atoms with the same chemical properties such as reactivity, ionization potential. Chemical elements are identified by names given in antiquity, derived from some property of them, from the name of their discoverer, from the place of discovery. In nature there are 92 elements that can be presented (at 1 atm of pressure and 25 ºC) as solid: iron, lead; liquid: bromine, mercury or gas: chlorine, oxygen.

2 or more elements.
All chemical reactions involve the rearrangement of atoms.

Answer:
The correct answer is B make cells produce a functional CFTR protein.
Explanation:
Cystic fibrosis is a disease that is caused due to the mutation in the transmembrane protein known as cystic fibrosis trans membrane conductance regulator or CFTR. Cystic fibrosis trans membrane regulator proteins helps in the formation of thin mucus and due to the mutation in CFTR the mucus becomes thick.The disease cystic fibrosis basically affect the respiratory system.
If gene therapy is used to treat cystic fibrosis then it can replace the mutated CFTR gene with a functional one so that the cell containing CFTR gene can produce functional CFTR protein.
