Answer/Explanation:
Red/green colorblindness is a recessive, X-linked condition. That means that the affected gene is on the X chromosome, and that the phenotype will only be present if there is no "healthy" gene, which is dominant to the mutated gene.
For two unaffected people to have an affected son, the mother must be a carrier. Remember, females have two X chromosomes and males have one. So if a female is a carrier of the colorblindness mutation, she will have one copy of the mutation and one normal copy of the gene, and will therefore be unaffected.
The punnet square (attached) shows that all their female children would be unaffected (have the B gene), but 1:2 male children would be colorblind, as their only copy of the gene is mutated (b).

Cellular respiration gives off CO2
Answer: The correct answer is C) Specialized.
Cells that have their own unique structures and functions are called as specialized cells. These cells are present in multicellular organisms. For performing specific function, they have unique adaptations in their structures.
For example- Nerve cells. They receive and transmit nerve impulses from one part to another part of the body. They are connected to other nerve cells or muscle cells in the body. The typical structure of nerve cell consists of body, dendrite, and exon.
As it performs the specific function, therefore, it is an example of specialized cell.
