Answer:
d) a polypeptide missing an amino acid.
Explanation:
Deletion is a type of mutation when one or more codons from the reading frame are removed. This results in the production of a relatively shorter mRNA that lacks one or more codons otherwise present in the non-mutated mRNA. When there is a deletion of a single codon in the gene for cystic fibrosis, the resultant shorter mRNA codes for a polypeptide chain that does not carry one amino acid. For example, deletion of one codon results in deletion of a Phe residue present at position 508 in CFTR. The mutated transmembrane protein CFTR folds in an improper way.

Answer:
Parasitism
Explanation:
Parasitism is the form of mutual relationship between two organisms which occurs in such a way that one organism always get benefit and the other always gets harm. The one getting harm may or may not be killed due to it.
There are many common parasitic relationships we see in eco system.For example, when a tick sucks blood out of a dog. it is causing harm to dog by decreasing the content of blood however getting benefit for itself since blood is its food and the nutrients present in blood are source of energy for tick.
Similarly, Malaria is caused in human by a parasite called plasmodium. It enters into the blood and causes a disease called Malaria which can even lead to the death of affected individual,the parasite itself stays healthy and gets benefit.
Hope it help!
The relationship between cats and mice could be best described as 'Predator-Prey'.
<h3>{Differences in Physical Characteristics}</h3>
Vertebrates have a skeletal structure with a spinal column or backbone.Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.
Explanation:
<h3>{Invertebrates}</h3>
•Invertebrates do not possess a backbone not an internal skeleton.
•Invertebrates have an exoskeleton.
•Body size varies but most are generally smaller than vertebrates. However, some invertebrates grow to gigantic proportions – such as the colossal squid (46 feet in length).
<h3>{Vertebrates}</h3>
•Vertebrates possess a backbone and an internal skeleton.
•Vertebrates do not possess an exoskeleton.
•Generally, vertebrates are comparatively larger than invertebrates
