The correct option is (a) having no backbone.

Invertebrates are the category of organisms that lack backbone. They have some soft tissues and because of this their body is soft as compared to that of vertebrates. Example: jellyfish and sponges. Some of the invertebrates have outer covering which is very hard called as exoskeleton. This helps them to protect from outer injuries and harsh conditions. Example: cockroach, spiders, etc.

Among other changes caused by cell aging, there is an increase in pigments and fatty substances called lipids inside the cell.

Aging occurs in the body's cells, tissues, and organs and it therefore affects the functioning of all body systems. Cell aging makes cells sizes to increase and reduces their ability to reproduce. It causes an increase in pigments and fatty substances (lipids) inside the cell. This makes the cells to be inactive or to function abnormally. Aging also causes the accumulation of waste products in tissues.
