Hardness is a physical property of a substance as it describes the  resistance of substance to deformation and can be observed by simple touch or without changing the composition of matter.

While reactivity, toxicity and flammability are chemical properties of substances that change one type of matter into another type.

Cephalopods have complex eyes that arose separately from vertebrate eyes that are also used in vision. what's this illustration
juin [17]

Options:

A. Analogous structures

B. Vestigial structures

C. Homologous structures

D. Missing links

Analogous structures is the illustration in cephalopod. Thus, the correct option is C.

A cephalopod eye, unlike a vertebrate eye, is focused through movement, similar to a camera or telescope lens, rather than altering shape like a human eye lens. The lens, which is totally internal, is nearly spherical, as is the eye.

<h3>What are the characteristics of cephalopod?</h3>

  1. Organs. They have three hearts, two of which transport blood to the gills and the other which pumps blood throughout the body. Their blood is blue because the protein hemocyanin binds oxygen.
  2. Color. Cephalopods have the ability to change the color of their skin at will. They can even use their skin to create elaborate patterns and forms. This is accomplished by the use of chromatophores, which are pigment-filled bags found in the skin. Nerves can change the color of the skin by controlling these chromatophores.
  3. Diet. Cephalopods are all carnivorous animals.

Organs, tissues, or cells in the body that are no longer functional in their ancestral version of the trait are known as vestigial organs.
