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>
- 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.
- 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.
- 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.

the person above me is also correct
Answer:
b. Restriction enzymes cutting DNA
Explanation:
Restriction enzymes are the enzymes that cut the DNA molecules. Their specific feature is that they digest the specific DNA sequences only. These specific DNA sequences are called restriction sites. When some restriction enzymes digest the DNA, DNA fragments with single-stranded ends are produced. These single-stranded overhangs are called sticky ends. They are called so since the DNA fragments produced by digesting DNA with one restriction enzyme have complementary overhangs that spontaneously base pair.
Answer:
"Up" or "against" a concentration gradient means from low concentration to high concentration. Moving in this direction requires some sort of energy input, such as active transport using ATP, or an electrical gradient, or something else.
