Answer:
Oxygen or Glucose
Explanation:
Oxygen and glucose are both reactents in cellular respiration.
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.

Answer:
An elliptical flattened disk. A bulging core with irregular stars around it. A large flattened core at the center.
Explanation:
Answer:
Pyruvate take place after the process of glycolysis.
Explanation:
Pyruvate as intermediate take place in the process of photosynthesis after glycolysis process. One glucose molecule is converted into two molecules of pyruvate. This pyruvate molecule then converted into acetyl CoA, which is a two-carbon molecule. A molecule of coenzyme A is a very important reactant for this reaction, which produces a molecule of carbon dioxide and reduces a NAD+ to NADH.
When the food is scarce, cellular slime molds aggregate into a mass of cells that behaves as a single unit called a slug.
<h3>What is the importance of slugs in slime molds?</h3>
- While feeding, the cellular slime molds live as individual, singled-celled organisms. But when the food is scarce and they have to move to new places in search of food, they aggregate in groups of tens of thousands to form multicellular group called slugs.
- In slug some of the cells contribute to a 2–3 millimeter long stalk, which dries up and dies in the process of formation.
- In the presence of excess food, slime molds are present as independent amoeboid cells.
- It is now observed that in the presence of a food source, some farmer amoebae stop feeding and pocket their food for movement in multicellular migration.
