Biology
1 answer:
Elodia [21]3 years ago
3 0

Answer:

It is called pen and it is located at the dorsal side

Explanation:

Squid belongs to the class Cephalopoda, subclass Coleoidea which is characterized by internal shell (unlike subclass Nautiloidea in which shell is located externally).

The shell of the squid (the pen) in very reduced and small, formed from chitin and located at the dorsal side. The pen provides attachment for muscles and it gives the squid stiffness.

Most likely, this internal shell evolved from the  external shell, because it is believed the ancestral of the organisms from the Coleoidea was probably nautiloid-like.

During respirations, select all that apply.
Helen [10]

Answer:

The correct answer will be option- B and C.

Explanation:

The cellular respiration is the process of forming energy molecules through oxidation of food. The cellular respiration takes place in four stages: glycolysis, link reaction, Krebs cycle and electron transport chain.

The glycolysis converts the glucose molecules to form two molecules of pyruvate and two ATP molecules but the total number of molecules formed in cellular respiration is between 36-38 ATP molecules. The electron flow takes place in the electron transport chain which helps in the generation of the proton motive force used to produce ATP molecules.

Thus, Option-B and C is the correct answer.
