Where is the squid shell found and what is it called

Biology
1 answer:
Elodia [21]2 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.

I need help with my science
IgorC [24]

Answer:

A theory is the most logical explanation of events that occur in nature. The explanation often results from the use of the scientific method. First, a problem must be stated. Then, after gathering information, a hypothesis, or logical solution, is formed. The solution is then tested in an experiment. The factor that is tested in an experiment is called the variable. This factor is not contained in the control setup. Sometimes principles of chemistry, the study of how substances change and combine, are involved in experiments. At other times, principles of physics are instead.

The metric system is used for all measurements in science. Some basic units in this system are the liter for volume, the kilogram for mass, the degree Celsius for temperature, and the meter for length. Sometimes, the density of a substance, or its mass per unit volume must be measured. If dimensional analysis is needed, a conversion factor must be used.
