Could the loss of 4% of the cerebral cortex cause the behavior changes noted in Phineas Gage?

Yes

Explanation:

The frontal lobe is the part of the brain that controls personality, decision-making and reasoning. It is a part of the cerebral cortex and the largest in composition.

Phineas Gage was involved in an accident in which a metal rod destroyed parts of his brain. This incident however brought about a drastic change in his behavior.

This incident helped to establish the relationship between the frontal lobe and behavioral patterns.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
