What is phrenology, and what role did it play in the development of ideas about brain localization?
Eva8 [605]

Answer:

Hello YOU!

Explanation:

Phrenology was a science of character divination, faculty psychology, theory of brain and what the 19th-century phrenologists called "the only true science of mind."Phrenology came from the theories of the idiosyncratic Viennese physician Franz Joseph Gall (1758-1828).

Gall believed that the bumps and uneven geography of the human skull were caused by pressure exerted from the brainunderneath. He divided the brain into sections that corresponded to certain behaviors and traits that he called fundamental faculties. This is referred to as localization of function.

Phrenology is considered pseudoscience today, but it was actually a vast improvement over that era's prevailing views of personality. ... But phrenology may be undergoing a redemption of sorts. Not the skull part—that's still considered bunk.

Phrenology was particularly popular in the U.S. because it fit so well with the idea of the American dream–the notion that we can accomplish our goals despite a humble heritage. Spurzheim believed that the brain was like a muscle that could be exercised.

Which macromolecule forms a double layer as the primary structure of cell membranes?
OlgaM077 [116]
Answer;
Phospholipid.

Phospholipid forms a double layer as the primary structure of cell membranes.

Explanation; 
Cell membranes contains of lipids (phospholipids and cholesterol), proteins and carbohydrates groups that are attached to some of the lipids and proteins. 
Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.

Why is HCl poured on the DNase test agar plates that you inoculated last period?
tia_tia [17]

Answer:

A. To cause intact DNA to precipitate, so the activity of DNase can be determined.

Explanation:

The presence of DNase is special feature for some species of bacteria and can be used for identifying them. During DNase test, diluted hydrochloric acid (HCl) can be poured onto the agar plates so that there will be a clear zone close to the bacteria colonies. Each nucleotides are soluble in diluted HCl. But DNA is not soluble in the diluted HCl, thereby making the DNA to precipitate in the rest of the plate.
