The expected frequencies are f(A1) = 0.9700, f(A2) = 0.0300 according to the Hardy-Weinberg model. For biologists studying a large flatworm population in the lab, which Hardy-Weinberg condition is most difficult to meet there is no mutation. It is called a genetic disorder in homozygous recessives that causes death during the teenage years.

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.

Aminosyn is an amino acid often times used in tpn orders to provide protein for cellular repair and growth. a physician writes a
love history [14]
I think theres a few methods to do it, but this is probably the most efficient.

Physician has prescribed 2.5% of 500ml
Actual amount of Aminosyn in this prescription is
500*0.025= 12.5ml of Aminosin

Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.

To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%

Therefore 1% = 12.5/8.5= 1.470588

Therefore the amount of 8.5% solution you need to pour is 100* 1.470588= 147.1ml

Then make up the rest(352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.
