The parietoacanthial projection (Waters method) of the facial bones is often modified so that there is less angulation of the fa

cial bones. For this modification, the orbitomeatal line is adjusted to _____ degrees.
a) 30 degrees
b) 37 degrees
c) 55 degrees
d) 60 degrees

Answer:

c) 55 degrees

Explanation:

This inclination is also done so there is less inclination and extension of the neck since the patient ends up with the OML (orbitomeatal line) more perpendicular to the IR plane.

Entre los siguientes métodos de separación de mezclas, Jorge debe seleccionar el adecuado para separar sal de una mezcla de sal
makvit [3.9K]

Teniendo en cuenta las definición de evaporación, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.

El método de separación utilizado para el agua y la sal es: la evaporación.

La evaporación consiste en pasar el soluto disuelto en un liquido a estado gaseoso y ocurre al aumentar su temperatura de forma natural o artificial,. Dependiendo de que se desea evaporar se utiliza el material correspondiente. La técnica mas común es por contacto y puede acelerarse si utilizamos un material conductor dentro del liquido.

En otras palabras, se conoce que la evaporación es el proceso por el cual las distintas moléculas en estado líquido, como lo es en agua, pasan a un estado gaseoso de manera espontánea, siendo este el principal efecto de la evaporación.

Como se mencionó el método de separación utilizado para el agua y la sal es la evaporación. Durante este proceso, al aplicar calor, el agua se convierte en vapor y se libera al aire. La sal, como tiene otro punto de ebullición, no se evapora.

Entonces, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.

Which technique involves injecting an animal with a radioactive molecule to see which part of the olfactory bulb is most activat
Rudiy27

The asnswer is 2DG also known as 2-Deoxy-D-glucose.  2DG is a glucose molecule that has the 2-hydroxyl group replaced by hydrogen, so that it cannot undergo further glycolysis. As such; it acts to competitively inhibit the production of glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of glycolysis).

How many 02 molecules are required for two glucose molecules to undergo cellular respiration?
jekas [21]
Answer: 12

Explanation: the reaction is: C6H12O6 + 6 H2O + 6 O2 -> 6 CO2 + 12 H2O + 38 ATP + heat
Because of the 2 glucose molecules you multiply the stoichiometry with a factor 2 so: 2 x 6 O2 = 12 O2

In a population with two alleles, B and b, the allele frequency of B=0.59. What would be the frequency of the heterozygotes if t
Levart [38]

Answer:

0.483

Explanation:

The given population is in Hardy-Weinberg equilibrium. If the gene has two alleles, the sum total of the frequencies of these two alleles will be one.  

Therefore, the total of the frequency of allele B and frequency of allele b will be 1. f(B) + f(b)=1

If the frequency of allele "B" is 0.59, then the frequency of allele "b" will be=1-0.59= 0.41

The frequency of heterozygous genotype in the population= 2pq

p= frequency of the dominant allele

q= frequency of the recessive allele

So, 2pq= 2 x 0.59 x 0.41 = 0.483
