Un grupo de estudiantes utilizan un aparato para estudiar la tranferencia de energia durante la reaccion quimica entre pedazos de cascara de huevo( carbono de calcio) y vinagre(acido acetico). Durante el experimento utilizan la misma masa de cascara de huevo pero varian la concentracion del vinagre, (1%, 3% y 5%). Contesta:1. Explica por que la transferencia de energia no es la misma entre las tres pruebas del experimento.2. Describe como se podria modificar el aparato para que pueda medir con MAYOR EXACTITUD la tranferencia de energia en cada reaccion

Explanation:

It correctly reads;

A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%).

1. Explain why the energy transfer is not the same between the three tests of the experiment.

2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
