Answer:
6.0221409e+23
Explanation:
The number of molecules in a mole of any substance is Avogadro's number, 6.0221409e+23.
Answer:
Displaced
Explanation:
A convenient way to measure the volume of an object is to measure the volume of a solid is to immerse the solid into water.
When a solid is immersed in water, it displaces some volume of water. This volume of water displaced is the same as the volume of the object.
For instance, if the volume of water in a measuring cylinder was 25 ml and i added a stone which made the water in the measuring cylinder to rise to 70 ml, it simply means that the volume of the object is 70 ml - 25 ml = 45 ml
Answer:
Depends on the reaction.
Explanation:
Hello,
In this case, the answer is depends on the reaction since the ratios between the rates of both consumption and formation depend upon the stoichiometric coefficients in the chemical reaction. For instance, for the reaction:
A -> 2B
The relationship is:
Therefore, we can see that the rate of consumption of A half the rate of formation of B, but is we consider the following chemical reaction:
2A -> B
The relationship is:
Therefore we can see that the rate of consumption of A doubles the rate of consumption of B.
Best regards.
Answer:
Hi
Inbreeding increases the chances of transmission to the next generation of types of inherited diseases. Our genome is made up of two copies of each gene, one inherited from our father and one from our mother. In order for autosomal recessive diseases to be found, the two copies of the gene need to be mutated. If only one of the copies is mutated and the other is not, the person is a carrier but does not manifest any of the clinical symptoms of the disease. One of these diseases is hemophilia. An example of this is Prince Leopold, he was the first real member affected by hemophilia, in this case hemophilia B. When one of the proteins necessary for blood clotting is missing, the wounds take much longer to heal. Small cuts are not usually a problem, but major injuries can cause bleeding.
The defective gene in people who suffer from this type of hemophilia is called F9, and it is located on the X chromosome. That means it has an inheritance linked to sex. Women have two X chromosomes (XX), while men have an X chromosome and one Y (XY). Since hemophilia alleles are recessive, two defective alleles are needed in women to suffer from the disease, while only one is needed in men. Therefore, the disease is much more common in men. The most frequent hemophilia is that of type A and is due to a defect in coagulation factor VIII, whose gene also has an inheritance linked to sex.
