Mrs. Fender's jaundice is caused by the accumulation of bilirubin in her blood and tissues. What is the normal fate of bilirubin
vfiekz [6]

Answer:

Jaundice is a symptom of cirhosis which is related to the chronic liver disease

Explanation:

Bilirubin is produced in the body when the hemoglobin protein in old red blood cells is broken down. Erythrocytes continuously undergo a (breaking apart) process.  As the red blood cells disintegrate, the hemoglobin is degraded or broken into globin (the protein part), iron, and heme. The heme first breaks apart into biliverdin, a green pigment which is immediately reduced to bilirubin, an orange-yellow pigment. The bilirubin is then transported to the liver where it reacts with a solubilizing sugar called glucuronic acid. This more soluble form of bilirubin (conjugated) is excreted into the bile. The bile passes through the gall bladder then goes into the intestines where the bilirubin is converted into a variety of pigments.

Jaundice occurs when the diseased liver doesn't remove enough bilirubin, a blood waste product, from your blood. Cirrhosis, when in its late stages, can cause Jaundice. Cirrhosis occurs as a result of severe scarring of the liver caused by chronic liver disease. As a healthy liver tissue becomes damaged over time, it is replaced by scar tissue, which affects the structure of the liver and decreasing its ability to function.

If you wanted to sequence the genome of Ötzi, the 5,300-year-old "Iceman" mummy found in the Alps in 1991, which method would yo
Delvig [45]

The question is incomplete as it does not have the options which are:

a) DNA

b) AGCT

c) PCR

d) SNP

Answer:

PCR (polymerase chain reaction)

Explanation:

The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.

The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.

In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.

Thus, PCR is correct.

Ella filled a bucket 7/10 of the way with water. She then poured out 2/10 of the water. How much water remains in the bucket?
Ainat [17]
Answer: 1/2
----
To do this problem, you'll have to subtract fractions. To subtract fractions, find a common denominator on both fractions (if needed, which you don't need to do for this problem!), subtract the numerators, and put the difference over the common denominator. Simplify if needed. 

Ella started out with 7/10 a bucket of water and then lost 2/10 by pouring it out. That means you're finding the difference of 7/10 - 2/10!

1) Find a common denominator
This is already done because both fractions have "10" in the denominator.

2) Subtract the numerators
7 and 2 are the numerators and you're subtracting 2 from 7:
7 - 2 = 5

3) Put the difference of the numerators over the common denominator
\frac{difference}{common \:demoninator}  =  \frac{5}{10}

4) Simplify if needed
\frac{5}{10} =  \frac{1}{2}
This is because you can divide both the numerator and denominator by 5/5 (and remember 5/5 is the same as 1, and dividing any number by 1 equals itself!)

How many and what type of chromosomes would be expected in a karyotype of a human male
aleksklad [387]

Answer: 22 pairs of autosomal chromosomes, 1 Y chromosome, and 1 X chromosome

Explanation:

The chromosomes pair are found in same number in both males and females. The male have XY chromosome and 22 pair of autosomes.

The XY pair of chrmosomes are known as sex chromosomes which decides the person is male or female.

The karyotype of the male person will have 22 pair of autosomes and a pair of sex chromosomes XY.
