The Waldorf family was caught in a fire but escaped. Unfortunately, the father and daughter suffered burns. The father had secon

d-degree burns on his entire chest, abdomen, and both arms, and third-degree burns on his entire left lower extremity. The daughter suffered first-degree burns on her whole head and neck and second-degree burns throughout both lower extremities.
a. What percentage of the father's body was covered by burns?
b. What percentage of the daughter's body received first-degree burns?
c. What part of the daughter's body has both the dermis and epidermis involved?
d. The father experiences a good deal of pain in the area of the chest and abdomen, but little pain in the leg. Why?

Answer and Explanation:

The father had 54% of the body covered by burns, since a little more than half of his body was burned. In addition, to calculate the percentage of body burn, the following values are considered: head, arms and legs - 9% torso front - 18% torso back - 18%. In addition, the father feels little pain in his legs (which had worse burns) because the third degree burn destroys the nerve endings, while the second degree burn only damages these endings promoting intense pain.

The daughter had 9% of her body burned by first degree burns, which corresponds to her lower limbs. These burns involve the skin and the epidermis, for this reason, we can say that the legs are the part of the daughter's body that has compromised hair and epidermis.

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father
prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.

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.

Which trophic level contains more energy: a trophic level of herbivores or a trophic level of carnivores? Why?
Bas_tet [7]
Hello :)

The answer to your question is a trophic level of carnivores


Only a fraction of the energy available at one trophic level is transferred to the next trophic level.

Since carnivores are above herbivores in the trophic levels, herbivores have more energy than carnivores.

Hope this helps and have a great day!
