Answer to Problem 1NV
The given blanks can be filled as follows:
S. no. | Correct term |
1 | Melanin |
2 | Sebaceous gland |
3 | Keratin |
4 | Hair follicles |
5 | Epidermis |
6 | Dermis |
Explanation of Solution
Melanin is a pigment that is present in skin cells. This pigment is brownish in color and has the capability to absorb the harmful ultraviolet radiation.
Sebaceous glands or oil glands are responsible for the production of natural oils that maintains the outermost layer of skin and keep the hair follicles healthy.
Keratin is a protein that is found in the outer layer of the skin. This protein forms a coat on the skin and makes the skin waterproof as well as protects the tissues underneath.
A hair follicle is a narrow groove that serves as a root for the hair and it is the portion of the skin from where the hair grows.
Epidermis is the outermost thin layer of skin that is made up of dead keratinized cells. This layer protects the soft structures and tissue present beneath it. Below the epidermis, a layer called dermis is present; it is thicker and soft.

Steroids diffuse through membranes without transporters. Compare and contrast the remaining substances and circle the three substances that can diffuse through a membrane the fastest, without a transporter. Put a square around the other substance that can also diffuse through a membrane (1000x slower but also without a transporter).

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.

Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forward
