Explanation:
What are the 6 regions of the
human body from which hair can
be derived?
Answer:
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. ... Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life, if that answers your question.
Explanation:
The six (6) regions of the human body from which hair can be derived are:
1. Head.
2. Eyebrow.
3. Beard.
4. Pubic area.
5. Body.
6. Armpit (underarm).
Hair can be defined as a threadlike, keratinous filament that typically grows out of the epidermis. Also, an epidermis is the outer layer of the skin.
Basically, the hair comprises two main parts and these are:
The follicle.The hair shaft.Some of the macroscopic and microscopic properties of hair include:
Hair length.Hair color.Pigmentation of the cortex.Types of scales on the cuticle.Hair curliness.Pattern of the medulla.Generally, hair can be found or grow in different regions of the human body and these include the following:
1. Head.
2. Eyebrow.
3. Beard.
4. Pubic area.
5. Body.
6. Armpit (underarm).
7. Eye lash.
8. Nose.

Which of the following is true?
The flow of gases varies directly with airway resistance.
As lung compliance increases, the energy required to breathe increases
Surfactant increases the cohesiveness of water molecules therefore decreasing
the surface tension of the alveolar fluid.
Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

In mammoths, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a mating between a heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth. Give genotypic and phenotypic ratios of offspring.
Answer:
Genotypic and Phenotypic ratios → 1:1:1:1

F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.
