Chapter 11, Problem 1.1A
Summary Introduction
To match:
Match the given structures with their respective descriptions and functions.
Introduction:The skin consists of three layers as epidermis, dermis and subcutaneous tissue or hypodermis. The epidermis layer is the outer most and protective layer of the skin, dermis contains hair follicles, glands and connective tissue and the hypodermis or subcutaneous layer is made up from fat and connective tissue.
Expert Solution & Answer
Explanation of Solution
| Column A | Column B |
| Apocrine sweat gland | 3. Became active at puberty in axillary and groin region |
| Arrector pili muscle | 12. Causes hair to stand on end and goose bumps to appear |
| Dermis | 5. Inner layer of skin |
| Epidermis | 7. General name of entire superficial layer of skin. |
| Hair follicle | 11. Tubelike part that contains the root f the hair |
| Keratine | 9. Tough protein of nails and hair |
| Melanin | 4.External pigment |
| Merocrine sweat gland | 6. Responds to elevated body temperature |
| Sebaceous gland | 8. Gland that secretes oily mixture |
| Sebum | 1.Oily secrectionthat helps to waterproof body surface |
| Stratum basale | 10. Cell division and deepest layer of epidermis |
| Stratum corneum | 2. Outer most layer of epidermis |
- Apocrine sweat gland-Became active at puberty in axillary and groin region .apocrine glands mainly found in armpits become active at puberty and produce sweat due to strong emotions,exercise,stress etc.
- Arrector pili muscle- Small muscles attached to hair follicles are arrector pili muscles and due to contraction in these muscles makes hair to stand and reflects as goose bumps.
- Dermis- Inner layer of skin consist of foillicles, glands, connective tissues etc.
- Epidermis- Outer most layer of skin protects from infection, pollutants, toxins etc.
- Hair follicle-Part of skin through which hair grows is hair follicle.
- Keratine- Keratine is a protein mainly found in hair, skin and nails
- Melanin- A skin pigments that makes nails, hairs and eyes dark in colour is melanin. <
- Merocrine sweat gland −Thoseglands that helps in reducing body temperature or thermoregulation through perspiration is merocrine gland.
- Sebaceous gland- The gland in mammals skin producing oil and usually attached to hair follicle called sebaceous gland.
- Sebum- sebum is a oily substance light yellow in color secreted from sebaceous gland helps in moisturizing the skin.
- Stratum basale- The deepest layer of epidermis made up of columnar or cuboidal cells.
- Stratum corneum- The outer most layer that contains keratin and keratinized cells.

You have returned to college to become a phylogeneticist. One of the first things you wish to do is determine how mammals, birds, and reptiles are related.
Like any good scientist, you need to consider all available data objectively and without a preconceived “correct” answer. In pursuit of that, you should produce a phylogenetic tree based only on morphological features that show birds and mammals are more closely related. You will then produce a totally different tree, also using morphological features, that shows birds and reptiles are more closely related. Do not forget to include all three groups in both your trees.
Based solely off the trees you produce, which relationship would you consider the more likely and why? Once you have answered that question, provide a brief summary of the “modern” understanding of the relationship between these three groups.
true or false, the reason geckos can walk on walls is hydrogen bonding between their foot pads and the moisture on the wall.
Biology laboratory problem
Please help. thank you
You have 20 ul of DNA solution and 6X DNA loading buffer solution. You have to mix your DNA solution and DNA loading buffer before load DNA in an agarose gel. The concentration of the DNA loading buffer must be 1X in the DNA and DNA-loading buffer mixture after you mix them. For that, I will add _____ ul of 6X loading buffer to the 20 ul DNA solution.
