Answer: fibrous periosteum

The diaphysis is the main shaft of a long bone which is made up of cortical bone which contains bone marrow and fats. It is covered by a fibrous connective tissue called the fibrous periosteum. The cells in this layer are densely packed and contain blood vessels, nerve endings and lymphatic.

The fibrous connective tissue that makes up the outside covering of the diaphysis is the periosteum.
It is a dense membrane composed of fibrous connective tissue that closely wraps all bone except that of the articulating surfaces in joints, which is covered by a synovial membrane. It serves as an outside covering or protection.

Explain the biological structure hierarchy of the human body and the role of homeostasis in maintaining the body. Include the fo

Nuetrik [128]

Answer:

1. Biological structure of the human body

The human body is organized in different levels according to their complexity.

The levels are the folowing (increasing complexity).

1. Atom (N, O, C,..)

2. Molecule (Protein, lipids, water...)

3. Organelle (mitochondria, golgi apparatus,...)

4. Cell (blood cells, bone cell,..)

5. Tissue (connective tissue, epithelial tissue,..)

6. Organ (lungs, kidney,..)

7. Organ system (skeletal system, muscuar system,...)

8. Organism (the human body)

Each of the levels is formed by an agrupation of the previous level. For example, cells are formed by a number of organelles, and a group of cells form a tissue.

Cells are the basic units of structure of the body, and there are different types of them.

2. Homeostasis

Homeostasis is a process of the body by which the organism works to maintain a stable internal environment, while adjusting to changes in the external environment.

This process is possible because of the work of both the nervous system and the endocrine system. While the first controles the body's activities and detects the necesity of adjustments, the second regulates the activities by using hormones.

Contrast the three types of heat transfer

topjm [15]

Answer:

There are three modes of heat transfer.

1. Conduction

2. Convection

3. Radiation

1. Conduction: Heat transfer through the process of conduction occurs in substances which are in direct contact with each other. It generally takes place in solids.

For example: When frying vegetables in a pan. Heat transfer takes place from flame to the pan and then to the vegetables.

2. Convection: In this process, heat is transferred in the liquid and gases from a region of higher temperature to a region of lower temperature. Convection heat transfer occurs partly due to the actual movement of molecules or due to the mass transfer.

For example: Heating of milk in a pan.

3. Radiation : It is the process in which heat is transferred from one body to another body without involving the molecules of the medium. Radiation heat transfer does not depend on the medium.

For example: In a microwave, the substances are heated directly without any heating medium.

What is the advantage of the gram stain over the simple stain?

Natali5045456 [20]

Gram staining identifies different bacteria types and it separates bacteria into two groups (gram negative and gram positive) based on their cell wall constituents through the use of different special dyes. Simple staining involves the use of a single stain solution and is unable to identify the exact organism.
