How do hormones influence human behavior? (22 marks) Adrenaline comes along with a term called “fight or flight” it is used when the body is under stressful situations. It is an adaption the body human body has gone through to react to danger quickly. When under the adrenaline rush the body allows more oxygen into the lungs at a faster rate‚ it increases physical performance for a short period of time and there is a rush of blood to the main body organs that help deliver this quick reaction which

Overview on Tissue Epithelial Tissue: Epithelial tissue is one of the four major tissue type in the body. It covers the whole surface of our body. The tissue is specialized to form a covering or lining of all internal and external body surfaces. Your skin is composed of epithelial tissue. It also lines your body’s cavities and major organs. If its two or more cells thick such as think skin‚ its known as stratified epithelium. Simple epithelium can be subdivided accordingly to the shape and function

series of biological‚ or physical‚ transformations‚ the process can also have an effect on the psychosocial and emotional development of the adolescent. Puberty is initiated by hormone (which are chemicals) signals from the brain to the gonads (the ovaries and testes). In response‚ the gonads produce a variety of hormones that stimulate the growth‚ function‚ or transformation of brain‚ bones‚ muscle‚ blood‚ skin‚ hair‚ breasts‚ and sex organs. Growth accelerates in the first half of puberty and

5: Anatomy and Physiology Topic: Types of tissues Date: 09/06/2015 Objectives : Exploring four types of tissues. and Comparing four types of tissues : Nervous‚ Connective Epithelial‚ and muscular tissues. From Tissues to organs Cells combine to form tissues and tissues combine to form organs. Cells combine to form four primary tissues: - Epithelial tissue - Connective tissue - Muscle tissue - Nerve tissue BACKGROUND:A tissue is a group of cells that have a similar shape

Excellent; I couldn’ t have written a better paper myself. DIVERSITY OF PLANTS Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago‚ trees had evolved and formed forests‚ within which the diversification of vertebrates‚ insects‚ and fungi occurred. Roughly 266‚000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes

Introduction Man has propagated plant material almost as long as he has cultivated the land to produce food. For a long time‚ plant material was propagated mainly by using the seeds of existing plants. Better methods were discovered over time‚ methods that allowed the farmer to retain the desirable qualities of the plant material‚ while eliminating some of the less desirable qualities. Through these methods‚ the farmer was also able to eliminate the variations between plants of the same cultivar and produce

The Main Body Tissues Introduction Tissue just means a group of cells that together carry out a particular job in your body. There are four different types of tissue within the human body. This consists of the connective tissue‚ the epithelial tissue‚ the muscle tissue and the nervous tissue. Each of these tissues are vital for our bodies and each tissue has a very important role to fulfil. Epithelial tissue Epithelial tissue protects your body from moisture loss‚ bacteria‚

Complex permanent tissue A complex permanent tissue may be classified as a group of more than one type of tissue having a common origin and working together as a unit to perform a function. These tissues are concerned with transportation of water‚ mineral‚ nutrients and organic substances. The important complex tissues in vascular plants are xylem‚ phloem. Complex permanent tissue is heterogeneous tissue which is formed of two or more than two types of mature cells of common origin which coordinate
