Asthma is a condition of the respiratory which is caused by the tightness of the muscles in the airways‚ which therefore causes the individual with this condition to breathe out reduced amount of air which then leads to difficulty in inhaling and exhaling. According to the World Health Organization (2010)‚ this condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack‚ the lining

living organisms and to begin understanding life‚ we must realize the cell’s structure‚ whether it is about the different types of cells or how the cell functions. Biology is the study of life and for the human species; the cell is the most basic principle of life‚ which is why it is so important to understand the complexities of cells. There are two basic categories of that all cells fall under. They are prokaryotic cells and eukaryotic cells. Prokaryotic cells are single-celled organisms that

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between

cloning – reproductive cloning‚ therapeutic cloning and DNA cloning. 2 Reproductive cloning is type of cloning where genetic material from donor cell is taken and put into egg cell of surrogate mother. 3 Then‚ the egg cell is put into uterus of host organism‚ and with usage of mild electric shock is forced to divide‚ so producing embryo. 4 This process results in the creation of new animal. In 1996‚ Scottish scientists announced that first animal was cloned. It was sheep – Dolly. 5 Even though this process

Using these laws‚ scientists studied the characteristics of organisms for most of the next one hundred years following Mendel’s discovery.
