Ways that plants cope with saline environments Introduction There are a lot of plants in this world managed to grow in different kind of environments by adapting to those environments in certain ways. In this essay‚ plants grow in environment with different salinity are concerned. Plants can be divided into two different groups when it comes to salinity. The first type of plants is the plants that grow and reproduce in saline environment which are called halophytes (Jefferies. 1981). Whereas

Title: The effect on the human population of a global infection AIDS stands for Acquired immune deficiency syndrome. AIDS is caused by a virus known as HIV‚ the human immunodeficiency virus. If HIV is contracted the body will begin to make anti-bodies in order to fight the infection‚ if these antibodies are found in the blood the person is known as HIV-positive. HIV causes the immune system to weaken which leads to opportunistic infections that can make the compromised host sick due to the weak

blocks of all living things. They are also the tiniest living organisms in the human body which provides structure for the body and intake nutrients that become energy. Cell membranes control what goes in and out the cell‚ it protects it. The lipid bilayer describes the membrane of both animal and plant cells where the properties that make up phospholipids are very important to the cell membrane function‚ it has protein which is dispersed properly and it mainly functions in the selective transport

Introduction Retroviruses are a family of enveloped RNA viruses that are defined by their common characteristics in structure‚ replication properties and composition. The viruses range from 80-100 nm in diameter and have an outer lipid envelope composed of viral glycoproteins. The structure and location of their inner protein core is a specific characteristic to the members in this family of viruses. In addition‚ the replication strategy‚ known as reverse transcription‚ of the

Homeostasis literally means “same state” and it refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed. The importance of this cannot be over-stressed‚ as it allows enzymes etc to be ‘fine-tuned’ to a particular set of conditions‚ and so to operate more efficiently. Much of the hormone system and autonomic nervous systems is dedicated to homeostasis‚ and their action is coordinated by the hypothalamus. In Module 2 we saw how

simultaneously and independently. The cell membrane of the plant cell has a phospholipid bilayer. Plant cells often have a central vacuole‚ which is a large membrane-bounded sac that stores proteins‚ pigments‚ and waste materials. The central vacuole‚ in most mature plants‚ occupies a major portion of the internal volume of the cell and has a phospholipid bilayer. Inside the nucleus‚ an organelle with a phospholipid bilayer that regulates cell activity‚ the DNA is wrapped tightly around proteins and packaged
