Mucous membrane

bacterium consists of a double membrane and is helically shaped (1). One of the membranes is an inner membrane and the other membrane is the outer membrane, also consisting of a protoplasm that is generally cylindrical and long. The most unique feature of the Borrelia burgdorferi is its ability to travel easily through its host’s fluids and tissues by using their highly adaptive flagella (2). The flagella in most spirochetes is found in the periplasm between the diderm membranes. It has a…

there is two layers of the phospholipids the heads stick out and the tails touch each other staying away from the water. The proteins divide the group of phospholipids from each other. There are three variables that effect moving across the cell membrane. First is the solubility, if it is soluble it can easy move across and if it is not then it will have a harder time moving across. The size effects it as well the bigger the object the harder it will be. The smaller it is will make it easier for…

diffusion. Osmosis is diffusion of water. Tonicity compares the environment inside of a membrane with the outside. When a membrane bound structure has a higher concentration of water on the outside of the membrane than the inside is hypotonic. Hypertonic is when a membrane bound structure has a higher concentration of water on the inside of the membrane than the outside. When something is isotonic the inside of the membrane has the same concentration as the outside of the structure. If water…

History All plants need water, but plants may prefer one type of water over another. There are two main types of water, tap water and rainwater, and each type of water has its pros and cons. Different plants need different amounts of water. Along with that, some plants also need water more frequently. This writing is going to explain about how plants prefer one type of water over another. There are many chemicals added to tap water. The uses of these chemicals is to disintegrate any dirt in the…

Within the human body, the natural process of moving soluble molecules across a membrane is referred to as passive transport. For this type of transport chemical energy is not necessary. Two of the main types of passive transport that the human body utilizes are osmosis and diffusion. Diffusion is the movement of a hydrophobic substance across a semi-permeable membrane without the use of cell energy from a gradient area of higher concentration to an area (either inside or outside of the cell)…

Membrane Potential in the RMP The membrane potential in the Resting Membrane Potential, or the RMP, is the little bit of voltage or electrical potential going across from the membrane of its regular resting voltage. This is caused because of gradients that make the ions go across the membrane of a cell through ion channels because ions are not soluble so they have to go through channels. These channels are called ion channels that are watery pores allowing ions to get through according to their…

effects on the porosity in potatoes is by the dehydration process. The removal of water during the rehydration process causes the cell to rupture due to stresses subjected to the cell membrane and cell wall of the potatoes. In addition, the stresses (usually generated by the water vapor) subjected to the cell membrane and cell wall will produce the pressure towards the food's cavity surfaces resulting in the increase of porosity of the product (Singh. F et. al, 2014). Therefore, it can be said…

blood plasma. This binding to the plasma proteins can play a significant role in determining drug distribution. This binding also plays a role in drug dynamics in that only the unbound or free drugs interact with the receptors and penetrate the cell membranes. Albumin along with others (i.e. lipoproteins, al-acid-glycoprotein) help with the binding process. As a result of this process, the drug that is bound is maintained in the blood stream while the unbound components are excreted or…

1) What is a difference between endotherms and ectotherms? The difference between an endotherm and an ectotherm is how their body is composed for regulating body temperature. This is important, as body temperature is key to maintain homeostasis. While ectotherms must rely on outside variables to regulate body temperature endotherms can regulate body temperature using mechanism within their own body. A major adaptation in endothermic organisms that is not seen in ectotherms is the large number…
