Description To investigate whether temperature will damage and denature the permeability of plasma membrane. Preview TITLE The effect of temperature on the cell membranes of Beetroot cells. OBJECTIVES To investigate whether temperature will damage and denature the permeability of plasma membrane. HYPOTHESIS An increase in temperature will damage and denature the permeability of plasma membrane. INTRODUCTIONS Beetroot The beet (Beta vulgaris) is a plant in the Chenopodiaceae family

postsynaptic ending that has receptors sites for the neurotransmitters‚ and a synaptic cleft. When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors. The receptors that alcohol binds to are the ones for acetylcholine‚ serotonin‚ gamma aminobutyric acid‚ and glutamate. The two neurotransmitters that distress the behavior effects from alcohol are the gamma aminobutyric acid and glutamate.

the effect of different concentrations of ethanol on the permeability of beetroot cell membranes. Prediction: By exposing a membrane to a solvent‚ ethanol‚ it will increase its permeability. So the higher the concentration of the solvent‚ the more permeable the membrane will be. But if the concentration of the ethanol is beyond a certain limit‚ it may break down the cell membrane to the point where there is in fact no overall effect as the ethanol would disturb the lipids in the membrane.

Membrane Functions: Aim: To demonstrate the process of osmosis using a chicken’s egg Hypothesis: I predict that the egg’s mass after 10 min. in the 5% salt solution would increase due to and balancing out the solution. In the 10% salt solution‚ the egg’s mass would decrease since there is a high amount of salt. In the dilute water solution‚ the egg’s mass will increase‚ as the membrane would take in that water. Materials: 1- One fresh egg 2- One plastic spoon 3- One plastic fork

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

Respiratory acidosis is the result of too much carbon dioxide and not enough oxygen in the blood. This condition can be caused by chest injury‚ chronic lung disease‚ or overuse of sedatives. ABG results will show a low pH and a high PCO2‚ according to Lab Tests Online. Respiratory Alkalosis Respiratory alkalosis can occur if a patient hyperventilates. Stress‚ pain‚ or lung disease may cause this rapid breathing. Hyperventilation will result in too much oxygen in the blood and not enough carbon dioxide

means addiction of alcohol; it could explain as a person who could not stop to drink and craving for it. In fact‚ alcohol abuse can damage a person’s health and life. Alcohol would affect a person’s mind and body that causes the person did wrong thing. Besides‚ when a person drunk‚ he or she might not know what they had done. Which mean‚ when they are drunk‚ they could not judge what are right and wrong. Consequences‚ there are many cases happened because of alcohol abuse since alcohol would impact a

Biological effects of Methamphetamines Maria B. Araiza-Chavez BEH 317 Peter Pingerelli October 26‚ 2010 Abstract Biological effects of Methamphetamines Methamphetamines affect the human body in a physical and neurological and psychological way. The use of meth can lead to devastating effects to the nervous system for example leaving the user with nervous ticks and body jerks similar to a person suffering from Parkinson’s disease. On a physical level‚ the user may show skin sores and

BIO103 Environmental Biology – Effects of Alcohol on Human Coordination Introduction: Alcohol is known to produce many chronic abnormalities that are attributable to parietal lobe dysfunction. The self becomes aware of the body being a distant object but it feels a strange attachment feeling (Miller et al‚ 1991). Considerable laboratory research indicates that different levels of alcohol consumption contributes to overall behavioural and cognitive functions and therefore the reason for carrying

The purpose of this lab was to hypothesize about membrane traffic in lab‚ explain the differences between the solutions hypertonic‚ hypotonic‚ and isotonic and how they respond using the understanding of the cell membrane structure‚ types of transport mechanisms such as active‚ passive‚ diffusion‚ osmosis‚ and explain the movement of particles moving across the cell membrane. In this lab was divided into two parts. The first part was varying the concentration and the second part was varying the temperature
