Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

These biological dynamics influence when and how anxiety disorders emerge and begin to cause distress in the individual. An anxiety disorder is an “unfounded fear or anxiety that interferes with day-to-day functioning and produces clinically significant distress or life impairment” (Sue et al.‚ 2013‚ p.?).

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

General Psychology May 8‚ 2014 Biological Factors of Homelessness Sheila McKehnie said‚ “People who are homeless are not social inadequates. They are people without homes.” This illustrates the important point that we cannot dismiss a person’s human dignity simply because he or she lives on the street. On the contrary‚ we need to acknowledge their equality and think about the endless factors that could have put these people on the streets. There are many biological and social factors that can lead

Discuss two biological explanations of depression (8+16 marks) AO1: One biological explanation for depression is family studies. Family studies have proved that having a first-degree relative with depression appears to be a risk factor of depression. These studies select people who already have the depression (the probands) and examine whether other members of their family have been‚ or might be diagnosed with depression. Research has found that around 20% of such relatives have depression compared

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water? Water
