Investigating the effect of surface area to volume ratio on Osmosis As far as living organisms are concerned‚ they are all made up of cells whereas‚ the membrane surrounds all those cells. The cell membrane has the key responsibility to maintain a stable interval environment. Even though‚ Cell membrane is made up of phospholipids bilayer and has that great amount flexibility making it unbreakable while transportation of substances. However‚ certain substances such as‚ dissolved gases‚ sugars‚ salt

Question 1 Surface level diversity Surface level diversity are those differences that are easily noticeable such as age‚ gender‚ ethnicity/race‚ culture‚ language‚ disability etc. Surface level diversity is easy to be measured and managers/recruiters can fall into the wrong practice of discrimination based on these factors. For example‚ thinking that performance degrades with age‚ they might prefer younger workforce. Surface level diversity is often difficult to change. For e.g. racial differences

Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs

of gravity and the type of surface was tested through a series of experiments. In lab 4.1‚ the force of gravity was tested through various surface types‚ including: tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sand paper. In lab 4.2‚ two different surface types that were tested included: tabletop and coarse sand paper. This lab compared the two averages between both tabletop and coarse sandpaper using different amounts of blocks. In lab 4.3‚ the surface area of the blocks sliding

Surface Tension of Water I. Purpose How does adding soap to water change its surface tension? II. Background Adhesion is the bond between two substances of different makeups. In water‚ adhesion allows it to stick to other surfaces. Cohesion is the bond between two of the same substances. A hydrogen bond is a type of cohesion in water in which the hydrogen atoms of one water molecule being attracted to the oxygen atom of another water molecule. In water‚ each molecule in the middle is pulled

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic
