Biology A - Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and

data. As evident in the table‚ the 10oC temperature is very accurate as the range was 0‚ resulting in an error percentage of 0%. However‚ the 35oC temperature had a no clear skew of results as indicated through the range‚ 14 and the error percentage‚ 161.47%‚ suggesting that the trials at this temperature were not very accurate as they were largely inconsistent. The 50oC also proved to have inaccuracies‚ however‚ not as significant as the previous temperature‚

In Henry IV Part II William Shakespeare uses diction‚ syntax‚ and imagery to convey King Henry’s state of mind. The King starts his soliloquy questioning why he cannot sleep when the peasants can.

DSM-IV Evaluation Case Study 1: Schizoid Personality Disorder “People with schizoid personality disorder persistently avoid and are removed from social relationships and demonstrate little in the way of emotion (APA‚ 2000)” (Comer‚ p. 398‚ 2005). Psychodynamic theorists believe schizoid personality disorder is caused by something that happened through a person’s childhood. They have been unaccepted by their parents or even abused as a young child‚ which causes a person to avoid all relationships

Procedure: The first part of this lab involved the standardization of the base NaOH with potassium hydrogen phthalate‚ or KHP. First‚ about 400 mL of NaOH (10 M) were poured into the 600-mL beaker. This was used to fill the burette. The 50-mL burette was rinsed through twice with 5 mL of NaOH. Then‚ the burette was mounted on the ring stand using a burette clamp and filled to 0 mL. Some of the NaOH was drained to fill the tip of the burette. The initial volume of NaOH‚ rounded to two decimal places

Temperature contrast between the equator and the Arctic region is greatest in the winter. Temperatures near or at the equator only change a few degrees between winter and summer while the Arctic region changes drastically up to 40 degrees between the seasons. 2. (a) Were latitude the only
