Why were physical activity and caffeine and alcohol intake the controlled variables? Because you can control on the amount of time you spend doing physical activities and the intake of both caffeine and alcohol. 5. What type of assay was used to measure plasma glucose and ketone levels?
Part 2: Calibrating a Dropper 1. The number of drops in 1 mL water (drops used to move from the 1.00 mL to 2.00 mL mark): Trial 1: 23 drops Trial 2: 22 drops 2. The number of drops on average per one milliliter: 22.5 Part 3: Calculating the Number of Molecules 1. The diameter of the circle formed (cm): 1 cm Calculations 1. Calculate the surface area of the circle formed (πd2/4): Surface area = .785 cm2 2.

The goal is to meet my DRI 100% so if I ate more animal products such as eggs and dietary products (cheese) I would increase my intake of vitamin A. For thiamin, my DRI was 1.1 mg. My intake was .07 mg, which is an intake of 66.0%. When inadequate amounts of thiamin are consumed, the deficiency affects the nervous and cardiovascular system. It can cause symptoms such as a rapid heartbeat and enlargement of the heart. I could increase my consumption of thiamin by eating products such as chicken or whole-wheat bread.

The dependent variable is the rate of osmosis. The question is how does sucrose concentration affect the ratio of Osmosis? My hypothesis is as the sucrose concentration increases the rate of Osmosis will increase. MATERIALS & METHODS When conducting this experiment, we filled 4 presoaked tubes with glucose. Each tube contained a certain amount of glucose in order to distinguish a difference between each membrane first tube contained 0M of sucrose concentration and the second strip, 0.25M of sucrose concentration.
