Summarise the main development of a child from the age range 0-2‚ 3-5 and 5-8 years The main developments of a child are as follows: Physical Development Intellectual Development Language Development Emotional Development Social Development Here I will summarise the above points: Physical Development 0-2 years The first physical stages in a baby happen after they are born. They will start by learning how to hold their head up. Babies have a grasping reflex which enables them

Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons

Activity 1 1. Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Therefore‚ the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. 2. Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. My results went well compared to my prediction

REVIEW SHEET EXERCISE 1 Cell Transport Mechanisms and Permeability Simple Diffusion The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? NONE 1. According to your results‚ which solute had the highest molecular weight? Albumin 2. Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? Na+Cl 3. Using the data from Chart 1‚ explain the relationship between the

________________________ Chemical and Physical Processes of Digestion: Computer Simulation Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? 7.0 Why? because that is when the salivary is most effective and it breaks down carbohydrates 2. How do you know that the amylase did not have any contaminating maltose? because the sample didn’t change color. Negative sugar/IKI

Activity 1: Electrical Stimulation 1. Do you see any kind of response on the oscilloscope screen? NO 2. What was the threshold voltage‚ or the voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold voltage? The tracing travel in the same fashion but the tracing were different with an increase threshold voltage 4. What reason can you give for the change? Increase voltage 5. Record this maximal voltage here:

Activity 2 7) In addition to what you saw‚ did you detect any smells? Describe them. At what point in the observation process did you detect them? Yes. In a little far distant I smell only gasoline when the car driven around and also when filling gasoline to my car. 8) If you used the candle‚ what color was the molten wax? If you looked at something in the environment (a dog‚ bird‚ the sky‚ clouds)‚ provide details...color‚ texture‚ shape‚ size‚ etc. I believe the candle contains carbon
