Exercise 1.1 An Experiment In this exercise you will be conducting a thought experiment. That is, you do not actually do the experiment but you will think the experiment though. Question Does talking to plants help them grow? Hypothesis A plant that is talked to will grow taller and produce larger flowers than plants that have not been talked to. Experiment Plant a seed, talk to the growing plant each day, and record how tall it grows. Observations You planted a seed and watched it grow for 3 weeks, talking to it several times a day. It grew tall with a lot of leaves and produced a beautiful flower. Question Did this experiment prove that talking to a plant helps it grow? The answer is no. List 3 reasons why this experiment failed to support the hypothesis. 1.

Nutrition and diet

We are involved in several daily activities. These actions need a significant quantity of energy. The food we eat provides this energy. Food is necessary for development, repair, and other living activities since it supplies energy. All of these are part of the living practice known as nutrition. Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists employ concepts from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body. Nutrition also looks at how people can use their diet to reduce their risk of disease, as well as what happens when they ingest too much or too little of a nutrient and how allergies emerge.
