which all life forms depend is visible light from the sun. Light energy must first be transformed into chemical(bond) energy before it can be utilized by the living cell. This transformation is achieved only in the cells of green plants and certain bacteria. In green plants it is coupled with a transformation of matter in which relatively low-energy compounds, carbon dioxide and water, are converted into high energy chemical molecules that become subunits of carbohydrates. There are four different pigment

Question 1. What is the effect of changing lambda (λ) in the discrete model, and r in the continuous model? What is the effect of changing N0 in both models? (2 marks) When in discrete mode, a change in lambda (λ) will change the growth rate of the species. If λ increases, so does the growth rate and if λ decreases, as will the growth rate. However, the growth rate only increases if the number is above 1. 1 itself indicates no growth and below one is negative growth. The same principle applies to

Cells are the basic structural of all living things. The human body is poised of trillions of cells. They give structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain

Question 1 Most insects use external sources of heat to achieve their operative temperature range. Heinrich's research on the sphinx moth (Manduca sexta) indicates that some insects can thermoregulate by using their flight muscles and: A. using their blood as a coolant. B. decreasing their metabolic rate. C. possessing an internal respiratory system. D. using a countercurrent heat exchange mechanism. Question 2 The thermal stability of aquatic environments is a result
