a.
To describe:
If each grasshopper passes hundred Kilocalories to the cardinal when eaten, how many grasshoppers would the cardinal have to consume to get 10,000 Kilocalories?
Concept introduction:
An energy pyramid is characterized by the amount of energy available to organisms in an ecosystem. The energy pyramid consists of various levels. Each level coincides a stage in a food chain and it is known as a trophic level. At every trophic level, a certain amount of energy taken by the producers is lost as heat, particularly during
b.
To describe:
How many Kilocalories of grass are necessary to generate 10,000 Calories worth of grasshopper?
Concept introduction:
An energy pyramid is characterized by the amount of energy available to organisms in an ecosystem. The energy pyramid consists of various levels. Each level coincides a stage in a food chain and it is known as a trophic level. At every trophic level, a certain amount of energy taken by the producers is lost as heat, particularly during cellular respiration. Approximately, 10 percent of the energy at each trophic level has moved to the subsequent trophic level.

To describe:
Where does the lost energy go?

- QUESTION 8 For the following pedigree, assume that the mode of inheritance is X-linked recessive, and that the trait has full penetrance and expressivity and occurs at a very low frequency in the hum population. Using XA for the dominant allele and Xa for the recessive allele, assign genotypes for the following individuals (if it is not possible to figure out the second allele of a genotype, that with an underscore): 2 m 1 2 1 2 4 5 6 7 8 9 IV 1 2 3 5 6 7 8 CO 9 10 12 13 V 1, 2 3 4 5 6 7 8 9 10 11 12 13 a.

Goal 1: To alleviate the client's overall level, frequency, and intensity of anxiety and PTSD symptoms so that daily functioning remains unimpaired. Objective 1: The client will learn and regularly use at least two anxieties management techniques to reduce anxiety symptoms to less than three episodes per week. Intervention 1: The therapist will provide psychoeducation about anxiety and PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.arrow_forwardO Macmillan Learning You have 0.100 M solutions of acetic acid (pKa = 4.76) and sodium acetate.
