Question
Chapter 5, Problem 7A
Summary Introduction
Introduction:
Biodiversity is the variety of life in an area that is determined by the number of different species in that area. Biodiversity increases the stability of an ecosystem and contributes to the health of the biosphere. There are three types of biodiversity that includes ecosystem diversity, species diversity and genetic diversity. It is important to provide biodiversity because it provides many services either directly or indirectly.
Expert Solution & Answer
Answer to Problem 7A
Correct answer:
Option (C)
Explanation of Solution
Explanation correct answer:
Option (C) Flood protection is an example of indirect economic value. An indirect economic value is a service provided by organisms not requiring harvesting. A healthy biosphere provides protection against floods and droughts, generates and preserve healthful fertile soil, detoxify and decompose wastes and regulates local climates.
Explanation incorrect answer:
A direct economic value means it is harvested directly from an organism. Human depends on plants and animals as they provide food, clothing, energy medicine and shelter.
Option (A) Food requires harvesting from organisms.
Option (B) Clothing requires harvesting from organisms.
Option (D) Making medicines require harvesting from organisms.

- *Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below.

- 9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forwardNormal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6.
