Question
Chapter 5, Problem 16STP
Summary Introduction
To write:
The reason why two species involved in a symbiotic relationship probably evolved at around the same time.
Introduction:
Symbiosis can be defined as a close relationship between two organism, in which one of the species gets benefit and the other species may or not. The relationship may be positive, negative, or neutral. Mutualism is a symbiotic, which benefits both the species. Commensalism is a symbiotic relationship in which one of the species is unaffected and the other species takes benefit from the other
Expert Solution & Answer
Explanation of Solution
Natural selection is the main key to know how symbiosis evolves. Most symbiotic relationships probably initiate as facultative. Over many generations, the organisms came to depend more on the symbiosis because natural selection helped those traits and not others. For example,
Conclusion
Symbiotic relationships are necessary because they are a main driving force of evolution. This bonding and cooperation among species help them to survive better than they would as individuals.

- 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.
