Summary Introduction
To analyze:
Three important adaptations that allow plants to reduce water loss.
Introduction:
Water is an important component in almost all reactions carried out in a living organism and hence plants also require water. Since they cannot move to different places, they have developed some adaptations that prevent water loss from the leaves.

*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. Note that carriers are not
indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis
allele, and the letter "n" for the normal allele.

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_forward
