Concept explainers
To explain: The balanced stomatal opening and closing trade-off.
Introduction: Stomata are tiny pores commonly found on leaves and stems. The stomatal pore has a border made by a pair of guard cells. The guard cells are made of thick parenchymal cells that control the stomata to open and close. The functions of stomata include gaseous exchange and transpiration.

Explanation of Solution
Stomatal trade-off occurs mainly for processes such as transpiration and photosynthesis. During photosynthesis, the pores are opened for gaseous exchange and stomata are opened because of photosynthesis. It is closed in the night to prevent water loss. In conditions of drought stomata are closed during the day to conserve water. During exchange of gases when carbon dioxide (CO2) levels are high stomata opens while in low
CO2 levels it closes. The cellular potassium ions also play a role wherein an increase opens the stomata while a decrease closes the stomata.

Steroids diffuse through membranes without transporters. Compare and contrast the remaining substances and circle the three substances that can diffuse through a membrane the fastest, without a transporter. Put a square around the other substance that can also diffuse through a membrane (1000x slower but also without a transporter).

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
