Question
Chapter 25.3, Problem 1NV
Summary Introduction
To define:
The term mantle, radula, gills, open circulatory system, closed circulatory system, nephridia, and siphon.
Expert Solution & Answer
Explanation of Solution
Mantle is an outermost covering of internal organs of molluscs. It plays an important role in molluscs and attachment of the internal body to external shell.
Radula is an organ in molluscs that is used by them to scraping food of the rocks.
Gills are the part of respiratory system of some aquatic animals and help in delivery of oxygen and removal of carbon dioxide.
Open circulatory system is a type of respiratory system, in which the blood and the body fluid surrounding the tissues are in direct contact.
Closed circulatory system represents isolated circulatory circuit in some animals, where the blood flows in flood vessels and mixing of the blood with interstitial fluid does not takes place.
Nephridia are tubules that are involved in the excretion of nitrogenous wastes and osmoregulation.
Siphon is a tube which is part of mollusc’s mantle and help in exchanging fluid from the external atmosphere.

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.

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.
