Question
Chapter 30, Problem 7A
Summary Introduction
Introduction:
The mammals are the organism that have a hairy body in general and have mammary glands for feeding their young ones. The sweat glands and the oil glands are present in the skin of the mammals, especially humans.
Expert Solution & Answer
Answer to Problem 7A
Correct answer:
Option (A).
Explanation of Solution
Explanation/justification for the correct answer:
Option (A) hair and skin maintenance, temperature regulation and milk production. The oil glands are responsible for the production of natural oils that maintains the outer most layer of skin and keep the hair follicles healthy. The sweat glands produce watery secretions, which helps in the maintenance of the temperature by evaporation. The mammary glands secrete milk that help in nourishing the young ones. Hence, the correct answer is option (A).
Explanation for incorrect answer:
Option (B) reproduction, hair and skin maintenance and temperature regulation. None of the given glands are involved in the reproduction process. Hence, it is an incorrect answer.
Option (C) temperature regulation milk production and reproduction. None ofthe glands are involved in reproduction. Hence, it is an incorrect answer.
Option (D) milk production, oxygen delivery and skin maintenance. The delivery of oxygen is done by a component present in red blood cells of blood called hemoglobin. Hence, it is an incorrect answer.

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 glycerol . 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
