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.

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB.
