Chapter 10, Problem 2RQ
Summary Introduction
Introduction:
Reproduction is one of the basic functions among all living organisms. The process varies from simple cellular division in case of unicellular bacteria to the very complex process of development of organs in higher animals. Development of the lungs takes a special place in the development of the fetus. Development of the lungs takes place in five phases. They are:
Embryonic phase
Pseudoglandular phase
Canalicular phase
Terminal saccular phase
Alveolar phase

Which of the following statements about hydration is true?
Absence of thirst is a reliable indication that an individual is adequately hydrated.
All of these statements are true.
Although a popular way to monitor hydration status, weighing yourself before and after intensive physical activity is not a reliable method to monitor hydration.
Urine that is the color of apple juice indicates dehydration.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results:
