Question
Chapter 38, Problem 1CT
Summary Introduction
To describe:
The way in which an embryo obtains the oxygen for aerobic respiration because at no point in human development does embryo has functional gills.
Introduction:
Fertilization is the process in which male and female gametes are fused to make an embryo. This embryo later develops into an organism. It undergoes several developmental processes to form a complete organism.
