Chapter 34, Problem 3TY
Summary Introduction
Introduction: The reproduction is the process which results in the birth of offspring. The organisms, which show characteristics of external fertilization, often form an intermediate larval stage in between. The organisms, which show internal fertilization in their life cycle, can be oviparous, ovoviviparous, viviparous, and placental.

Students have asked these similar questions
Unchanging environments are advantageous to organismsa. that reproduce asexually.b. that undergo indirect development.c. in which fertilization occurs internally.d. that undergo pattern formation.
A.
Water currents in the ocean are much stronger than any sperm. How do sperm and egg find each other?
B.
In humans there are no water currents and the volume of the female reproductive tract is relatively limited. Then, why does the male have so many sperm?
C.
Why do sea urchins have external fertilization?
D.
Then why don't the parents take care of the young?
E.
Because the urchin life involves two or more ecological niches, they are more susceptible to predation and exposure to environmental toxins. What environmental conditions, predators and toxins might they be exposed to at each stage?
In a reptile egg, the extraembryonic membrane thatencloses the embryo in a watery environment is thea. allantois.b. amnion.c. chorion.d. yolk sac.
