Base your answers to questions 24 and 25 on the
information below and on your knowledge of
biology.
A biologist found some frog eggs in the water of
a pond. Most eggs contained a developing
embryo. A large fish was observed feeding on
these eggs.
24. What type of fertilization and development
was involved in the production of the
embryos?
(1) external fertilization and external
27. In an organism, a muscle cell has the same
DNA as a nerve cell, yet the cells perform
different functions. This is possible because
(1) different mutations occur in each cell
type, changing the genetic instructions
(2) temperature variations within the body
alter DNA
(3) proteins in each cell type change the
structure of DNA
(4) different parts of the genetic instructions
are used in each type of cell
development

listed below.

development

some eggs survive and develop. The best
explanation for this is that
(1) the fish are poisoned as a result of eating
the
eggs

asexually
