Chapter 31.4, Problem 1SB
Summary Introduction
To review:
The type of body symmetry present in sponges.
Introduction:
The sponges belong to phylum Porifera. The major characteristics of the sponges are the lack of true tissues, not able to form complex layers, and even their structures are not fixed. During the maturation of sponge, they become less sessile and it makes them to change their structures. They are mostly found in the shallow coastal areas and are present in plethora since Cambrian.

A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
