PLEASE HELP!! 5. Develop a controlled experiment testing the following hypothesis: The water temperature of the environment has an effect on a fish's breathing rate. (You will complete a-e to design the experiment.) a). Materials: List all of the equipment needed to carry on this experiment. Remember to control as many variables as possible b). Procedure: List the steps that you would follow to perform the controlled experiment. Be specific. Make sure anyone could follow your directions. c). What is the manipulated variable? (Also called the independent variable) d). What are the control(s) of the experiment? e). What is the dependent variable, (Also called the responding variable (what outcome are you looking for to measure results)

Which of these best describe conduction? a. transfer of heat between two objects that are touching b. transfer of heat by the actual movements of warmed matter c.the process in which energy is emitted by one object, transmitted through space, and absorbed by another d. the process in which energy is released by molecules

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.
