What scientific hypothesis could be used to support the theory that wood thrush decreases are not due to deforestation? could it possibly be written as an " " statement? and

"the species of bird, called a wood thrush, has declined by more than forty percent in the eastern united states since the 1980s. it was originally thought that the decrease was due to deforestation, but scientific research has provided new evidence that the decrease in this population is most prevalent in areas where acid rainfall is higher."

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.

Which of the following is caused by reproductive isolation within a species? a. a decrease in gene flow b. an increase in genetic flow c. a decrease in genetic drift d. an increase in gene flow

The more rapidly sedimentation occurs, the more likely it is that the remains will successfully form a fossil. as sedimentation continues, what happens to the amount of weight settling onto the organism? stays the same increases decreases cuts in half
