g The authors designed a field experiment to test the hypothesis that competitive interactions between the closely related A. segrei (an introduced species) and A. carolinensis (a native species) would cause a change in the perch height of A. carolinensis. What aspects of the experimental design were used to help rule out potentially confounding variables? Select all that apply.

Explain the cellular functions that occur when antibiotics attack a bacteria cell. a. antibiotics target the cell wall, cell membrane, and the processes of protein and nucleic acids production in bacteria to rupture the cell. b. antibiotics create dormant resistant endospores to preserve the genetic material and rupture the cell. c. antibiotics target the cell wall and form a bridge-like connection to form conjugation. d. antibiotics use binary fission to grow twice its size, replications its dna, and split into two cells.
