Scientists claim that global climate change is threatening many species with extinction. Which statement provides the strongest evidence for this claim?A. As humans develop more land, natural habitats are lost or fragmented. B. In many species, life cycle events are adapted to occur with seasonal temperature changes. C. Species survive only in specific habitats, and cannot relocate when their environment changes. D. Species can tolerate variations in temperature, but not variations in precipitation, humidity, or other weather factors. Scientists claim that global climate change is threatening many species with extinction. Which statement provides the strongest evidence for this claim?

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
