When hurricane swept an inland, many organisms of the ecosystem will get eliminated from that territory.
This provides the perfect ground for conducting natural laboratories because now he could observe the restarting ecosystem at its earliest forms.
The true statements about the situation are:

-Natural selection can lead to rapid changes. The average leg length of lizard populations decreased within a few generations.
-Islands scrubbed by hurricanes allow researchers to introduce new lizard populations and observe their evolution.
-There are many small islands with similar environments, meaning that researchers can repeat their experiments and observations in several locations

Hello. This question is incomplete. The full question is:

""Jonathan Losos and colleagues conducted experiments on small, hurricane-swept islands as "natural laboratories." Which of the following statements is true?

Natural selection can lead to rapid changes. The average leg length of lizard populations decreased within a few generations. - Islands scrubbed by hurricanes allow researchers to introduce new lizard populations and observe their evolution. - The legs of the anoles placed on the islands became shorter, and their offspring inherited shorter legs. - There are many small islands with similar environments, meaning that researchers can repeat their experiments and observations in several locations. - Experiments on the small islands show evidence for adaptation by natural selection but not for evolution."

Natural selection can lead to rapid changes. The average leg length of lizard populations decreased within a few generations. Islands scrubbed by hurricanes allow researchers to introduce new lizard populations and observe their evolution. There are many small islands with similar environments, meaning that researchers can repeat their experiments and observations in several locations.

Explanation:

Hurricane is a tropical storm (or cyclone) that corresponds to a low pressure system, that is, the pressure in this region is less than that of the areas around it. These areas are unstable and associated with cloud formation, humidity and strong winds.

Hurricanes are meteorological phenomena that can cause enormous destruction wherever they go. After an area is hit by a hurricane, it may go through a process of adaptation and natural selection of many species.

In the case of the question above, in the analysis of Jonathan and his colleagues, they can find the following observations:

What was dr. willem johan kolff’s first step in using the scientific process to invent the hemodialysis machine? he built the machine and tried it with various patients, collecting data about its effectiveness. when a patient’s kidneys failed, he wondered if it would be possible to perform kidney functions with an external machine. he researched and collected data about numerous patients who exhibited symptoms of kidney failure. he drew conclusions from studies of various symptoms of kidney failure, and drew a design for the ideal external blood-processing machine.

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.
