Taxonomy is the science of naming and classifying organisms based on structural comparisons and genetic evidence.
Taxonomy is the science of finding, describing, classifying and naming biological organisms (plants, animals and microorganisms) based on shared characteristics and genetic evidence. Organisms are arranged into taxonomic ranks, and groups of a certain rank can be combined to form a higher rank, thereby forming taxonomic hierarchy. The main ranks that are used in taxonomy currently are domain, kingdom, phylum, class, order, family, genus and species.
The correct answer is D. Sunning themselves
Sunning or sunbathing is a method used by the organism to raise its body temperature.
The options changes in blood flow, panting, and sweating are means of the endotherms to cool their body temperature.
The definition of an ecological relationship is the relationship between organisms in an ecosystem, so you can find them in almost any ecosystem.
I think the correct answer would be the first option. The best method to use in order to measure the distance of star would be to calculate the variations in the position of the star due to movement of Earth in its orbit. The doppler shift which is what is being described in the last three options does not calculate the distance rather it calculates the relative velocity. The method used in measuring the distance was introduced by Edwin Hubble where he found that relative velocity of a body in space is directly proportional to the distance of that body from Earth.
