I have made a thermometer which measures temperature by the compressing and expanding of gas in a piston. i have measured that at 1000 c the volume of the piston is 20 l. what is the temperature outside if the piston has a volume of 15 l? what would be appropriate clothing for the weather?

Tortoise shells and snail shells are similar in function: they protect the organism from predators. based on a comparison of the organisms in the images, what can you conclude? 1. tortoises and snails have homologous organs, and they’re evolutionarily related. 2. tortoises and snails have homologous organs, and they belong to same species. 3. tortoises and snails have analogous organs, and they belong to the same species. 4. tortoises and snails have analogous organs, and they don’t belong to the same species. 5. tortoises and snails have analogous organs, and they aren’t evolutionarily related.
