In 1994, naturalists in Australia discovered a new genus and species of conifer, Wollemia nobilis, growing in a remote area not far from the city of Sydney. This was the first new conifer discovered since 1948. Wollemi pine (not really a pine) is in a family that had global distribution in the Crustaceous period. Scientists used a variety of different evidence to decide where this rare tree should be placed in the "Tree of Life." What evidence would be necessary to determine that this is in the phylum Coniferophyta?

Darrel conducted an experiment with the following procedure: fill two cups with ice water. place an uninflated balloon snuggly onto your left index finger. blow a little air into an identical balloon, and place it onto your right index finger. place both fingers into the cups of ice water. darrel noticed that his right finger felt warmer in the ice water than did his left finger. which of the following does the experiment show? a. air is a good radiator of heat. b. air is a good insulator of heat. c. air is a good conductor of heat. d. air is a good convector of heat.
