Fossil records can be studied to determine how organisms change over time. which of the following methods for studying organisms could least likely be accomplished by studying the fossil record?

Comparing sleep patterns of organisms

Explanation:

Fossils can be described as the imprints of the dead plants and animals which once were present on the Earth. Fossil records have helped the scientists to learn the history of the Earth and the organisms which once constituted the earth. Fossil records have helped us to understand the evolutionary relationships that might be present among members of different species.

However, by fossil remains, we cannot determine the sleeping patterns of an organism.  

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
