All of the following statements regarding fossils are true except: a. a trace fossil is a fossil created from the remnants of a dead organism. c. a mold fossil is an imprint of the organism on the rock. b. amber-preserved fossils are the most common form of fossils and are actually the least in studying organisms. d. petrification is the result of a dead organism hardening and turning to stone or rock, as seen in petrified trees

Option C

Explanation:

Amber- preserved fossil are not the most common form of fossil and if found are very helpful for study purpose.

The amber fossil can be defined as the the fossil in which the organism is trapped in the fluid that oozes out from the trees.

The organism gets trapped inside it and remains perfectly preserved and this is known as amber.

This is good for studying purpose as the organism remains intacked  in it.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

because the light is a great source of energy for the plants to survive. (i hope this )
