Answer:
Most fossils are found in sedimentary rocks, those rocks produced by the accumulation of sediment such as sand or mud. Wind and other weathering conditions wash away sediment on land, depositing it in bodies of water. For this reason, fossils of sea creatures are more common than those of land creatures.
Explanation:
Answer:
equilibrium
Thats the answer to the question
Vertebrates:
1) They've got a backbone/spine.
2) Are probably more complex organisms: fish, amphibians, reptiles, birds, mammals (in that order.)
3) Movement is based on an internal skeleton.
4) Wide range of sizes and shapes.
5) K-selected population
Invertebrates:
1) No backbone.
2) Less complex: sponges, worms, mollusks (e.g. snails) , crustaceans (e.i. crabs.) Insects.
3) Movement is not based on an internal skeleton, or some don't move at all.
4) Must be small in size to fulfill their needs for air and nutrients because systems are simpler.
5) R-selected population
Answer:
Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object.
Explanation:
DNA stands for deoxyribonucleic acid. RNA stands for ribonucleic acid. Both RNA and DNA contain Adenine, Cytosine, and Guanine. However, DNA's nitrogenous base is Thymine while RNA's nitrogenous base is Uracil.
