With whom do you agree most? Explain why you agree with that friend.
Phantasy [73]

Answer:

I agree most with Natalie. Particles in a gas are very high energy/move around a lot, and well separated. Meanwhile, liquids particles don't move as much as the gas particles do,  but still have considerable movement and are closer together. Finally, solids are composed of particles that are tightly packed together and move the least out of the three states.

Hope this helps!

Does the high concentration of the morrison formation mean that more organisms lived here 150 mya compared to other other parts
Scilla [17]

Answer:

Jurassic Fact: The Morrison Formation is named after the town of Morrison, Colorado.

Explanation:

The Morrison Formation is a rock unit from the Late Jurassic (155 million years ago-148 million years ago). It extends throughout the Western United States and often contains fossils of dinosaurs such as Camarasaurus, Diplodocus, Apatosaurus, Stegosaurus, Allosaurus, and others. Although the Morrison was deposited in a wide variety of environments, it is the river channels that are most likely to contain dinosaur bones. Quiet water lake and pond deposits are best for preservation of the small delicate skeletons of salamanders, frogs, lizards, and others. In order for a fossil to form, the body must be buried quickly before weather conditions and scavengers have a chance to scatter or otherwise destroy the bone. In the park you will also see "Rainbow Beds" of the Morrison, which are mostly crumbly grey and maroon mudstones. They are pretty to look at, but do not often contain dinosaur fossils.

Most chemical digestion and absorption of nutrients takes place in the _____.
lesya692 [45]
Most chemical digestion and absorption of nutrients takes place in the _small intestine_.
All macronutrient (protein, carbohydrate, fat) breakdown into their basic subunits (monomers) is finalized in the small intestine. This is where all foodstuffs will meet the last set of enzymes and emolients/emulsifiers (dissolvers) to do the final breaking of bonds (chemical digestion). And it is therefore also in the small intestine that a vast blood supply allows a special circulatory route to absorb (pick up) these nutrients (sugars, amino acids, small fatty acids) via their tiny capillaries, and transport them to the liver for processing. This circuit is known as the Portal Venous System.
