Answer:
the petrified log looks like the original tree.
Explanation:
A tree to be petrified first needs to be buried. An element laying on the surface can not be petrified because it is exposed to many different factors (such as<em> organisms, microorganisms, climatic conditions</em>, etc.), that affect the petrification process. So, in the case of a fallen tree, first, it needs to be covered by many sedimentary layers. Once it is underground, it also needs the presence of underground water and minerals. Water replaces the original organic material with minerals (silica, calcite, and pyrite). This replacement process results in the conversion of the woody material into a fossil of the original material. Very often, the tree details are so preserved that the fossil looks exactly like the original trunk.
Depending on the preservation degree, a fossil can be useful for different studies about the past.
-Surface area to volume ratio. (surface area / volume)
-Nucleo-cytoplasmic ratio.
-Fragility of cell membrane.
-Mechanical structures necessary to hold the cell together (and the contents of the cell in place)
Answer:
Coal and oil (if there are two answers)
Even though the wind tries to flow from high pressure to low pressure, the turning of the Earth causes the air flow to turn to the right so the jet stream flows around the air masses, rather than directly from one to the other.hope this helped I just learned this two weeks ago
Answer:
A
Explanation:
Blow flow in the capillaries is slowest despite the large surface area. This is to allow for exchange of gases and nutrients at the cellular level.
