<span>Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them. Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.  </span>

Answer:

fossil record, history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock.

Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind.

What can be inferred about a petrified log? the wood needed long ages before it could petrify the tree laid on the surface for l
RideAnS [48]

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.

How can microalgae be used to create biodiesel
mestny [16]

The oil extracted through these methods is referred to as "green crude" and it's not ready to be used as fuel until it undergoes another process called transesterification. This step adds more substances to the mix, including alcohol and a chemical catalyst that causes the alcohol to react with the oil. This reaction creates a mix of biodiesel and glycerol. The final step in processing separates the glycerol from the mixture and leaves a biodiesel that's ready to be used as fuel. Maybe one day it really will be easy being green.
