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.

Is decay of dead plant material a biotic factor or an abiotic factor?
Juliette [100K]
Technically you are able to argue both ends. Biotic factors are living things while abiotic factors are no living things. since the plant was once living, you can argue that it is a biotic factor, however, I would say the dead plant decay would be abiotic because it is not living anymore. I hope that helped!

weeeeeb [17]

The answer is it begins at the PYLORIC SPHINCTER and ends at the ILEOCECAL SPHINCTER. The pyloric sphincter is a group of smooth muscle at the joint between the pylorus of the stomach and the duodenum of the small intestine. It plays a vital role in digestion, where it acts as a valve to controls the flow of moderately digested food from the digestive to the small intestine. Ileocecal is a sphincter muscle valve that split up the small intestine and the large intestine.

Which of the following is NOT the result of a mutation in the DNA sequence of an organism?
Mama L [17]

DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.

Explanation:

Mutation is the process

It is caused by certain chemicals called mutagens or by environmental factors.

In mutation the nucleotide get change which eventually changes the protein product.

In  mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.

A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.

In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.
