WILL GIVE BRAINLIEST!!!!What are the similarities and differences in the way geologists and biologists approximate the age of th

e earth? Justify your response in two or more complete sentences.
Biology
1 answer:
____ [38]3 years ago
4 0

Answer:

Geologists can determine the age of an rock by studying it. However biologists study the evolution of fossils.

Explanation:

Geologists can determine the age of the Earth by studying the rocks and how long it took / takes them to form. Some similarities in their way of studying the Earth are the study of fossils. Both geologists and biologists study the evolution of fossils.

further information:

Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. ... Geologists conduct studies that locate rocks that contain important metals, plan the mines that produce them and the methods used to remove the metals from the rocks.

Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies--human medical research, plant research, animal research, environmental system research--at the cellular level or the ecosystem level or anywhere in between. ... Biologists generally love what they do.

in conclusion, geologists are able to tell a rocks age by studying it but biologists can only study the age of fossils

hope this helped!

In colorectal cancer, some tumor suppressor genes are inactive. This is an important factor resulting in uncontrolled cell divis
tresset_1 [31]

Answer/Explanation:

(1) a mutation in the coding region, resulting in an inactive protein

To check to see if there is a mutation, you could extract the DNA from the cancer cells and then perform PCR to amplify the gene of interest. You could then perform sanger sequencing and compare the sequence to the normal gene to see if a mutation is present. To test the effect of the mutation, you would want to see if an active protein has been formed.

To see if a normal sized protein has been formed, you could perform a western blot, comparing the protein band to the WT protein band. If the protein is absent or much smaller, it is likely not a functional protein.

(2) epigenetic silencing at the promoter of the gene, resulting in reduced transcription.

To check for changes in the epigenetic landscape of the promoter, you could perform chromatin immunoprecipitation by extracting the chromatin from the tumour cells and using antibodies for different chromatin marks to see what has changed between the normal cells and the tumor cells. E.g. H3K9me3, H3K27me3. You would perform a pull down with the antibody of interest and then PCR for your promoter to specifically look at changes at that gene compared to normal cells. To test DNA methylation, you could perform bisulfite sequencing.

To see how transcription is affected, you could extract RNA from the tumor and normal cells, and compare the levels of RNA between the two samples by qRT-PCR
