B. pressurized liquids

A hydraulic system utilizes a compact liquid as its fluid, rather than compressible fumes. In this type of device, hydraulic fluid is communicated completely through the machine to several pressure-driven motors and hydraulic automobiles and becomes pressurized according to the resistance present.

Power steering liquid is the type of hydraulic liquid. Most are crystal oil or silicone dependent fluids, while some use automated transmission fluid, made from artificial base oil.

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

Answer:

In natural environments, horses typically live in relatively stable social units. Horses live in herds so that they are able to fulfil their basic needs, which are to avoid danger or harm, and to reproduce successfully and bring up healthy foals.
