Answer:
A
Explanation:
Here, we want to pick which of the options is a correct answer to being the benefit of naturally occurring forest fires.
The correct answer is that they help to spread the seeds of some trees.
Naturally occurring forest fires ravages the forest and thus work with wind force. They proceed through the entirety of the forest from the point in which they start.
By moving from a particular point in the forest to another point in the forest, they allow for the process of mass movement to naturally occur.
By translocation from one point to another, they take the seeds alongside with them and thus allows for the dispersal of these seeds through the forest
The similarities between bones of humans and other animals shows that every living creature on earth has a common ancestor, even if that common ancestor is as simple as a sing-celled organism.
Answer:
some kinetic energy to electric energy are good. for a hand cranked flash light it takes a lot of physical energy to get the light on for a large amount of time. LEDs are used because they are bright with even a little energy. solar/light energy is very useful aswell
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:
Not sure what answer it is But it seems to be herbivore
Explanation:
a plant/animal eating and digesting food is?
Digestion starts with the teeth. Herbivores have large, flat teeth that grind up plant materials. ... Once the plant materials are chewed, special bacteria in the gut of an herbivore and the longer digestive tract break down the plant material. Ruminants regurgitate food and rechew it to help with the digestive process.
