Answer:
proprioceptor
Explanation:
Proprioceptors are the receptor located in a joint, muscle, or tendon. These receptors are concerned with locomotion, posture, and muscle tone. These receptors respond to internal stimuli only and are present in a specific location in the body. For example, the tendon organ is a proprioceptor present in the tendon. The function of the tendon organ is to monitor the muscle tension and to prevent its tearing. These receptors also help smooth start and termination of muscle contraction.
Proprioceptors are the mechanoreceptors that regulate the body’s equilibrium and posture by their role in reflex actions that maintain muscle tone. They sense the position of limbs by detecting the degree of muscle relaxation, the stretch of tendons, and ligament movements.
I believe the answer would be D. The Moon Orbits the Earth.
Hope this helps.
Answer:
Fungi take in nutrients by C. absorbing nutrients. They suck up nutrients from decomposing matter.
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
<span>A. Stimulus is the term used to describe what causes organisms to react to their environment. Stimulus is something that can provoke organisms to respond to the world around them. For example, if you put your hand on the stove, the stove is going to be the stimulus for you to get burned and move your hand from it because it will be to hot - that is going to be your reaction to the stimulus. Camouflage is a type of hiding mechanism, parasites are organisms, and homeostasis is equilibrium in an organism. </span>
