Researchers suggests that we can avoid self-confirming diagnoses by all the given options.
<h3><u>Explanation:</u></h3>
Self confirming of diagnosis of a disease is actually good for a skilled person, but for general persons, it can be very dangerous and can cause severe outcomes. Different diseases have similar symptoms, but the outcomes are very different.
Some insignificant diseases like indigestion, acidity do have symptoms of loose motion, along with severe diseases like cholera, typhoid, dysentery, and acute arsenic poisoning. So its very necessary for checking the actual cause of the disease by differential tests as well as carefully classifying the symptoms by a professional doctor.
The answer is D. This is referred to as reflex reaction. Reflex is the instantaneous and involuntary reactions to a stimuli. Reflex arc does not pass through the brain so the reaction time is shorter than normal. This is a adaptation to increase survival.
<u>Answer:</u>
The type of change that was responsible was “histone acetylation or DNA methylation”.
<u>Explanation:</u>
- Histone acetylation is the process that involves the epigenetic adjustments that functions in the transcription process while regulating DNA.
- Histone acetylation or DNA methylation is the major component of the gene regulation while passing from one generation to another.
- The Acetyl groups are hooked up to lysine’s in histone tails so their charges play a vital role to avoid the histone tail to bind with the other molecules.
The answer is C. We can suppose that the Grey gene is "A" and Black gene is "a". So the gene of heterozygous grey fruit fly is "Aa", and the black-bodied fruit fly is "aa". After mating, the offspring can get only "a" from balck-bodied fruit fly and has equal opportunity to get a "A" or "a" from heterozygous grey fruit fly. If the gene of offspring is "Aa", it will be grey. If "aa", it will be black. So the proportion of being black is 0.5.
