What changes during a controlled experiment? A. A variable B. The results C. The conclusion D. The hypothesis

Biology
1 answer:
N76 [4]3 years ago
7 0

Answer:

Option B

Explanation:

The answer is option B or "the results." Wouldn't be option A because a variable depending on the type is tested during a experiment if you change the variable you have a whole other experiment going on, it wouldn't be option D because your hypothesis is a logically guess at the beginning of a experiment of what you think is going to happen and it doesn't change. It wouldn't be option C because the conclusion is at the end of the experiment after you finished testing, recorded the results, and found out if your hypothesis is correct meaning it doesn't change, leaving option B as your answer.

Hope this helps.

marishachu [46]

Answer:

The implications are epidemies, risk factors and disease burden.

When it comes to Typhoid, the cronic earners are treated with prescribed antibiotics, changes in sanitary habits and blood testing.

When it comes to hepatitis b, the cronic earners are treated with prescribed antivirals,  blood tests, liver ultrasound and biopsy.

Explanation:

<em>Epidemies can occur because the sick population, might not be aware and contaminate the other amount who is not infected. That is the reason why the chronic earners must take the prescribed antibiotics for as long as the physician has prescribed, they must incorporate healthy sanitary habits like washing their hands with soap after using the bathroom, not preparing or serving food to other people. Because these actions will prevent others from getting the illness. And finally, they must get tested  so that the doctor can ensure that no Salmonella Typhi bacteria remain in their body. The best way to avoid Typhoid is by vaccine.</em>

<em>Hepatitis B epidemies, risk factors and disease burden happens when the chronic earner use illegal injected drugs and share the niddle, have unprotected sex with multiple partners, receive kidney dialysis or live with someone who has hepatitis B. So the best way of managing these patients is by lifetime treatment, which means that they will take antiviral medications, interferon injections or have a liver transplant. </em>

<em>The best way of preventing the hepatitis B is by vaccine, safe sex and no drugs.</em>
