Answer:

Emerging infectious disease is the one which has recently started to spread in human population. Either its cases are going up or its geographic range is expanding. Ex: HIV AIDS and H1N1 virus. Reemerging infectious disease is the one which had declined substantially in the past but now is emerging again. It survived in the past and adapted to the new environment to reemerge. Ex. Dengue and West Nile virus

Since 1970s around 40 infectious diseases have been discovered. There are many reasons for the spread of infectious diseases. As humans are able to travel anywhere they are getting exposed to foreign environment a lot. Population is also increasing which has lead to people living very close to each other. Contact with animals has also increased leading to exposure to various new pathogens.

Burning of fossil fuels in the car engine and burning of woods releases carbondioxide gas that causes air pollution. The use of electric cars and electric heater can decrease the impact on these biogeochemical and hydrologic cycles.

Harrizon [31]

It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.

The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.

rusak2 [61]

Your answer would be D, Systemic circulation carries oxygenated blood to the body and pulmonary circulation carries deoxygenated blood to the lungs.

These two circulations are part of the circulatory system, with the pulmonary circulation taking deoxygenated blood to the lungs and returning it oxygenated with the oxygen we breathe in, then that oxygenated blood going around the body delivering that oxygen and coming back deoxygenated.

Hope this helped!
