Answer:
Driving a car, smoking, burning of woods for heating purpose and cooking food.
Explanation:
Driving a car, smoking, burning of woods for heating purpose and cooking food are the activities that are performed in our home daily. These activities greatly affected the biogeochemical and hydrologic cycles by increasing the concentration of carbondioxide gas in the atmosphere. 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.
Answer:
Random distribution.
Explanation:
The distribution of the population in space across an area is largely driven by the food and other resources in the environment. Uniform, random and clumped are the main distribution pattern.
The grass is distributed randomly in the environment, the population of deer is most likely to have random distribution pattern. Since, the distribution pattern depends upon the food resources so the deer have random distribution in space.
Thus, the correct answer is option (D).
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.
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!
