Answer: The correct answer is- D) Sweat.

Non specific defense is a type of immune response ( also called innate immune response) that does not target any specific disease causing organism ( pathogen such as any specific bacteria or virus).

It is mainly provided by the surface of body ( such as skin that acts as an important barrier against external agents).

Sweat is an example of non specific chemical defense as it makes the surface of skin ( epithelium) acidic, thereby inhibiting the growth of pathogens ( such as bacteria) on it.

Thus, option D) is the right answer.

Nitrates are made by converting ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). What do you predict the O2 levels in
AlexFokin [52]

Answer:

Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low

Explanation:

Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.

What causes ocean water near the equator to be warmer than ocean water<br> farther north?
ASHA 777 [7]

Answer: The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as the sun's rays hit them directly. :)
