I think what is indicated when, in spite of being injected with a pathogen isolated from a sick animal, another animal remains healthy; is that the animal could be immune to that particular pathogen or may be the pathogen was not pathogenic. A pathogen is an agent that causes a disease;;according to Koch postulates when isolated pathogen is injected into a healthy animal, animals must develop disease, which if the disease is not developed, then the pathogen is not pathogenic or may be the animal is immune.

What effect do ocean currents have on weather and climate on Earth?
Yuri [45]
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Study the photosynthesis model above. What is a correct assumption about the inputs and outputs of photosynthesis.
Archy [21]

Although I see no photosynthesis model, I can assume that the correct answer is that the inputs for photosynthesis are the outputs for respiration, and the outputs for photosynthesis are the inputs for cellular respiration. Therefore, they both depend on each other to keep themselves going.
