Conditioned stimulus
Classical conditioning is a learning procedure in which a biologically potent stimulus paired with previously neutral stimulus. This pairing will cause a response that can be the same as the potent stimulus. This is done repeatedly for an organism to elicit a conditioned response to the previously neutral stimulus that was paired to the active stimulus. The dog salivates due to the idea that food is related to the sound of the bell.
Planet earth is the only known region of the universe to host life and so the basic criteria for life is based on observations made here. For an entity to be considered a living organism it must contain DNA or some other means of storing genetic information. The second criteria is that it must have some way of extracting nutrients from its surroundings. The organism must be able to respond to environmental stimulus and last but not least it must be able to reproduce.
Balamuthia mandrillaris is an amoeba that was discovered in 1986 in the brain of the baboon that dies in San Diego Wild Animal Park. This can be found in the soil and water, therefore it is freely living. It is known to cause the neurological condition known as granulomatous amoebic encephalitis. In a study published by National Center for Biotechnology Information, it has a case fatality rate of >98%. Majority of this case can be found in warmer regions that affects individuals mostly of Hispanic origin. Documented cases had been reported from the Latin Americas in significant number, followed by the United States, Asian regions and some in Europe. However, a specific number of cases worldwide may never be known due to the following factors: lack of awareness, poor diagnosis and a poor public health system.
It is still yet to be known if its a serious public health concern worldwide.
Answer: as the predator’s population goes up, the preys will go down, and as the prey’s goes up, the predators will go up. They are basically the opposite of each other.
Explanation: I can’t really tell what your question is. However if there are more prey to eat, then the number of predators will grow because they have more food. However, once there’s too many predators, the number of prey will drop which lowers the amount of food.
