Dmitry_Shevchenko [17]

Answer:

α = 0 if β= 0

Explanation:

If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.

choli [55]

The right answer is glutamate

Glutamate is a major excitatory neurotransmitter associated with learning and memory.

It is also associated with Alzheimer's disease whose first symptoms are felt in memory.

Most people unknowingly consume monosodium glutamate (MSG), a commonly used food additive.

An experiment was done on healthy patients, giving them 12 grams of glutamate. It was found that the experience led to headaches, nausea or jaw pain in 50-60% of cases.

It was also measured the level of glutamate contained in the muscles of patients with jaw problems. The tests concluded that the most painful muscles were those containing the highest levels of glutamate.

According to him, one of the keys to chronic pain could lie in the development of drugs that reduce the rate of glutamate.

Producers are organisms that make their own food. Plants would be an example. Primary consumers would be those that eat producers(plants,algae). Secondary consumers are animals that eat primary consumers. Herbivores are animals that only eat plants. Carnivores are those that only eat meat and don’t eat plants. Omnivores are those that eat both meat and plants. De composers are those that decompose organic material like dead animals. The herbivores here are the kangaroo rats,grasshoppers and bunny’s. The carnivores here are the hawk,lizard,tarantula and rattlesnake. I don’t think there is an omnivore. And the only decomposed here is the bacteria. As it decomposes the bodies of the animals when they are dead.
