Answer:
the answer is D ecosystem
Because of a tide probably or rain
A) This is predator-prey relationship.
B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.
- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.
C) Let population A be Zebras, and population B Lions.
From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.
Answer/ explanation :
Reflex response is an involuntary, automatic and rapid response to a stimulus.
It's is controlled by the brain stem.
Reflex actions cannot be controlled. They are coordinated by nerves which moves to and fro in the spinal cord without a direct involvement of the brain.
Examples of a reflex response
Sneezing, coughing, yawning, toughing a hot object, blinking of the eyes.
There are two types of reflex response
Autonomic reflex arc
The somatic reflex arc
The reflex responses happens so quickly because they do not have to be processed by the brain before taking place.
Well, you failed to mention which one is the recessive trait in this instance. But, let’s say red hair is recessive, denoted by r and brown hair is dominant denoted by R. Mom is rr and dad is RR. All children are going to be Rr and so heterozygous. They will all carry the trait for red hair but will express brown hair themselves, so 0% probability of having a child with red hair from the initial parents
