Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
Answer:
An unconditioned response.
Explanation:
Pavlov was the process of studying salivation in dogs as a part of a research program on chewing and digestion. This is known as a normal reflex that is under personal choice or control and also called an unlearned evolutionary response.
In terms of Pavlov's analysis of learning, Pavlov built a device that would help to accurately measure the amount of saliva produced by dogs. In the case of Pavlov dogs, the food is called as the stimulus and salivation is called as a response.
Answer:
The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.
Explanation:
The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry anywhere.
Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.
Thus, the worst option are- nuclear, hydroelectric, combustion and fuel burning energy source.
