Apopulation’s emigration in one month totaled three individuals. during the same period, immigration was 17 individuals. birth rate was 12, and mortality was 26 due to a parasite infection. what was the net effect on the population?
a) -14
b) 0
c) +12
d) +26

b) 0

Explanation:

Given that:

Emigration = 3, Immigration = 17, Birth = 12, and Mortality = 26

Net effect on the population, which is the change in population, can be calculated using the formula (Births + Immigration) - (Mortality + Emigration)

Therefore, Net effect = (12 + 17) - (26 + 3)

                                   = 29 – 29

                                   = 0

The net effect on the population is 0. There is no increase or decrease in the total population

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
