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

all answers true and false

explanation:

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
