Consider the following data. rates for cheetah population from 2011 to 2012 cause of change 2011 2012 deaths 2 1 births 5 4 immigration 6 1 emigration 8 3 which would have to happen to make the population growth of cheetahs in 2013 equal to the population growth observed in 2011 and 2012? a) 4 deaths, 7 births, 2 immigration, 6 emigration b) 3 deaths, 6 births, 5 immigration, 7 emigration c) 5 deaths, 2 births, 8 immigration, 3 emigration d) 1 deaths, 5 births, 3 immigration, 7 emigration

The correct answer would be B) 3 deaths, 6 births, 5 immigration, 7 emigration.

Population density of an area in a specified time can be calculated with the help of formula N = (B + I) – (D + E), where,

Thus, the population density in 2011 would be = (5 + 6) - (2 + 8) = 1.

Similarly, in 2012 the population density would be = (4 + 1) - (1 + 3) = 1.

Population density according to data provided in option B = (6 + 5) - (3 + 7) = 1.

Thus, correct answer would be option B

b on edge

Explanation:

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
