Environment, genetics, selective breeding, random mating, random fertilization, recombination, crossing over, etc
One explanation could be the differences in climate (environmental factors). The climate in northern Mexico could support the reproduction of the mosquito species, which is a vector of the dengue virus. Other environmental conditions that influence its endemicity could include living conditions and sanitation. The other possiblity could be that the people in the US have developed immunity for the disease, therefore, are unaffected even when infected by the virus.
Well, if you look at the scientific process, the first step is to have a question to base it on.
Answer:
Exponential Growth: y = a(1 + r)x
Exponential Decay: y = a(1 - r)x
Explanation:
Remember that the original exponential formula was y = abx.
You will notice that in these new growth and decay functions,
the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).
The growth "rate" (r) is determined as b = 1 + r.
The decay "rate" (r) is determined as b = 1 - r
Answer:
1

Cell division involves splitting the parent cell into two identical daughter cells
