Answer:
9 per 1,000/yr.
Explanation:
The population growth rate is 9 per 1,000/yr.
The rate of growth of population is determined by the following formula:
<em>Growth rate = B - D + I - E</em>
<em>Where B = birth rate, D = death rate, I = immigration, and E = emigration</em>
In this case, B = 26, D = 15, I = 7, and E = 9. Substitute these values into the equation of growth rate.
Growth rate = (26 - 15) + (7 - 9)
= 11 - 2 = 9
<u>Hence, the growth rate of the deer's population is 9 per 1,000/yr.</u>
The answer is; B
Mutation is one source of variation (in addition to sex and gene flow). Mutations are rare and occur in a small proportion of individuals. However, due to the advantage that the genetic mutation confers to these individuals, their chances of passing the genes to the next generation is higher than that of the general population.
This way, the allelic frequencies of these advantageous mutated genes increase with each generation and eventually become the majority population over time.
When distance increases gravity decreases. Distance decreases then gravity increases. Directly proportional.
