Name four factors that affect population growth then explain how each factor contributes to population growth
daser333 [38]

Answer:

Contraceptive Education/Availability, Healthcare, Country Development, and Political Climate

Explanation:

When people are educated about proper contraceptive use they can still have sex without the consequence of pregnancy. The availability of contraceptives goes hand in hand with contraceptive education.

Advanced healthcare can help prevent disease through immunizations and further the life expectancy of the country's population. Hand washing can significantly lower the spread of disease.

The lower the development of a country the higher the birth rate is, while the higher the developed countries have a lower birth rate and their life expectancy is much longer.

The political climate of a country can greatly affect the population growth. The more negative the political climate is usually causes a smaller birth rate. For example when China implemented the one child policy their population growth declined;.

Before a captive breeding program and subsequent reintroduction of the black-footed ferret it is believed that their total popul
irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%
