what is the sensitivity of freshwater wetland? I have to give three pieces of evidence and explain why it is sensitive or why no
zlopas [31]
When it comes to freshwater wetlands, hydrology plays a large role in nutrient stoichiometry and sensitivity to nutrient inputs. Although wetland biogeochemists intuitively understand these important relationships between landscape position, hydrology, and sensitivity to nutrient inputs, these relationships have never been quantified using geospatial data. The objective of this project will be to evaluate and quantify the linkages between watershed catchment characteristics and freshwater wetland nutrient sensitivity ur welcome

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%

A frog with a mass of 0.29kg hops up in the air. At the highest point in the hop, the frog has a gravitational potential energy
PtichkaEL [24]

Answer:

0.27m

Explanation:

To get the energy

Potential energy= Mgh

M is Mass

G is acceleration due to gravity

H is height..

M= 0.29kg, h= ?

P=0.759. g=9.8m/s

Therefore,

0.759=0.29×9.8×h

H= 0.759÷2.842

H= 0.27m
