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%

student designed an experiment testing the effect of light distance on the rate of photosynthesis. she placed samples of elodea
Leno4ka [110]

The amount of oxygen produced can be quantified in order to determine the rate of photosynthesis. Elodea leaves are divided into little pieces, and the cut ends are put into the funnel's stem.

<h3>What did Elodea's bubbles in this experiment represent?</h3>

The bubbles that you observe rising from an elodea cutting's leaves are actually a result of the photosynthesis process. In some types of algae and in plants, photosynthesis takes place. In the process, light energy is changed into a sort of chemical energy that is then stored as sugar.

<h3>What substance did we use to examine whether photosynthesis existed in Elodea?</h3>

To test whether photosynthesis and/or other processes are occurring, you will conduct experiments using the dye Phenol Red in this exercise. In Elodea plants, cellular respiration is taking place. The experiments look into how light affects these processes.
