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%
Answer:
50% tongue and 50% no tongue.
Explanation:
Upper case T is dominant over lower case t recessive, so we can see that there are two Tt and two tt.
you have to make the Table like this.
T t
t Tt tt
t Tt tt
Final answer 50% tongue and 50% no tongue.
The mistake is fixed.
Answer:
Soil pollution- Soil pollution is defined as the presence of toxic chemicals in soil
it could pose a threat to humans, etc...
caused by the presence of xenobiotic chemicals
(A xenobiotic is a chemical substance found within an organism that is not naturally produced or expected to be present within the organism.)
or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.
Air pollution- Air pollution is a mixture of solid particles and gases in the air.
Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.
Explanation:
The new species come from old ancestors of the animals that were there, over time they slowly evolved, and they adapted to that new environment.
I believe that both flatworms and roundworms have a body type called Bilateral symmetry. Animals that are bilaterally symmetric have mirror symmetry in the sagittal plane, which divides the body vertically into left and right halves, with one of each sense organ and limb pair on either side.
