You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

What would be the finite rate of increase for a population that has leveled off at its carrying capacity(K)? (Hint: if we assume carrying capacity is 149 and the population is at carrying capacity from T9-T12, calculate the finite rate of increase).

Answers

For a  finite rate of increase for a population that has leveled off at its carrying capacity the finite rate of increase will be zero (zero), Because all of the available resources have been used.

What is Population?

Generally, a population is the total number of people who live in the same area. The population of a city is the number of people who live there.

In conclusion, After population has reached its carrying capacity, the finite rate of increase will be zero (zero). Because all of the available resources have been used, the ecosystem will not allow for growth.

The Fallele generates long fur and the f allele generates short fur. Because only one F copy is needed to show the trait, if a guinea pig has the FF or Ff allele combination, they will have long fur. If they have the ff allele combination, they will have short fur. There is a total of 7 8 alleles in this population, There are 5 Falleles in the population. There are 3 ✓ falleles in the population.
