7 0

Answer:

4. Brown

5. Brown

6. Blue

7. Long

8. Long

9. Short

Explanation:

Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.

Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.

Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.

For recessive long tails, tt gives short tails, TT and Tt gibe long tails

kotegsom [21]

Answer: Option B and C.

Heavy and continuous rains flood the land, submerging habitats.

c. Lightning strikes a tree and begins a fire that clears the land.

Explanation:

Heavy and continuous rains flood the land, submerging habitats.

Lightning strikes a tree and begins a fire that clears the land.

The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.

Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.

Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.

Therefore, Heavy and continuous rains flood the land, submerging habitats.

cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
