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.
The correct answer is centrosome.
<span>The centrosome is the main microtubule organizing centre of the animal cell and it is involved in the regulation of cell-cycle progression. During the mitosis, the centrosome microtubules can interact with the chromosomes to build the mitotic spindle.</span>
It seems that you did not provide possible answers, but the mark recapture method is one method that is not very invasive. The population size is estimated by marking a certain number of individuals and releasing them into the wild, followed by a second capture later on. The members captured the second time with the markets from the original capture are used to estimate population size in the formula s*n/x where s and n are the first and second captured population sizes and x is the number of marked inidividuals from the second capture.
