Answer:
Niche
Explanation:
Niche basically is the lifelihood of a species that involves feeding on what, drinking from what.... 
If both species are competing for the same resources, they would compete until a certain species is eradicated. (think of it as 2 species of ants in 2 colonies that are close to each other, take the same leaves, prey and stuff. They would fight with each other in other until one colony is eradicated.) hence, unless a species and adapt and change its niche, both species would fight until one is eliminated. Thus, the principle states that 2 species cannot continue to occupy the same niche, not living environment.

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory. 
<h3>Synthetic theory of Evolution </h3>
- The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.
The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment. 
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance. 
Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

Answer:
Like healthy cells, cancer cells cannot live without oxygen and nutrients. So they send out signals, called androgenic factors, that encourage new blood vessels to grow into the tumor. This is called parthenogenesis. Without a blood supply, a tumor can't grow much bigger than a pin head.
