Answer: Because it can change size based on the needs.
Explanation:
<u>The term niche defines an organism´s role in an ecosystem </u>and it also encompass what the organism eat or how it interacts with nonliving elements of the environent.
The realized niche could be regarded as flexible because it is able to change its size based on what it needs. For example, it could increases or decreases its size in competition between resources with other species since they are part of the same ecosystem.
 
        
             
        
        
        
Answer:
Sea ice has a greater impact on sea level rise than land ice. Sea ice is much more variable in volume and mass than land ice, which is relatively fixed. As a result, sea ice has a greater impact on sea level rise.

Answer:
50% probability of Pp (purple) or pp (white) genotype.
Explanation:
P = purple gene
p = white gene
Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Punnet Square:
![\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26P%26p%5C%5Cp%26Pp%26pp%5C%5Cp%26Pp%26pp%5Cend%7Barray%7D%5Cright%5D)
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white;
Or, there is a 50% chance of having either genotype, of being purple or white.
