Answer:
Theme is the central idea or insight about life
Explanation:
The answer is the second and third answers. Kingdom Protista is a polyphyletic taxon, meaning they did not evolve from one common ancestor, unlike what you see from a monophyletic taxon. Because they come from multiple ancestors, they share more similarities with other organisms from other kingdoms, rather than themselves.
Monohybrid crosses only look at one genotype. Whereas dihybrid crosses look at two genotypes.
An example of a monohybrid cross would be AA x aa, where A represents the dominant allele, and its phenotype is the colour red, and a represents the recessive allele, and its phenotype is the colour white.
An example of a dihybrid cross would be SSYY x SsYy, where the letter S represents the size, dominant phenotype is large, recessive is small, and Y represents the colour, dominant phenotype is yellow, recessive is green.
The important point is that the surface area<span> to the </span>volume ratio<span> gets smaller as the </span>cell<span> gets larger. Thus, if the </span>cell<span> grows beyond a certain </span>limit<span>, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular </span>volume<span>.</span>
