Cell is the structural and functional unit of life. All living organisms are made up of cells. The size of any living cell is limited. Limited cell size has many advantages.
Answer: Analogy to explain why cell size is limited is SMALLER THE SIZE OF A CELL LARGER WILL BE THE SURFACE AREA TO VOLUME RATIO.
I think that those are the results of the cross

Answer: the functions of the skeleton. Structure, protection (ribs), allow movement, chemical/physiological: stores calcium and the tissues are made up of the same material
Explanation:
Answer: The genotype for the parent organism whose genotype is unknown is Ff.
Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.
The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).
A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).
Ff x ff = Ff, Ff, ff and ff.
Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.

For a monohybrid cross, you are crossing two alleles with two alleles. in a dihybrid cross, you are crossing four alleles with four alleles.
