Given the conditions referenced in the question, which include independent assortment and simple dominance, crossing these two parent genotypes will yield an expected 75% of the offspring resembling the AABBCc genotype parent. To elaborate, independent assortment is when an organism's alleles for a trait separate independently during meiosis, while simple dominance refers to the effect of dominant and recessive alleles for a trait—with the trait appearing if at least one dominant allele is present. Understanding these principles allows us to solve the problem. For Parent 1, the genotype is AABBCc, and the possible allele combinations produced are ABC and ABc. For Parent 2, with a genotype of AabbCc, the assortments include AbC, Abc, abC, and abc. After using a Punnett square to combine these alleles, the resulting genotypes are AABbCC, AABbCc, AaBbCC, AaBbCc, AABbCc, AABbcc, AaBbCc, and AaBbcc, leading to a genotypic ratio of 1AABbCC: 2AABbCc: 1AABbcc: 1AaBbCC: 2AaBbCc: 1AaBbcc. The phenotypic ratio expected from this cross is 6ABC and 2ABc, thus 75% of the offspring should resemble the first parent, calculated by (6/8) x 100 = 75%.

Answer:

1. The proper response would be A) allows viewing of live cells, while electron microscopes do not.  

There are several benefits of light microscopes compared to electron microscopes:

• They are simpler to operate in contrast to electron microscopes.
• Light microscopes can observe both living and deceased specimens, whereas electron microscopes are limited to deceased specimens only.
• Moreover, light microscopes are significantly less expensive and entail lower maintenance costs when compared to electron microscopes.

2. The correct answer would be C) scanning electron microscope

The scanning electron microscope, or SEM, is a variant of electron microscope designed for analyzing surface texture and composition of samples. It can achieve resolutions of up to 1 nanometer.

3. The accurate answer would be 400x

The total magnification of a microscope can be determined by multiplying the power of the objective lens by that of the eyepiece lens.

Consequently, the magnification of the specimen would be calculated as 40*10 = 400x.
