Mr. Rojas was looking through a microscope at some similar cells. He noticed that every cell had a different structure. What can he infer about these cells? * They are from different organisms. They have the same organelles. They have the same functions. They have different functions.

Answers

Answer 1

Answer:

Answer:

They have different functions.

Explanation:

The cells having different structures may come from the same organism and having different structures may result from having different organelles. Due to the structure function correlation in cells, it is thus likely that the different structures arise from different functions, hence cells are specialised structurally to optimise performance in their functions.

How does this sentence violate the principles of objectivity in writing a summary?

Answers

You didn't provide the sentence that is relevant in this case, however, generally if you would like to be objective in a sentence, you shouldn't include possible issues such as subjective thoughts, judgments, and similar things which have a negative impact on objectivity (and in reality destroy any remaining objectivity in a sentence).

Multiple alleles _____. a. can interact and influence a trait such as eye color, b. cannot interact to influence traitsc. that interact are always sex linked
d.are made of RNA

Answers

Answer:

The correct answer would be option A. It can interact and influence a trait such as eye color.

Explanation:

Three or more alternative alleles of a gene that can occupy the same locus known as multiple allele condition. However, only two of the alleles can be present.

The ABO blood group system and human eye color are examples of the multiple allele condition.

Eye color is determined by multiple genes. OCA2 and HERC2 Both are located on human chromosome 15. A common polymorphism in the HERC2 gene is accountable for the blue eye. A person with homozygous TT predicts likely to have brown eyes, while a person with 2 copies of C allele at HERC2 rs1293832 will have blue eyes.

Thus, the correct answer would be option A.

can interact and influence a trait such as eye color

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. Think about the gametes this parent plant will produce. List the alleles in each gamete.
