Answer:

The correct answer will be- study of Ribosomal RNA (rRNA) genes using Polymerase chain reaction.

Explanation:

Carl Woese is known for his formation of a new tree of life based on the study of the evolutionary molecule called Ribonucleic acid.

He studied the genes of the ribosomal RNA and compared them and found a new group of an organism called Archaea.

Archea does not contain a nucleus and are similar to bacteria in appearance but the genetic differences of the genes of the ribosomal RNA excluded them from bacteria and eukarya ad were placed in archaea.

Thus, the study of Ribosomal RNA (rRNA) genes using Polymerase chain reaction.

The Venn diagram represents two eukaryote kingdoms. Based on the characteristics shown, A represents __________ and B represents

kumpel [21]

Answer:

The Venn diagram shows characteristics of two types of living organisms, where A represents plants (Reino Planatae) and B fungi (Reino Fungi) (option A).

Explanation:

In the taxonomic classification of living organisms, the classification by kingdoms tends to compare the morphological and functional characteristics of the species, in addition to their genetic lineage.

In the Venn diagram (image):

A represents the Plantae kingdom because its cells have chloroplasts with chlorophyll, cell wall of cellulose and functionally autotrophic, characteristics linked to plants.
B in the diagram represents fungi (Fungi Kingdom) due to the presence of hyphae, cell wall of chitin and being heterotrophic.

The two circles in the diagram coincide in the cellular elements that both organisms have in common, in addition to being Eukaryotes.

Mendel observed a 9:3:3:1 ratio of offspring when studying different traits. What would he have concluded if he had observed a 3

ANTONII [103]

Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.

Explanation:

The 9:3:3:1 ratio observed by Mendel helped him to form his Law of Independent Assortment which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.

Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form the Law of Segregation, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.

However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.
