Answer:

Domain

Explanation:

It is common to find in textbooks the classification of living organisms into five kingdoms: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae and Kingdom Animalia. It is now known that this classification has some serious flaws and that some kingdoms are no longer considered.

A widely accepted classification today is one that comprises one category above the kingdoms: domains. This classification was proposed by Carl Woese in 1977 and is based on molecular phylogeny data. According to Woese, there are three domains: Archaea Domain, Bacteria Domain, and Eukarya Domain.

What process occurs in prokaryotes but not in eukaryotes?
Naddika [18.5K]

Explanation:

In the given question, the options are not provided in the question and neither they are found anywhere therefore based on the previous knowledge this can be answered.

Since both the prokaryotes and eukaryotes are living therefore they perform the metabolism or chemical reactions in the form of process.

Both eukaryotes and prokaryotes perform almost similar process like the cellular respiration, photosynthesis by green colored organisms, the Central dogma related process like the replication, transcription and translation.

The central dogma related processes differ in these process only in terms of the site they are performed and a few modifications which are characteristics of the eukaryotic cells.

In prokaryotes, the transcription and translation are coupled and takes place in the cytosol whereas in eukaryotes transcription in the nucleus and translation in the cytosol.

Also in eukaryotes, modifications like the splicing, alternative splicing, capping and tailing are observed which are not observed in the prokaryotes.

What is the probability that the offspring will have purple flowers?; What is the phenotypic ratio for the purple flowers?; What
Luda [366]

The probability that the offspring will have purple flowers is 50% chance Let's go ahead and assume that:

The allele A corresponds to the color of flowers.

As a result, A would stand in for the alternate white hue and represent the dominating purple color.

According to the aforementioned hypotheses, a white flower would have the genotype aa while a heterozygous purple blossom would have the genotype Aa.

Now let's connect the two flowers:

Aa x aa

Aa Aa aa aa

The genotypes, phenotypes, and odds of the offspring would be as follows based on the cross's outcomes:

Purple color, Aa; 1/2

white flower color, aa, 1/2

In other words, there is a 50% chance that the cross will result in offspring with the flower colors purple (genotype, Aa) and white (genotype, aa).
