What is the ancestor of eukaryotes?
Archaebacteria is probably more likely to be the ancestor of eukaryotes because of certain similarities, such as the ribosome of the two groups being much more similar to each other than the ribosomes of bacteria.
Explain what the terms eukaryote and prokaryote suggest about their evolution?
The terms eukaryote and prokaryote refer to the two distinct types of organisms found in the natural world. Eukaryotes are organisms that have a membrane-bound nucleus, while prokaryotes are organisms that lack a membrane-bound nucleus. This difference in structure suggests that the evolution of eukaryotes, which are more complex and structurally organized, preceded the evolution of prokaryotes, which are simpler and more primitive. Eukaryotes are believed to have evolved from an ancestor that contained a nucleus, which was a critical step in the evolution of life as it allowed for more efficient storage and processing of genetic information. Prokaryotes, on the other hand, had no nucleus and were likely the first form of life on Earth. This suggests that the evolution of prokaryotes followed the evolution of eukaryotes. Overall, the terms eukaryote and prokaryote suggest that eukaryotes are more complex and evolved prior to prokaryotes, which are simpler and more primitive.
The fact that all organisms have DNA as their genetic material is evidence that?
We all current life has a single common ancestor.
How would you know if organisms shared a common ancestor?
The closer the DNA pattern (the nucleotide base pairing), the closer the species from a common ancestor.
What does the main trunk at the bottom of a phylogenetic tree represent?
The last universal common ancestor.
What is the ancestor of eukaryotes?
Archaebacteria is probably more likely to be the ancestor of eukaryotes because of certain similarities, such as the ribosome of the two groups being much more similar to each other than the ribosomes of bacteria.
Homologous structures in organisms suggest that the organisms?
common ancestor
How the plants come in earth?
The ancestor of plant is from ancestor prokaryote and after engulfed and undergone symbiotic relationship with aerobic heterotrophic prokaryote and photosynthetic prokaryote it become plant on the earth.
Which organisms have possible common ancestor?
All of them
What are Descendant organisms?
Descendant organisms are organisms that share many in common because they share a common ancestor.
Do some bacteria have chlorophyll in chloroplasts so they can conduct photosynthesis.?
No, bacteria generally do not have chloroplasts to begin with. Photosynthetic bacteria contain bacteriochlorophyll, which is similar to the chlorophyll found in plant cells that allow photosynthesis to take place. One distinct phylum of photosynthetic bacteria, known as cyanobacteria, are thought to be the ancestor organisms that eventually evolved into the chloroplasts that are found in modern plants.

What is the definition of ancestral trait?
An ancestral trait is a trait that is shared by a group of organisms and their common ancestor. It is a characteristic that has been inherited from a common ancestor and has been passed down through generations without change.
The fact that all organisms have DNA as their genetic material is evidence that?
We all current life has a single common ancestor.
How can you use classification to tell how closely organisms are related?
Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.
What is an evolutionary?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
How would you know if organisms shared a common ancestor?
The closer the DNA pattern (the nucleotide base pairing), the closer the species from a common ancestor.
