Answer:
There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera
Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.
For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.
It shows divergent evolution and supports that these organisms have evolved from a common ancestor.
Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.
For example:
- The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
- Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.
Answer:
Explanation:
rna is produced in the transcription stage of protein synthesis whereby complementary base pairing occurs
Answer:
The correct option is A. Bacteria are prokaryotes and protists are eukaryotes
Explanation:
The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.
The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.
Therefore the answer that best explains the difference between both protists and bacteria
Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.
An exoskeleton is the outer skeleton of an animal to protect them. An exoskelton is also called a shell.
Answer:
-Plant cell has a cell wall and animal cell does not.
-Large vacuole present in plant cell and little or no vacuoles present in animal cell.
