Answer:
The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper.
Explanation:
The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper. Small Rf values tend to indicate larger, less soluble pigments while the highly soluble pigments have an Rf value near to one.
The correct answer is E. Vertebrates are all related to a common ancestor
Explanation:
According to biology and evolution, organisms from different species but that share similarities in morphology (body structures) as well as in genetics often have a phylogenetic relationship which means they descend from the same organism or share a common ancestor. This applies to multiple taxonomical levels including classes such as mammals or birds as it has been proved each of this derived from a common ancestor. Therefore, the similarity in the body structure (morphology) in all mammals suggest vertebrates are related to a common ancestor and as they evolved from this, they share similarities not only in terms of morphology but also in genetics.
Well it’s obvious that they both use Photosynthesis to make there own food, and also they both use chemosynthesis the produce there own food. Very simple. :)
I would say Diandra, because she provides the most in depth description!
Answer:
It shows their evolutionary history and their possible common ancestor.
Explanation:
Similarity of early embryos of different species is a phenomenon observed by many scientist such as Karl von Baer, Charles Darwin and Ernst Haeckel.
Karl von Baer even formulated the law of embryonic development. He explained that there is a certain embryonic form, basic form, which is similar in different species. After this stage (basic form) each species develops independent-there is a branching pattern of further development.
So, according to von Baer development goes " from the most general forms the less general".
