Answer:
A. They have the same function
B. They have evolved independently
C. They indicate an evolutionary relationship
Explanation:
- Analogous structures are structures with a different embryonic but have evolved to perform similar function.
- <em><u>Analogous structures are a result of convergent evolution which is the independent evolution of similar features in species of different lineages or different embryonic origin.</u></em>
- Examples of analogous structures include; wings in flying animals like bats, birds, and insects, and fins in animals like penguins and fish.
Answer:
Lysine
Explanation:
lysine residues on the histone tails of the octamer cn be activated by both acetylation and methylation patterns to influence accessibility or silencing of the genes respectiviely. for example, acetylation of H3K27 (histone 3 lysine residue 27) brings about a region of active chromatin allowing access to transcription activity while its trimethylation will cause silencing of the associated gene at that particular area (no expression of that gene)
Answer:
Chordates
Explanation:
The notochord is a flexible, rod like supporting structure, running dorsally for almost the whole length of the body. This is a distinctive feature of a chordate / animals with a back bone (vertebral column) Such animals belong to phylum Chordata.
A large central vacuole, and chloroplasts.
Answer:
The answer is A.
Explanation:
Phylogenetic trees are only concerned with hard data (time points of when species evolve) and not soft data like how great a species is.
