Q 16 Which description correctly differentiates between the structure and function of Organelle B?
Organelle B
A This organelle is composed of two membranes. It is the site of photosynthesis
This organelle contains mostly water and nutrients which aid in the rigidity of the
cell
This organelle contains chromosomes and proteins. It directs cell activities and
stores genetic information
This organello is composed of two membranes. Reactions inside it release energy
that can be used for coll processes.

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.
