True or false:
Mutations can only happen during mitosis, but not meiosis

Mutations are the only way that single-celled organisms can evolve

Mutations that occur in body cells can be passed on to offspring

Variations are necessary for natural selection to take place

Sexual reproduction is the ultimate source of variation on this planet

A mutation can be passed on to other cells through mitosis

In sexual reproduction, the offspring receives most of its DNA from one parent

Bacteria can reproduce sexually or asexually

Genetic recombination takes place during mitosis

Mutations can occur randomly during DNA replication of cell division

Fertilization joins genes from both parents to create the genetic code of an offspring

In populations made by sexual reproduction, each organism is unique

The use of logic making empirical observations and performing dissections were all part of the scientific studies by

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.
