Ascientist claimed that he had cloned a guinea
pig to produce two offspring, a male and a
female. the claim is not valid because
(1) guinea pigs can reproduce both sexually and
asexually
(2) the two offspring are not identical copies of
the original guinea pig
(3) each of the offspring had half the genetic
information of the original guinea pig
(4) none of the genetic information came from
the original guinea pig

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.

Explain why the plants cortex would serve as the best food source for animals
