Answer:
1.ans Phylogenetic Trees
Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
2.ans Binomial Nomenclature Rules
The entire two-part name must be written in italics (or underlined when handwritten). The genus name is always written first. The genus name must be capitalized. The specific epithet is never capitalized
3.ans Dichotomous Key
A dichotomous key is a tool created by scientists to help scientists and laypeople identify objects and organisms. Typically, a dichotomous key for identifying a particular type of object consists of a specific series of questions.
C, because it protects the cell from the outside environment
the (drug and control) are the variable that you will change throught the conducted investigation.
<h2>Answer </h2>
- Hybridization
- Recombinant DNA
- Selective Breeding
<u>Explanation</u>
1. Cross-breeding; a method that unionizes gametes of differing genes to create a new individual is hybridization. It is the idea of combining atomic orbitals into different hybrid orbitals that is proper for the pairing of electrons to create chemical bonds in valence bond as per the atomic theory.
2. Cultured DNA molecules from different biological sources is recombinant DNA. They are the molecules are DNA molecules determining by laboratory techniques of genetic recombination to take mutually genetic material from various origins.
3. A process of breeding organisms because of their specific traits is selective breeding. It is the method that grants humans practice animal breeding and plant breeding to selectively develop selective over phenotypic traits
