Answer:
B
Explanation:
Valleys are created by streams of running water
<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
D) Robert Hooke first discovered cells when observing cork under the microscope.
Monosaccharides<span> (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as </span>starch<span> and cellulose).</span>
