Answer:
D. Single-stranded
Explanation:
DNA normally has a <em>double-stranded </em>structure. Each strand is composed by nitrogenous bases, sugars and phospates; strongly binded together by chemical bonds. The strands are bonded to each other, however, by relatively <em>weak interactions </em>between the hydrogen atoms in the nitrogenous bases in each strand. The energy supplied by heat is enough to break the weak interactions between hydrogens, but not enough to break the strong chemical bonds that make up the strands.
Answer:
spend time removing introduced species, which can mean physically weeding invasive plants or trapping invasive animals. ... Others work to reduce harvesting directly or to reduce the incidental catch of nontarget species.
Answer:
Animals and Plants

Answer: A molecule of a compound is formed by bonding atoms of different elements through chemical bonding. The number of each type of atom present in one molecule of the compound is represented by a suffix to the symbol of the element which representing the formula of the compound. C12H22O11 is a formula of a compound consists of carbon, hydrogen and oxygen elements. There are 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms in one molecule of C12H22O11. Therefore, the numbers 12, 22 and 11 represent number of atoms.
