Answer:
DNA
Explanation:
RNA is not a double helix
Uracil is on the RNA, this is a picture or DNA. Uracil is just one of the nucleic bases
This is not a monomer; it's actually a polymer
It is DNA because it is a double helix structure held together by the four nucleic bases.
Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).
We can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.
<h3>Why would this cause a decline in the population of coyotes?</h3>
The wolf, in most ecosystems, is considered to be the top predator. This means that it will also hunt and consume the coyotes. This alone would cause a decline in the coyote population as they now have an additional predator hunting them. Also, the wolves would be competing with the coyotes for food sources, furthering the impact on the coyote population.
Therefore, we can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.
