Answer: Because every zone of the ocean has the combination of the organisms living there that are adapted to the light, pressure, and temperatures.
Answer:
B) A worm that lives inside a bear.
Explanation:
A parasite is a living organism that lives inside or outside of another organism called a HOST in order to obtain nourishment from such organism. A parasite that lives inside its host is called ENDOPARASITE while a parasite that lives outside its host is called ECTOPARASITE.
In this question, a worm that lives inside a bear is a PARASITE because it is living inside the bear, which is the host in order to obtain nourishments. Note that, the answer is not option D because the bear is a HOST not a parasite.
2 molecules of amino acids joined to form a peptide bond and the resulting molecule would be dipeptide.
Explanation:
When two amino acid molecules combine they form peptide bonds and in the process release one water molecule and a dipeptide is formed. This process is called dehydration synthesis. Many amino acid molecules eventually connect by peptide bonds resulting in a protein molecule.
If an atom is unstable it can become stable by the gain or loss of electrons.
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
