The answer is b. An animal that relies on the digestive tract for digestion breaks down food via extracellular digestion. The digestive tract uses mechanical and chemical processes to digest the food. Extracellular digestion is a type of digestion that happens in an opening as part of a digestive system where the nutrients produced from digestion is transferred to the blood or other body fluids. The digestive tract serve as the opening.

ratelena [41]
The saying it's freezing outside just means it feels very cold. It's not accurate because the temperature doesn't actually cause you to psychically freeze.

1.what did magnesium and oxygen atoms had to do to bond ?
devlian [24]

Answer:

1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).

2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.

3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.
