Answer:
Before "true" labor begins, you might have "false" labor pains, also known as Braxton Hicks contractions.
Explanation:
When a monovalent cation X binds to a divalent anion Y, a compound with the formula
would be formed.
A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be 
A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be 
Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of
would be required to successfully bind

Answer:
from producers to consumers
Explanation:
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants
