Starches are the most commonly consumed type of carb, and an important source of energy for many people. Cereal grains and root vegetables are common sources.
That would be genetic engineering. This study involves the use of DNA and genes.
The answer would be apples.
<span>hirschsprung disease causes some part of the colon unable to move. This makes it prone to obstruction. Low-residue diet will restrict food that has fiber. The aim of this diet is to reduce the feces produced so it won't obstruct the colon. Fruit like apples has high fiber, so its residue is not low. Grains definitely a bad choice as its fiber is very high.</span>
Answer:
Calcium becomes an ion with a charge of 2+
Oxygen becomes an ion with a charge of -2
Explanation:
since calcium lost two electrons, it has 20protrons, but only 18 electrons. this makes calcium a positive ion with a charge of 2+
An oxygen molecule consists of two oxygen atoms that have a double bond between each other and share valence electrons. the oxygen ion is formed when the atom of oxygen gains two valence electrons. this results in an oxygen ion with a charge of -2
