CLOZE - Reactions and the Law of Conservation of Matter Name: salome
All the time, chemical reactions are taking place. With or without our notice,
substances are being broken apart and new substances are being
In order to understand or describe these reactions, scientists use chemical
A chemical equation is exactly what it sounds like, an equation about
(or chemical
). Chemical equations contain symbols for the
elements, compounds, or
involved. Chemical equations also
contain the number or amount of each substance involved.
An arrow shows the difference between the reactants (the items
together) and the products (the items that are
.). Reactants are
the substances that are
apart or combined in a reaction. They
are on the
side of the arrow,
Products are located on the right side of the arrow and they are the
substances that are formed in a chemical reaction.
Let's look at an example:

The phenotype of the offspring will be 100%tall

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
