11. Variations of an atom that differ in the number of neutrons are called These variations can be stable or unstable. When a
variation of an atom has an unstable nucleus due to the number of neutrons, it is
called a
and emits an energy called
While this energy is dangerous to cells and their DNA,
it can also be used for various practical tasks in fields such as
and
12.
are small particles that have a negative charge and
orbit around the nucleus of an atom. They do not contribute to the atomic mass/
weight.
13. Electrons orbit around the nucleus of an atom in energy levels called
The first shell orbiting around the nucleus can hold a
maximum of
electrons. The second and third shells can hold a
maximum of
electrons. The outermost shell of an atom is
called its
shell and the electrons in that shell are called
electrons.
14. In a neutral atom (atom with no overall electrical charge), the number of
and
is equal.
15. If an atom's outside orbital is FILLED with electrons, that atom is said to be
and
_. Cite an example:
16. If an atom's outside orbital is NOT filled with electrons, that atom is said to be
and
_. All of the atoms found in living
organisms are in this category because chemical reactions are necessary for life.

Which list shows the levels of organization of an organism in hierarchical order from left to right, from the smallest to the most complex?

Which best explains how a heat pump can heat a room? cold air from the house is moved through pipes, where it absorbs thermal energy. warm air from outside is pushed into the house to replace the cold air. combustion warms the air when chemical energy is transferred to thermal energy. fuel is used to move a piston, which pushes warm air into the house.

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
