Answer:
The observation of studying the composition of the oxygen and the other chemical that is getting cycled.
Explanation:
If the student tests their hypothesis and collects the data.
<span>The liquid rise up through the dip tube when the valve is opened. </span>The propellant gas wants to expand as much as it can, so if the valve is open, the propellant expands and pushes the spray up out of the can making more room for itself to expand.
Answer:
As the diagram for the question is not given, lets answer the question generally.
Explanation:
Energy in a system is neither created nor destroyed. Yet, the energy can be changed from one form to another. If in the beginning, at a point a, an object has a potential energy of 100 joules, then at point b the kinetic energy of the object will be subtracted from the total 100 joules of energy present in the beginning. This is because the potential energy will be being changed to the kinetic energy and no new energy will be created or destroyed.
<span>The set point theory is when your metabolism adjusts to keep your body weight consistent. It says that humans have predetermined body weight or fat content and they body closely regulates your metabolism accordingly.</span>
<span>Levels of OrganizationIn unicellular (single-celled) organisms,
the single cell performs all life functions. It functions independently.
However, multicellular (many celled) organisms have various levels of
organization within them. Individual cells may perform specific
functions and also work together for the good of the entire organism.
The cells become dependent on one another.Multicellular organisms have
the following 5 levels of organization ranging from simplest to most
complex:<span><span>LEVEL 1 - Cells<span><span>Are the basic unit of structure and function in living things.
</span>May serve a specific function within the organismExamples- blood cells, nerve cells, bone cells, etc.</span></span><span>LEVEL 2 - Tissues<span>Made up of cells that are similar in structure and function and which work together to perform a specific activity
Examples - blood, nervous, bone, etc. Humans have 4 basic tissues: connective, epithelial, muscle, and nerve.</span></span><span>LEVEL 3 - OrgansMade up of tissues that work together to perform a specific activityExamples - heart, brain, skin, etc.</span><span>LEVEL4 - Organ Systems
<span>Groups of two or more tissues that work together to perform a specific function for the organism.
Examples - circulatory system, nervous system, skeletal system, etc.
The
Human body has 11 organ systems - circulatory, digestive, endocrine,
excretory (urinary), immune(lymphatic), integumentary, muscular,
nervous, reproductive, respiratory, and skeletal.</span></span><span>
LEVEL 5 - Organisms
<span>
Entire
living things that can carry out all basic life processes. Meaning they
can take in materials, release energy from food, release wastes, grow,
respond to the environment, and reproduce.
<span>Usually made up of organ systems, but an organism may be made up of only one cell such as bacteria or protist.
</span>Examples - bacteria, amoeba, mushroom, sunflower, human</span></span></span></span>
