EXPLAIN The scuba diver is a living system. The scuba gear, or self-
contained underwater breathing apparatus, is a system of air exchange.
How are these two systems interacting? What are the inputs and outputs of
these systems?
Pt.I
All living things needs some form of oxygen to live. In talking about a scuba diver, we are talking about a human, who uses their lungs to breathe, and did not develop the ability to breathe under water. Instead, when in a body of water, we tend to hold our breaths until an opportunity arises for us to exchange our carbon dioxide for oxygen.
Take into account the scuba gear. The scuba gear fits the user, and has a number of protection, including the suit counter-balancing any pressure applied by the deep, and the tank providing much needed oxygen to the user during delayed periods within the water.
Pt.II
How does these two systems interact?
Like as a human is breathing on land or even swimming, the human expels carbon dioxide, which forms into "air bubbles" that are then expelled into the water surrounding. The user then draws air from the pressurized air tank, and is able to breathe as such. This allows the user to stay underwater for much longer than just one breathe, and is able to travel farther inside the deep.
Inside this system, the Oxygen is first input into the oxygen tanks, which are then used by the diver. The diver would draw the oxygen from the tank (output), and he will then expel the used air into the surrounding water.

The function of the citric acid cycle is to transfer the acetyl group gained from glycolysis to molecules of pyruvate. hydrolyze glucose in the presence of oxygen to obtain two pyruvate molecules. remove hydrogen atoms from organic molecules and transfer them to coenzymes. produce water. produce carbon dioxide to balance the oxygen requirement for cellular respiration.
Answer:
The function of the citric acid cycle is to produce carbon dioxide to balance the oxygen requirement for cellular respiration.
Explanation:
In the citric acid cycle, pyruvate is first decarboxylated, leading to the production of CO₂, NADH, and the energy-rich substance acetyl-CoA. The acetyl group of acetyl-CoA then combines with the four-carbon compound oxaloacetate, forming the six-carbon compound citric acid. A series of reactions follow, and two additional CO₂ molecules, three more NADH, and one FADH are formed. Ultimately, oxaloacetate is regenerated to return as an acetyl acceptor, thus completing the cycle .

In the hierarchy of biological organization, an organ is composed of several ______ interacting and working together.
Answer:
tissues
Explanation:
Tissues(made of cells with specific functions)make organs
In the hierarchy of biological organization, an organ is composed of several tissues interacting and working together.
What are tissues?Tissue is basically a group of or collection of cells with somewhat identical structures that work together as a unit.
The intercellular matrix is basically a nonliving material that encompass the spaces in between the cells. This may be profound in some tissues while being scarce in others.
Tissue is classified into major four kinds namely connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
Connective tissue supports as well as connects other tissues (bone, blood, and lymph tissues). Epithelial tissue serves as a protective layer.
An organ is a collection of tissues that structurally form a functional area specialized to take part in a specific function in biology. Organs include your heart, kidneys, and lungs.
Thus, the answer is tissues.

A scientist has a hunch that students learn best when they write down information with a pencil or pen. He organizes his students into two groups. Half of his students use pencil use pencil or pen to take notes in class every day and the other half type their notes on their laptops. At the end of the unit, all the students take the test and he looks at their scores to determine the outcome of the experiment. What is the dependent and independent variable? 100 points!!!!
Answer:
The correct answer would be :
independent variable : use of pen or pencil
Dependent variable : test scores (test of learning ability)
Explanation:
Independent variable of any scientific investigation or experiment is a variable that is manipulated or changed to see the change in dependent variable. In this case the variable that is changed or manipulated is use of pen or pencil to see that effect on learning ability.
Dependent variable is something that is measured or calculated to find the effect of the independent variable. In this case the dependent variable is test score that will provide idea that if hunch of scientist is true or not.
Thus, the correct answer would be :
independent variable : use of pen or pencil
Dependent variable : test scores (test of learning ability)

Which scenario would be most appropriate to study using a natural experiment? * the effects of an herbicide on human health the influence of sleep on exam performance the effects of an earthquake on blood pressure
Answer:
C. the effects of an earthquake on blood pressure
Explanation:
Natural experiments are observational studies in which participants are randomly assigned to groups that allow the researcher to draw causal relationships between an event and a factor. These experiments are used in studies where it would be unethical and unacceptable to subject human participants to such conditions. It is most times applied in epidemiological studies.
Since the researcher cannot control an earthquake which is a natural occurrence, this can be rightly described as a natural experiment. Controls are not used in this type of experiment.

Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?
a. Column A should be “Time,” and Column B should be “Position.”
b. Column A should be “Position,” and Column B should be “Time.”
c. Column A should be “Velocity,” and Column B should be “Speed.”
d. Column A should be “Speed,” and Column B should be “Velocity.”
Answer:
Column A should be "Time," and Column B should be "Position"
Explanation:
In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.
Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".
Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.
Option C) and D) are not possible, as both of them are variables that depend on time.

what is the result of too much or too little Dark energy:
Answer:
Dark Energy, Dark Matter
In the early 1990s, one thing was fairly certain about the expansion of the universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Granted, the slowing had not been observed, but, theoretically, the universe had to slow. The universe is full of matter and the attractive force of gravity pulls all matter together. Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the universe was actually expanding more slowly than it is today. So the expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating. No one expected this, no one knew how to explain it. But something was causing it.
Eventually theorists came up with three sorts of explanations. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. Theorists still don't know what the correct explanation is, but they have given the solution a name. It is called dark energy.
