Answer:
The correct answer is option D, that is, a greenhouse gas that traps heat in the atmosphere.
Explanation:
A natural phenomenon in which the atmospheric gases captivates heat and permits Earth to retain enough solar energy to be livable is termed as the greenhouse effect. The greenhouse gases are the methane, carbon dioxide, nitrous oxide, and other gases, which gathers in the atmosphere and produces a heat-reflective layer that helps in trapping sunlight and keeps the Earth warm.
Of these greenhouse gases, carbon dioxide is the largest contributor to climate change. It is largely emitted at the time of burning fossil fuels like natural gas, oil, and other carbon-rich sources. Due to this, the level of carbon dioxide increases in the atmosphere resulting in the global phenomenon termed global warming.

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.
is there only one way to conduct a scientific experiment why or why not
Answer:
there is more than one mode to conduct an experiment in order to obtain the same results
Explanation:
The scientific method is a methodology used to minimize the bias in the experimentation procedure in order to test a given hypothesis. The scientific method has several steps:1- to raise a hypothesis, 2-to design the experiment, 3- to perform the experiment, 4-to collect data and 5-to analyze results (conclusions). The main aim of the experiment is to obtain data that can be used to confirm (or reject) the hypothesis, which must be testable and falsifiable to be valid. In consequence, the scientific method can be cataloged as an iterative method because different experiments can lead to the same results.
A scientific experiment can be conducted in different ways, with the aim of trying to check the theories and hypotheses, to observe the results of the same.
An experiment is defined as that process by which one or more independent variables are intentionally manipulated to verify or correct the postulates of the hypotheses that have been created. Its goal is to accumulate reliable information.
Scientific experimentation collects the different methods / ways used by researchers to test their theories and assumptions regarding their objects of study, through the repetition of certain phenomena observed in nature, in the controlled environment of the laboratory.
For a scientific experiment to be valid, however, it must comply with the steps of what is contemplated in the scientific method: a series of logical connections and steps to follow to study a phenomenon objectively and verifiably.
Therefore, we can conclude that there are more than one way to conduct a scientific experiment for the verification of the hypothetical knowledge of the researchers following the steps in the scientific method.

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.

Answer:
Liver-lung migration
Explanation:
Ascaris lumbricoides is also known as round worm and humans get transmitted through contaminated food and water.
When they are ingested, the hatched larvae then penetrate into the intestinal mucosa and are carried to the liver through the portal venules and are then moved to the lungs . When they are in the lungs they rupture which results in them being coughed up and swallowed. After which they mature, mate and deposit eggs which are excreted and the cycle goes on when humans ingest food contaminated with the eggs.
They cause abdominal pain, nausea and anemia and are treated through drugs such as mebendazole.

When the blood conce
Explanation:
When the blood ca+ concentration falls below the standard of 4.4-4.5mg/dL,that is below 4.4mg/dL the clinical condition is called hypocalcemia. It is caused by hypothyroidism,due to malfunction of the parathyroid gland.
Generally, Ca+ is needed for contraction of muscles by causing the fusion of the vesicles containing neurotransmitters to the presynaptic membrane for the passage of neuro transmitters to fuse with the receptors on the sarcolemma to initiate muscular contractions by opening of ligand gated Na+. It also interact with the ligand gated sodium ion channels
Generally,Ca+ inhibits depolarization of ligand gated Na+ channels. Thus blocks the opening of these channels and therefore the rate of excitability.Therefore, If the is low serum levels of Ca+,There is increased in the threshold of depolarization because more ligand gated Na+ channels are opened,Thus their is increased excitability of nerves and muscles fibres therefore in the clinical manifestations listed above.
It can be treated with infusion of Ca+ into the blood.

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 .
