20. Explain how the transfer of energy can be tracked as energy flows through a natural system. In other words, why are photosynthesis and cellular respiration together called “the energy cycle”?
Photosynthesis and cellular respiration are together called “the energy cycle” because the vast amount of biomass on Earth is sustained by these metabolic pathways and they are interrelated processes.
What are photosynthesis and cellular respiration?Photosynthesis and cellular respiration are two metabolic pathways that play fundamental roles to sustain life on the Earth.
Photosynthesis is a series of metabolic reactions through which plants and also algae generate biomass in the form of simple carbohydrates such as glucose, which is achieved using sunlight and carbon dioxide generated through cellular respiration.
Moreover, cellular respiration generates energy in aerobic organisms which requires the use of oxygen as a reactant obtained by the mechanism of Photosynthesis.
Therefore, with this data, we can see that photosynthesis and cellular respiration are fundamental processes to sustain life on the earth's planet and they are interrelated because the products of photosynthesis are used as reactants in cellular respiration.

The pH test would be used to test for acidity in a soil sample (option A).
What is pH?pH is the notation that expresses the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
Acidity of a solution refers to the state of being an acid. Using the pH scale, an acidic solution or substance will have a pH between 0 - 6.9.
pH is equal to −log {C}, where c is the hydrogen ion concentration.
Therefore, the pH test can be used to evaluate whether a soil sample is acidic.

How our body makes glucose?
It primarily originates from foods high in carbs, such as fruit, bread, and potatoes. Food moves from your mouth to your stomach via your oesophagus while you eat. It is reduced to tiny fragments by acids and enzymes there. This causes the release of glucose.
It enters your intestines to be absorbed there. It then enters your bloodstream from there. Once in the circulation, insulin aids in the delivery of glucose to your cells.
Thyroxine, a hormone produced by the thyroid gland, regulates this metabolic rate, ensuring that the body is operating at the proper rate. Tetraiodothyronine is its full name, and its chemical formula is C15H11NO4I4.
Hence the correct option is C; thyroxine.

Diabetes Insipidus is a condition that causes disturbance of water metabolism resulting in extreme thirst and excessive secretion of dilute urine. one cause is an injury to the pituitary gland resulting from head trauma.
Treatment options depend on the type of diabetes insipidus you have.
An uncommon illness called diabetes insipidus disrupts the fluid balance in the body. You create a lot of urine as a result of this imbalance. Even if you have anything to drink, it also makes you really thirsty. If you have diabetes insipidus, your body struggles to maintain correct fluid balance. When the body's fluid levels are not adequately balanced, diabetes insipidus develops.
The types of diabetes insipidus that you have will determine your treatment options.
The first-line treatment for central diabetic insipidus is desmopressin. It is a drug that functions similarly to an antidiuretic hormone.Nephrogenic diabetes insipidus treatment is more difficult and occasionally requires a combination of methods. Medication that lowers the volume of urine your kidneys produce is frequently used to treat it by medical professionals.Dipsogenic diabetic insipidus is currently not effectively treated, according to research.

In mitochondria, both cellular respiration and photosynthesis take occur. When organic molecules break down in the former, electron transport chain (ETC), energy and electrons are also released. In the latter, the electrons join the chain after being triggered by light, and the energy released is used to produce carbohydrates. A sequence of proteins that the electrons in the electron transport chain (ETC) move through raises its reduction potential, causing an energy release. Pumping hydrogen ions (H+) creates a proton gradient, which increases the acidity in the intermembrane gap by creating an electrical difference with a positive charge outside and a negative charge within.
