There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.

The enzymes are the chemical molecules that alter the chemical reaction when added in a specific amount, it either increases the reaction, or decrease it.

There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.

Because the substrate concentration increased each time, there was a greater chance that the substrate would bind to the active site and carry out the reaction.

Thus, this way the enzyme concentration affects the reactivity.

The emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.

The term dissolved oxygen refers to the amount of oxygen that is present in  a water body. Now, we know that the addition of organic matter into water requires oxygen to break it own thus the dissolved oxygen content will go down in response to the added organic load.

Geopolitics can be given as the study of the influence factors such as geography, economics, and demography on politics and especially the foreign policy of a state. Thus, the correct option is D.

Around the turn of the 20th century, the Swedish political scientist Rudolf Kjellén first used the term "geopolitics," which expanded throughout Europe in the years between World Wars I and II (1918–39) before becoming widely used during the latter. Geopolitics is frequently used as a colloquial term for international politics in modern speech.

After World War II, geopolitical theory lost favor due to its links to imperialistic Japanese and Nazi German aggression as well as because the development of nuclear weapons and ballistic missiles diminished the importance of geographical variables in the global strategic balance of power.

The definition of geopolitics stands for the analysis of the factors including geography, economics, and demography on politics and foreign policy. Thus, option D is correct.

Answer:

Chemical energy

Yes, food serves as a basic source of the nutrients and energy needed to maintain and grow the body. Food contains what is referred to as "chemical energy" in terms of energy. This is nothing more than the bonds between the atoms that make up the specific food item, which the body may break down to release energy that it can use to create, repair, and ensure appropriate bodily function. This chemical energy is ultimately sunshine energy, which plants have the extraordinary capacity to use and store in the chemical compounds they produce, mostly in their leaves, using sunlight, water, and atmospheric carbon dioxide. Food does indeed contain energy, but that energy ultimately originates from the sun. Since people have known this for thousands of years, many civilizations revere the sun, along with water, air, and of course fire, as the source of life. For the body to function, energy is required by the muscles, brain, heart, and liver. The food we eat provides us with this energy. Our bodies break down the food we consume by combining it in the stomach with fluids (acids and enzymes). The carbohydrate (sugars and starches) in food is broken down into another form of sugar, termed glucose, during digestion in the stomach. The glucose is absorbed by the stomach and small intestines before being released into the circulation. Upon entering the bloodstream, glucose can either be utilized right away for energy or stored for later use. But in order to utilize or store glucose for energy, our systems need insulin. When insulin is absent, glucose remains in the circulation, which raises blood sugar levels. The glucose is burnt inside of your cells to create heat and adenosine triphosphate (ATP), a chemical that stores and releases energy as the cell requires. Either oxygen is present throughout the process of converting glucose into energy, or it is not. In the mitochondria, which are microscopic structures located in the gel-like fluid that fills every cell, glucose is transformed into energy using oxygen. This conversion results in waste products including water and carbon dioxide as well as energy (ATP, heat). Without oxygen, red blood cells convert glucose into energy because they lack mitochondria. ATP, heat, and lactic acid are produced as a result. Muscle cells also use glucose as a source of energy. Muscle cells are, well, double-jointed when it comes to converting glucose into energy. They can metabolize glucose with oxygen because they contain mitochondria. However, if the muscle cell's oxygen level plummets, the cells can simply convert glucose into energy on their own without it. When you have been working out so hard that you are physically out of breath, this is most likely to occur.
