The following experiment seeks to investigate the rate of growth of mice to the grams of food per day. The experiment lasts two weeks or 14 days and measures the weight of the mice each day.
Place two mice in a glass box labeled A. Provide 4 grams of food 12 hours each day for 14 days
Place two other mice in a glass box labeled B and administer 8 grams of food 12 hours each day for 14 days
Delegate your assignment to our experts and they will do the rest.
Place two mice in another glass box labeled C and provide 1 gram of food 12 hours in a day for 14 days
Hypothesis
The weight of the mice will grow relative to the number of grams of food they receive in 14 weeks.
Dependent Variable
The mass of the mice
Independent Variable
The mass of the food
Control and Experimental Group
The experiment entails three different pairs of mice that control each other. Mice take approximately 4 gram of food and therefore the box with 4 gram of food will control the other two boxes.
Controlled Variables
Box A contains 4 grams of food, B contains 8 grams of food, and C contains 1 gram of food.
Results
The results indicate that there was relatively no change in mass for Box A, there was an increase in mass for Box B, and there was a reduction in mass for Box C.

The burning of fossil fuels releases hazardous gases like carbon dioxide into the environment leading to the corrosion of the ozone layer, and this permits harmful UV radiation to venture into the earth's surface and cause global warming. The ozone layer of the atmosphere provides a protective cover for the earth, reflecting excess heat out of the earth’s atmosphere and only allowing sufficient energy from the sun into the earth's surface for the sustenance of life. The greenhouse effect refers to a natural process that results in the warming of the earth's surface. Greenhouse gases like carbon dioxide, methane, nitrous oxide and water vapor all contribute to the general warming of the earth's surface. Global climate change occurs as a result of all the warming and cooling effects of the various variants and reactants on the earth's surface. For instance, carbon is an essential element responsible for the carbon cycle and responsible for warming the earth and altering the climate.
According to the second law of thermodynamics, the cumulative entropy within an isolated system cannot decrease regardless of the period. Therefore the entropy is constant, provided all the processes are reversible. Therefore eating a plant-based diet is environmentally beneficial since the process leads to the preservation of nutrients, which is preserved in the exchange between the producer and the final consumer. The systemic preservation of mineral resources within the trophic level ensures that the omnivores and the herbivores in the food chain ensures the gradual preservation of energy. According to the law, systems that are isolated are automatically drawn towards the direction of thermodynamic equilibrium. This situation represents a state of maximum entropy. Therefore, taking a plant-based diet ensures the continuation of the plant species and the preservation of the consumer species through the mutual relationship between them.
On the one hand, density-independent factors are responsible for the exertion of influence as well as the effect on the population, and this is regardless of the density. On the other hand, density-dependent factors perform the opposite effect on the population. Weather and climate are examples of density-independent factors that affect the pygmy-deer population, as outlined in the case example. The period of extinction from the Island allowed the pygmy-deer population to earn the status of endangered species upon re-establishment on the island. The new status of the pygmy-deer population allows them to flourish since they are protected from extinction. However, the start of the winter disrupts the peace and harmony they enjoy and forces them to survive on riding bird feeders and eating bark. The results of the factors dependent on the density of the pygmy-deer population become intense upon the increase in the pygmy-deer population.
