The odd hormone insulin Cortisol
Explanation
Cortisol is known as the odd hormone because it is release when someone stressed and it interfer the brain activity by making the person feels like blank. The low cortisol level causes decrease appettite, fatigue, weightloss, different skin problem, low blood sugar and many more. The high level of cortisol causes the weight gain, acne, muscle weakness, thinning skin, flused face and other type of causes.
Among insulin, cortisol, glucagon, and calcitonin, cortisol is the 'odd one out'. It is classified as a corticosteroid, whereas the others are peptide hormones.
The odd hormone in the list of insulin, cortisol, glucagon, and calcitonin, is cortisol. While insulin, glucagon, and calcitonin are all peptide hormones, cortisol is a corticosteroid, a different type of hormone, released by the adrenal cortex in response to long-term stress. Insulin is produced by the beta cells of the pancreatic islets and regulates blood glucose levels. Glucagon, produced by alpha cells of the pancreas, also helps in regulating blood glucose levels. Calcitonin is a hormone produced by the parafollicular cells of the thyroid gland and functions to lower blood calcium levels. Though all these hormones play integral roles in the body, cortisol, as a corticosteroid, is structurally and functionally different from the others, making it the 'odd one out'.

Fossil fuels are made from decomposed plants and animals found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil and natural gas are examples of fossil fuels.
A fossil fuel is defined as a hydrocarbon consisting of naturally occurring material in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, oil and natural gas.
The four main types of fossil fuels are
1. Petroleum
2. Coal
3. Natural gas
4. Oil emulsions.
They normally have a variety of physical, chemical and other essential properties. The most unfair thing about fossil fuels is that they are not green. Fossil fuels are made from plants and animals that decompose.
Thus, fossil fuels are made from decomposed plants and animals found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil and natural gas are examples of fossil fuels.

Fossil fuels, like coal, oil, and natural gas, are the primary sources of energy for electricity generation, transportation, heating, and industrial processes, but their use also poses environmental challenges.
The relationship between fossil fuels and energy is foundational to modern society. Fossil fuels, including coal, oil, and natural gas, serve as the primary sources of energy for many aspects of our daily lives and industrial processes. Here's how this relationship works:
1. Energy Generation: Fossil fuels are burned in power plants to generate electricity, which powers homes, businesses, and industries. They are also used as fuels in vehicles, airplanes, and ships for transportation.
2. Heating and Cooling: Fossil fuels are essential for heating homes, providing hot water, and running HVAC systems, ensuring comfort and warmth in colder climates.
3. Industrial Processes: Many industrial processes rely on fossil fuels for heat, steam, and electricity, including manufacturing, chemical production, and refining.
4. Electricity Grid: Fossil fuels play a crucial role in stabilizing the electricity grid, providing reliable power during peak demand.
However, the extensive use of fossil fuels also has environmental consequences, including air pollution, greenhouse gas emissions, and climate change.
As a result, there is a growing emphasis on transitioning to cleaner and more sustainable energy sources like renewable energy (e.g., solar, wind, and hydropower) to mitigate these environmental impacts and ensure a sustainable energy future.

Rough ER is connected to the nuclear membrane and to smooth ER.
It is a membranous organelle that is a part endo-membrane system in the cell. It is connected to the nuclear membrane and arises as flattened projections. These organelles are attached to ribosomes and therefore, called rough.
The rough endoplasmic reticulum has many folds that are connected to smooth endoplasmic reticulum as these lack ribosomes on its surface.

D.
reproduction
Reproduction is the process in which an organism makes a new organism. Thus, the correct option is D.
Reproduction is the process of production of new organism. There are two main types of reproduction including sexual and asexual reproduction.
In sexual reproduction, an organism combines the genetic information from each of the two parents and is genetically unique from both the parents. In asexual reproduction, one parent copies itself to form a genetically identical offspring called as clone.
Reproduction ensures the continuity of the species and keeps the species from becoming extinct. It plays a role in evolution of the species as it creates variations through genetic recombination.
Therefore, the correct option is D.
