Question

Which of the following describes homeostasis?
A. An animal maintaining a home range.
B. A population maintains constant population size.
C. Females remain in their parent's territory.
D. Plants cease to grow at a maximum height.
E. Maintaining an internal environment in a steady-state

Answer 1

Liquid and solid particles make up our blood. Plasma, the liquid component of blood, is made up of water, salts, and protein. Plasma makes up more than half of your blood. Red blood cells, white blood cells, and platelets make up the solid component of your blood. RBCs are the cells that transport oxygen from your lungs to your tissues and organs.

Complete answer:
Homeostasis is the state of constant internal, physical, and chemical circumstances that biological systems sustain. This is a state of optimal functioning for the organism in which numerous variables, such as body temperature and fluid balance, are maintained within predetermined parameters (homeostatic range). The pH of extracellular fluid, sodium, potassium, and calcium ion concentrations, as well as blood sugar levels, are all factors that must be maintained despite changes in the environment, food, or degree of exercise. Each of these factors is regulated by one or more homeostatic processes, which work together to keep life alive.
Homeostasis is caused by a natural aversion to change when things are working well, and it is maintained by a variety of regulatory systems. For the variable being regulated, all homeostatic control mechanisms include at least three interdependent components: a receptor, a control center, and an effector. The receptor is the sensing component that detects and responds to external and internal changes in the environment.
Thermoreceptors and mechanoreceptors are two types of receptors. The respiratory center and the renin-angiotensin system are two control centers. An effector is a target that is operated on to restore the normal condition. Nuclear receptors, which up-regulate or down-regulate gene expression and function in negative feedback loops, are examples of receptors at the cellular level. Controlling bile acids in the liver is one example of this.
Hence, The capacity or propensity of an organism to retain internal stability in response to external changes is defined as homeostasis. The human body maintains an average temperature of 98.6 degrees Fahrenheit as an example of homeostasis.

Thus, the answer is option E: Maintaining the internal environment in a steady state.

Note:
All organisms' metabolic activities can only occur in highly particular physical and chemical conditions. The circumstances differ depending on the organism and whether the chemical reactions occur inside the cell or in the interstitial fluid that surrounds the cells. The most well-known homeostatic mechanisms in humans and other mammals are regulators that maintain a constant composition of extracellular fluid (or "internal environment"), particularly in terms of temperature, pH, osmolality, and sodium, potassium, glucose, carbon dioxide, and oxygen concentrations.
