the sense of equilibrium maintains the stability of the head and body when they are motionless. the sense of equilibrium balances the head and the body when they are suddenly moved or rotated.
The sense of static equilibrium maintains the stability of the head and body when they are motionless. The sense of dynamic equilibrium balances the head and the body when they are suddenly moved or rotated.
Static equilibrium occurs when a body is at rest. There are two forces acting upon the body during static equilibrium, but they occur in opposite direction, and as a result the body remains static. For example, when an organism stands still in its position, it is acted upon by the force of gravity downwards and normal force upwards and thus remains in static equilibrium.
Dynamic equilibrium occurs when a process is going on. It detects the angular acceleration of the movement of head. In humans, the semicircular canals help in maintaining the dynamic equilibrium.

How and why have humans modified the ecosystem in the everglades? what have the intended and unintended consequences been?
The humans modified the ecosystem within the everglades because US Army CORPS of engineers built a levee around Lake Okeechobee, which drained about 1/3 of the Everglades.
Reason :This then cause building canals, and more levees which then create more acreage to grow crops (such as sugarcane).If the wetlands suffer, so do humans will. Humans are a part of the Everglades ecosystem because they depend on it for survival. the shortage of biodiversity caused by invasive plant species, which is in a position to spread throughout new ecosystems, means humans may lose access to good jobs, and safe water supplies for drinking and farming.
Steps for improvement :So, humans are presumably working to improve the Everglades to protect their tourism industries and water supplies. it's intended to restore, protect, and preserve the Everglades by capturing freshwater that flows unaccustomed the ocean and the gulf, and redirect it to areas that require it most for environmental restoration. because the Everglades become a more livable environment, it'll be easier for species to recover or restore along with the land.

All organisms have a natural circadian rhythm, which is one of the key distinguishing characteristics of organisms. They are present in most biochemical and molecular processes, from transcription of genes in the cell nucleus to cell cycle regulation, and are heavily involved in physiological and behavioral mechanisms. The central circadian regulatory nucleus in mammals that responds to environmental light-dark cycles is known as the suprachiasmatic nucleus (SCN) and is located in the anterior hypothalamus of the brain. A set of clock genes form a transcription-translation feedback loop at the SCN, a key mechanism of circadian rhythms. Although the SCN is essential for the generation of mammalian biological rhythms, it is not the only nucleus in which clock genes are expressed and regulated.Therefore, the correct answer is 50%.

1. From one end, a polypeptide that has been unfolded enters the cylinder.
2. When the cap is attached, the cylinder transforms into a hydrophilic environment that facilitates the folding of the polypeptide.
3. The cap is removed, releasing the correctly folded protein.
What is Chaperone (protein)?In molecular biology, molecular chaperones are proteins that aid in the conformational folding or unfolding of large proteins or macromolecular protein complexes.The common goal of all the different molecular chaperone groups is to aid in the appropriate folding of large proteins during or after synthesis as well as during partial denaturation.Chaperones are also involved in protein translocation for proteolysis. The first molecular chaperones to be discovered are assembly-type chaperones that aid in the formation of nucleosomes from folded histones and DNA.One of the primary functions of molecular chaperones is to prevent the buildup of misfolded proteins since heat stress increases the tendency for protein aggregation.The majority of chaperone proteins are hence classified as heat shock proteins.To learn more about chaperone proteins, refer to the following link:

The principle of uniformitarianism does not state that sedimentary rocks are deposited in horizontal layers. So the statement is false.
What is the principle of uniformitarianism?Grasp Earth's history requires an understanding of uniformitarianism. However, uniformitarianism was not the dominant idea before 1830. Up until that point, experts believed in catastrophism.
According to catastrophe theory, the landforms that can be seen on Earth's surface, such as mountains, were created by sudden, drastic changes, or catastrophes. Uniformitarianism's detractors may use the term "no-analog alterations" when speaking of historical climates.
According to this theory, there may not be communities or environmental factors present on Earth now that existed in the past. In the end, James Hutton and Charles Lyell's observations and research led to a challenge to the catastrophism theory. Hutton (1726–1797) was a farmer and naturalist from Scotland.
