Functional classification of joints is based on the degree of mobility which is exhibited by the joints.
What is the functional classification of joints?The functional classification of joints is based upon the degree of movements or mobility that they allow. The three functional classes of joints include synarthroses, amphiarthroses, and diarthroses.
Synarthrosis is the type of joints which are immobile or allow only a limited range of mobility.
Amphiarthrosis is the joint which allows a small amount of mobility.
Diarthrosis is the joint which is the freely-movable synovial joints.

Describe how the nervous system coordinates the response of the skin to cold weather.
The sympathetic nervous system is stimulated when the skin's cold receptors are stimulated, resulting in cold thermal sensations. In the skin, arms, and legs, sympathetic stimulation causes vasoconstriction.
In a variety of physiological ways, the nervous system coordinates the skin's response to cold weather.
The following are the physiological changes that occur in response to cold temperatures:
Cold weather triggers the activation of cold receptors on the skin's surface.The sympathetic nervous system is stimulated and cold thermal sensations are brought on by these receptor stimulations.This stimulation causes vasoconstriction in the skin, arms, and legs, which reduces blood flow and makes the skin thinner, which makes superficial tissues more efficient at insulating heat.Below the thermoneutral zone, metabolic heat generated by shivering is stimulated. As a result, these physiological changes help coordinate the skin's response to cold weather.Know more about the nervous system here: https://brainly.com/question/29355295

If you change the difference in lag times of P and S waves from 00:01:50 to 00:04:00,
how does that change the distance of the earthquake to the seismic station?
The farther a seismic station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.
As the P and S waves journey out from an earthquake the P waves get regularly farther ahead of the S waves. therefore, the farther a seismic station is from the earthquake epicenter the more may be the distinction in time of arrival between the P and S wave.
The distinctive waves every travel at different speeds and therefore arrive at a seismic station at specific times. P waves tour the fastest, so they arrive first. S waves, which tour at approximately half the rate of P waves, arrive later.
P and S waves may be used to discover the epicenter of an earthquake. Since P waves are faster than S waves, the larger the appearance time distinction between the 2 waves is, the farther that location is from the epicenter.

Describe how you would carry out an experiment to test the effect of pH on protease.
Include details of control variables and the range of pH values that you would use.
To optimize the pH for the activity of the mentioned protease, perform the standard protease activity Assay with multiple buffer solutions (changing just the pH of the reaction), focusing on the pH range where the enzyme activity is high. However, keep in mind the buffer should be employed at a certain pH range.
Acetate buffers (pH 4.5-5.5), phosphate buffers (pH6-7.4), and Tris-HCl are examples (8-9). To assess pH stability, pre-incubate the enzyme in appropriate buffer solutions for a time set by you, say 2 hours, while periodically withdrawing an aliquot (maybe at 20-minute intervals) to be used as enzyme solution in the standard enzyme activity experiment. This allows you to compute the enzyme's residual activity and assess how stable it is at each pH.
What are Protease enzymes?Proteins are broken down into amino acids by protease enzymes. Albumen solution can be used to monitor the breakdown. Albumen is a protein that may be made into a solution by combining it with water. The albumen solution is hazy. The solution becomes transparent when the protein degrades.
