Answer:
Environmental temperature and humidity, altitude, volume of air inspired, air currents, clothing, blood circulation through skin, and water content of the body
The R group of the proteins are side chains which are specific to each protein and which confer specific chemical properties to the proteins. The R group determines the size, polarity and the pH of the protein.
In the case of the protein where the amino acid containing a polar R group is replaced with another amino acid containing non polar R group, the TERTIARY structure of the protein might be affected. Structure will be affected if the protein is hydrophillic and the R group is hydrophobic.
Answer:
Higher the altitude, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.
Here cooler means decrease in temperature.
