1.Proteins are linear polymers built of monomer units called amino acids. The construction of a vast array of macromolecules from a limited number of monomer building blocks is a recurring theme in biochemistry. Does protein function depend on the linear sequence of amino acids? The function of a protein is directly dependent on its threedimensional structure.<span>Remarkably, proteins spontaneously fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer. Thus, </span>proteins are the embodiment of the transition from the one-dimensional world of sequences to the three-dimensional world of molecules capable of diverse activities<span>.
</span>2.Proteins contain a wide range of functional groups<span>. These functional groups include alcohols, thiols, thioethers, carboxylic acids, carboxamides, and a variety of basic groups. When combined in various sequences, this array of functional groups accounts for the broad spectrum of protein function. For instance, the chemical reactivity associated with these groups is essential to the function of </span>enzymes,<span> the proteins that catalyze specific chemical reactions in biological systems</span><span>

In your body<span>, the excretory system helps to keep salts and urea from building up to dangerous levels and becoming toxic. The kidneys are two bean-shaped organs that </span>remove these<span>toxins from your blood and produce urine to carry them from the </span>body.<span> </span>Waste<span> products must be </span>removed from the body<span>. If they are not, they will increase in concentration and may interfere with chemical reactions or damage cells. </span>Waste<span> products that must be </span>removed<span> include carbon dioxide and urea.</span>
Answer:
Alternating the compressor role every 2 minutes.
Explanation:
- High-quality CPR is essential to help the person survive after getting into cardiac arrest.
- In the high-quality CPR, two rescuers are involved and they switch positions in the CPR after every two minutes.
- By switching their positions the<em> two rescuers alternate in this high-quality CPR to give the chest compressions. </em>
- This switch is essential to reduce the fatigue faced by the rescuer.
Correct answer: A) bio-geographic isolation affects the random changes that take place within gene pools
The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other.
The mixing of there genes within the same species is separated by the geographical barrier.
The barrier allows the mating of the species in a different way as compared to the previous one.
