Well there are many catastrophic scenarios that we already overcome. You should consider educating yourself about the great filter. A great filter is a hypothetical barrier that each civilization can or cannot overcome. From here on things get a little complex so I won't bore you with them. But there are experts in this theory called great filter and I'm sure they can tell you a lot about.
Virus is the only organism which has only one strand
In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, i.e. observable trait. ... Such phenotypes are often expressed by the synthesis of proteins that control the organism's structure and development, or that act as enzymes catalyzing specific metabolic pathways.
Answer:
0 meters
Explanation:
When we talk about displacement, think that the think of it as the measure of the distance between the starting point of the object, from its end point.
Since we are talking about a lap around a track, it would mean that the starting point is also the end point. So if you started and end at the same point, the distance between it would be 0.
1. Our results showed that test tube B contained end products of protein digestion, meaning that the isolated enzyme has the ability to break down protein. The end products of protein digestion include small polypeptides, dipeptides, and amino acids. In general, test tube B will contain the building blocks of proteins, which are the amino acids.
2. The two test tubes were placed in a hot water bath at 37oC. This is because the enzyme studied is a human enzyme and it works best at the human body temperature, which is approximately 37oC.
Enzymes are biological catalysts, which means that they accelerate chemical reactions. As a result, an enzyme's activity is greatly affected by temperature. Every enzyme, depending on each function and origin, has a specific range of ideal temperature conditions. If the temperature rises above the maximum accepted, then the enzyme denatures and loses its structure.
3. If the enzyme studied was added in a tube containing starch instead of proteins, then nothing would happen. This is because the enzymes are highly specialized and have very specific actions. It has been proved that this enzyme's activity involves the digestion of proteins.
Starch is a polysaccharide produced by plants, this means that starch is a carbohydrate. Given that starch is not a protein, it will not be digested by the enzyme. An enzyme digesting proteins, will not have any effect on carbohydrates.
4. The smaller molecules which are the result of the digestion happening in the digestive system are absorbed by the human body. More specifically, the products of protein digestion are absorbed by the intestine and then transported into the bloodstream. From the blood, they are then absorbed by other tissues.
After they are absorbed, they are used to build muscles or other compounds which can produce energy.
