Hyaluronic acid, <span>also called </span>hyaluronan.
Answer:
It is likely that the genomic sequences that were used did not enable to properly observe the evolutionary relationships among the species analyzed
Explanation:
The homology level between the genomic sequences may be too low to separate species that are phylogenetically related. In these cases, it is necessary to make a genetic analysis of the sequences that are used before the phylogenetic analysis
Answer:
Xe
Explanation:
Cs and Na are solids in room temperature while F and Xe are gases.
The number of electrons in the outermost shell of an atom will determine its reactivity. Out of the gases given Xe and F, F ( the most electronegative element) posses 5 valence shell electrons which makes it highly reactive while Xe which is a noble gas posses 8 valence shell electrons which makes it less reactive compared to many elements.
An engineering cycle is meant to assess the environmental impacts in relation to economic impacts on a product. The assessment is the whole life cycle of a product consisting of production, use phase and end of life. It's important because it helps mold the standard of living for generations to come and be sustained indefinitely. It protects against negative environmental factors but also reduces the cost of production for business', also.
