Answer:
Biodervasity.
Explanation:
The term refers to the variety of life on earth.It demonstrates the extent of variation at different levels of species,genetic and ecosystem in a community of organisms.
It not equal in its distribution on earth;but rather varies with the type of ecosystem available and the distribution of biotic and abiotic factors in the ecosystem. For example;
It is highest in the Tropics,due to the species richness and diversity of the region. However, it varies in other ecosystem based on species diversity peculiar to parts of the region .e.g it is highest in the marine ecosystem along the coast of abundant temperature for primary producers.
The object we would need to measure force
is a spring scale
Answer:
Proten W
Explanation:
SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).
When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).
Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.
