Amiraneli [1.4K]

Answer:

as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

Jenny predicts that when water in a cup evaporates, the mass of the water and cup together will get smaller.
Elden [556K]

A.  Use a scale to measure the mass of a cup of water. Leave the cup out for one day and measure the mass again.

Explanation:

Jenny can predict is evaporation occurs by using a weighing scale to measure that mass of a cup of water, then he leaves the cup out for one day and he measures the mass again.

  • If the mass remains the same, then evaporation did not occur.
  • If evaporation occurs, then the mass will be lesser after the second measurement.
  • From this Jenny can infer the mass loss and made good deductions.
  • Evaporation is a phase change in which liquid turns to vapor.

NEED HELP ASAP due today
Ann [662]

Answer:

A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. Flowing water finds its way down a slope initially as small creeks. As small creeks flow downhill they shape larger streams and rivers. Rivers eventually end up flowing into the oceans with much more speed than was originally there.

Hope it helps and I did it correctly and used that words I needed to.
