Answer: A) affects genotypic expression of characters.
Explanation:
Environmental variations cause several affects on the genotypic expression of characters. Genotype is defined as the genetic that prepare in the individual so that it has production of protein which after that involving with the environmental components result in the physical characteristic named as phenotype. Therefore, environmental variation cause more affect on the genotypic expression more than itself.
Fats (lipids) are comprised of an alcohol called GLYCEROL this is alongside fatty acid tails and a phosphate group (if it is a phospholipid).
Answer:
- the discovery of the Pangaea Theory.
In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.
Answer:
the answer your looking for is number 3
The given question is incomplete.The complete question is T/F When performing column chromatography to purify a protein of interest, one needs an assay to identify which fractions that contain the protein of interest. True or False: As discussed in lecture, we use a different assay for each different protein that we purify (For instance, the assay for protein A will be different than the assay for protein B which will be different than the assay for protein C, etc).
Answer: True
Explanation:
The sample contains different types of proteins in it and when the sample into chromatography column.
Different proteins have different affinity and based on the molecular size and weight they are separated.
So, according to the question if some one wants to assay protein A, it will be different for the protein B and different for the assay of protein C. This means that assays for different proteins will be different.
Hence, the given statement is True.
