The two groups differ in the composition of the cell wall and the lipids in the cell membrane. 3. ... Organelles contribute to efficiency in eukaryotic cells because they concentrate the biochemicals needed for chemical reactions so that the reactions proceed more rapidly.
Answer:
Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another.
Answer:
chloroplast
Explanation:
it helps aid in the process of photosynthesis and the chlorophyll inside helps to pigment the plant and make it green
Answer:
All errors described will result in a negative result
Explanation:
The enzyme-linked immunosorbent assay (ELISA), is a test used to detect and measure antibodies, antigens and proteins in the blood. An ELISA test uses antibodies and/or antigens that are coupled to an easily-assayed enzyme, thereby this approach combines antibody specificity with the sensitivity of simple enzyme assays. ELISA test involves an antibody or antigen that reacts to form an antigen-antibody complex, where such reaction is interpreted as a positive result. The negative results are evidenced by the lack of reaction, which may be caused by some error during the chain of reactions in the ELISA test: antigen >> primary antibody (reaction) >> functional secondary antibody (reaction) >> conjugated enzyme (reaction) >> functional substrate.
