Answer:
The correct answer is option C. "2+".
Explanation:
A common procedure to test for the presence of antigens is to perform an agglutination reaction by performing an antibody screen. In an agglutination reaction that is graded 2+ the red blood cells start to be broken and medium-sized agglutinates are formed. In this reaction no red blood cells are free, only agglutinates are seen at the bottom of the microtubes. The characteristics of the reaction herein described concur with an agglutination reaction that is graded 2+.
Answer:
b.Grow and change
c.Have a complex chemistry
d.Maintain homeostasis
Explanation:
Genes,all organisms are identified by their genomes in the big picture
Explanation:
When sandstone is overlaid by layers and layers of sediment, it becomes subject to enormous pressure and temperature beneath the layers and its grain structure begins to change. The force of compactness causes grain structure and size to reform. This is called metamophism., The sandstone becomes a new rock called quartzite. The two rocks will have different properties. Quartzite will have larger crystals and will be hard and smooth while sandstone will be coarse and soft.
