Answer:
4
Explanation:
According to the question, one box of jello has a mass of 250grams.
The question wants us to find how many boxes of jello would collectively weigh 1kg.
Since the units of weight here are in grams (g) and kilograms (kg), we need to convert to the same unit
1kilogram (kg) is equal to 100 grams (g).
Hence, if 1 box of jello weighs 250g
1000g of jello box will be 1000/250 in number
1000 ÷ 250 = 4.
Hence, 4 boxes of jello will weigh 1000g or 1kg.

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+.
