Answer: Group 14
Explanation:
It's a carbon atom with 4 valance electrons.
Answer:
Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
Time graph plots acceleration values on the y-axis, and time values on the x-axis. In this graph, the acceleration remains constant at 2.0 m/s/s for 10 seconds. Acceleration is defined as a change in an object's velocity, so if an object is accelerating at 2 m/s/s, then every 1 second, the object will gain 2 m/s.
Answer:
The question is incomplete, no worries I got you.
Here is the complete question;
__________ reactions are used to detect antibodies for relatively large pathogens, such as bacteria. For these tests, the antigen is mixed with the test sample at various dilutions. Reaction mixes are then monitored for the formation of visible aggregates.
Explanation:
AGGLUTINATION is the reaction used.
Agglutination is the reaction in which there is the clumping of particles. A agglutination reaction is the visible clumping of the bacterial cells as an antigen reacts with its corresponding antibody. This type is often used as an initial confirmation of specific pathogens. Agglutination tests is is used to detect antibody or antigen and it involves the agglutination of bacteria, red cells, or antigen- or antibody-coated latex particles. It is therefor used for large pathogens like bacteria. In this reaction, antigens are introduced into various dilutions of antibodies in test tubes or surfaces of glass slides, visible clumping is observed which depends on the size of the antibodies, amount and acidity of the antibody molecule, time of incubation and as well as the environment of the reaction which includes optimum pH, protein concentration among others.
