It belongs to a class of molecules called the nucleic acids.
I believe it’s the first option
"Gravitational attraction" is initially responsible for the formation of the clumps of matter within this interstellar cloud.
<u>Answer:</u> Option C
<u>Explanation:</u>
About 4.6 billion years ago, the solar systems were a bunch of gases and dusts, referred to solar nebula. Gravity squeezed the material as it started to rotate, creating the sun at the middle of the fog.
The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
If the auto control is negative for both phases and antibody panel cells are 3 at immediate spin and negative at AHG, then a cold antibody may be present.
<h3>What is molecular testing?</h3>
Molecular testing refers to the strategies to find a given molecule in a sample (in this case antibodies).
The anti-human globulin (AHG) method is a test employed by blood banks to perform antiglobulin assessment.
In conclusion, if the auto control is negative for both phases and antibody panel cells are 3 at immediate spin and negative at AHG, then a cold antibody may be present.
