Answer:
A heard of cattle
Explanation:
A heard of cattle is most like a community, because they stick together and are in a large group. A population, so happens to be almost exactly like a community except for a few differences
when John Travoltage rubbed his foot against the floor, he started building up negative energy, this negative energy later built up as he was rubbing his foot on the floor which then caused a reaction with the door knob, the same thing happened with the balloons, as we rubbed it on the sweater, the balloons started building up negative energy too, which then resulted in a connection with the positive energy. The dust particles most likely got a charge from moving around from different places, considering that fabrics build up the negative energy, it appears that the dust particles could have landed on a fabric which then allowed the particles to build it up and then stick to other surfaces.

Explanation:
The normal hemoglobin is made up of heme and globin. The protein, globin is in turn made up of four polypeptide chains which include two alpha and two beta chains.
The gene gene responsible for the creation of the beta globin chain is located on the short arm of chromosome eleven. It is called the HBB gene. Many mutations occur on the HBB gene and a mutation on this gene produces abnormal hemoglobin like HBS, hbc, and hbe. HBs causes sickle cell anemia.
In sickle cell anemia, there is an alteration of the genetic code, leading to the substitution of a single amino acid where glutamic acid is replaced by valine in the sixth position of the beta chain.
In the mRNA, the change converts a glutamic acid codon(GAG or GAA) to a valine codon(GUA, GUC, GUU or GUG).
Sickle cell anemia is caused by a transversion that leads to a missense mutation.
