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.
In modern cosmology, the origin of the Universe is the instant when all the matter and energy that currently exist in the Universe emerged as a result of a great expansion.
<h3>Theories about the origin of the universe</h3>
- may change due to further investigations
<h3>in astronomer proposed a new theory about the evolution of the universe what is the next step the astronomer should take to make his theory reliable</h3>
- publish the theory in a scientific journal to let people know about it
<h3>where negatively charged particles would most likely be found in an atom</h3>
With this information, we can conclude that Electrons – Negatively charged particles located in the electrosphere; Neutrons – Neutral charged particles that, like protons, make up the nucleus of the atom. The attraction or repulsion of bodies depends on the nature of the electric charge: Bodies with charges of the same nature (or sign) – repel each other.

Answer with explanation:
a. 3 sodium ions will move from inside to outside while 2 potassium ion will mover from outside to inside. This movement occur to maintain the gradient across the membrane
b. due to ion movement the concentration of sodium ions become higher outside the cell while the concentration of potassium ion will decrease
c. Due to 3 sodium ion movement outer change became positive (+).
d. due to ion movement the concentration of sodium ions become lower inside the cell while the concentration of potassium ion will increase inside
e. this change results in decrease in charge therefore charge inside the membrane becomes negative (-). See Solved Figure Attachment.
