<h2><u>Full Question:</u></h2>
In hemoglobin, a single amino acid change at position 6 from Glu to Val has major consequences on hemoglobin structure that makes the molecule defective leading to sickle cell anemia. Predict whether the following hypothetical change would or would not have a major effect at position 6. Briefly explain (1-2 sentences). Glu to Leu Hint: Look at the structures of the R groups and consider their chemical properties
<h2><u>Answer:</u></h2>
The structure of the haemoglobin, hence the RBC won't be same as normal.
<h3><u>Explanation:</u></h3>
Both the leucine and glutamic acid are alpha amino acids which have an alpha carboxylic acid group and an alpha amino group. The variable in case of glutamic acid is propyl acid while the variable in case of leucine is isobutyl.
The glutamic acid is the normal amino acid of the 6th position of Beta chain of hemoglobin. Its an acid group, so can form bonds with another base inside the haemoglobin, or can form other hydrogen bonds. But the isobutyl group is an alkyl group. So it doesn't have that much effect in the recovering the structure, and sickle cell anemia prevails.
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.

Explanation:
Yes carbon dioxide found in each case
Answer:
identify the atoms on each side.
Count the atoms on each side.
Use coefficients to increase the atoms on each side.
Check to make sure you have the same number of each type of atom on each side.
Explanation:
The concept behind balancing chemical equations is to ensure that they comply with the law of conservation of matter. This helps to make chemical equations quantitatively meaningful.
- First, identify the atoms on each side of the expression.
- Then count these atoms.
- Assign appropriate numeric coefficient to the species.
- Then check to make sure there are equal number of each type of atoms on each side.
The subscript of the formula must not be changed in an attempt to balance a chemical equation.
