Answer:
Explanation:
The switch from glutamic acid to valine in position 6 of hemoglobin (HB) forms the basis of sickle cell anemia disease pathology.
Valine is hydrophobic and it's chain is shorter than glutamic acid. The lack of the carboxylic acid and shortness of valine will result in loss of the ionic interactions formed between the glutamic acid's carboxylic group and other amino acids. A hydrophobic cavity will form in the beta sheet of HB due to the short and hydrophobic structure of valine. For these reasons, the HB molecule will be less stable and insoluble in water. The insolubility is thought to be caused by fibril formation between the valine interacting with hydrophobic pocket residues of the adjacent HB molecule. This would in turn affect binding of oxygen to HB.
2 because if you do a punnett square it shows the answer
A substance that releases hydroxyl ions in water is a base. Acids on the other hand release hydrogen ions when dissolved in water, while salts release sodium. To define acids and bases the Arrhenius definition is used by scientists---this describes what substances are produce by each type of solutions. Under the Arrhenius definition salt and water can be used to predict the result of the neutralization of an acid with a base.
In Chemistry, Bronsted-Lowry definition has superseded the Arrehenius definition.
Answer:
The algae can release harmful chemicals known as "bio-toxins" that can contaminate the water and kill the organisms living in the ecosystem
