As the pH of a solution increases, deprotonation of the acidic and basic groups on proteins occur,
so that carboxyl groups are converted to carboxylate anions (R-COOH to R-COO-) and ammonium groups are converted to amino groups (R-NH3+<span> to R-NH</span>2<span>).
In proteins the iso-electric point (pI) is defined as the pH at which a protein has no net charge.
When the pH > pI, a protein has a net negative charge and when the pH < pI, a protein has a net positive charge.
The pI varies for different proteins.</span>
Answer: Proteins are a category of macromolecules which will perform a various range of functions for the cell. they assist in metabolism by providing structural support and by acting as enzymes, carriers or as hormones. The building blocks of proteins are amino acids

Answer:
Calcium becomes an ion with a charge of 2+
Oxygen becomes an ion with a charge of -2
Explanation:
since calcium lost two electrons, it has 20protrons, but only 18 electrons. this makes calcium a positive ion with a charge of 2+
An oxygen molecule consists of two oxygen atoms that have a double bond between each other and share valence electrons. the oxygen ion is formed when the atom of oxygen gains two valence electrons. this results in an oxygen ion with a charge of -2
Answer:
2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.
Explanation:
Cloning has the potential to significantly benefit a great many people, so it should not be considered immoral or risky is refers as scientific observation.
A scientist thinks that he might find serious inconsistencies in the fossil record if he conducts an excavation in a new location is refers scientific explanation because explanation is needed for it.
The rocks present in western Africa and eastern South America formed at the same place and at the same time is scientific observation because the scientists takes the data.
Even if modern organisms are found in ancient portions of the fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.
The cloning of organisms is an exciting area of study, and more resources should be be devoted to it so it is refers as scientific explanation.
The age, type, and composition of ancient rocks in western Africa are nearly identical to the age, type, and composition of rocks in eastern South America is scientific observation which is taken by the scientist through research.
