H.m.'s main problem is that he cannot form new explicit long-term memories. Explicit memory is a type of long-term memory dealing with the recall of facts and experiences. Explicit memory necessitates intentional recall of information. Declarative memory is concerned with the processing of names, dates, places, facts, events, and so on.
These are entities that are assumed to be symbolically encoded and hence may be described with words. Declarative memory, in terms of function, is optimized for rapid processing and learning. Long-term memory that does not require conscious retrieval is known as Explicit memory. Implicit memory is classified into numerous categories, including procedural memory, priming, and conditioning.

Which bonds maintain the primary structure of a protein?
a. ionic bonds
b. hydrogen bonds
c. peptide bonds
d. disulfide bonds
Peptide bonds are the type of bonds that maintain the primary structure of a protein.
Which bonds maintain the primary structure of a protein?
Peptide bonds are specific type of bonds which connect two or more amino acids together in order to maintain the primary structure of a protein. A peptide bond is also called eupeptide bond. This is a chemical bond that is formed by combining the carboxyl group of one amino acid to the carboxyl group of another amino group. We know that protein is made up of amino acids which are the building blocks of protein. Without this bond, protein molecule can not formed because amino acids are unable to combine together.
So we can conclude that Peptide bonds are the type of bonds that maintain the primary structure of a protein.

Which sequence lists organisms in the order of producer, consumer, and decomposer?
Algae, bird, earthworm is the producer, consumer, and decomposer, respectively.
Who is a decomposer?Decomposers are organisms that disintegrate rotting or dead species. Only few kingdoms, like fungi, can actually do decomposition. Decomposers are heterotrophic, which means they obtain their energy, carbon, and nutrients for growth and development from organic substrates like herbivores and predators do. Although the terms "decomposer" and "detritivore" are frequently used interchangeably, detritivores internally consume and digest dead matter, whereas decomposers directly take nutrients through external chemical and biological processes.

The belief that women were neither concerned nor troubled with sexual feelings was typical of:__________
The belief that women were neither concerned nor troubled with sexual feelings was typical of the Victorian Era.
Women in the Victorian era were suppressed and treated unequally to men. They were not even allowed to talk about undergarments to buy them and were forced to stay committed to a single man, her husband, after marriage. Women at that time were expected to stay modest and pure.
In the Victorian era, sex was not discussed openly, and ideas were confined. Dealing with inequality, women were expected to stay in a marriage with their husbands and not be involved in sex with any other man except their spouse. However, men were allowed to have extramarital affairs and women could not even ask for a divorce.
Women were not allowed to fulfill their physical desires. Instead, it was believed that sexual relations for women could not be of any concern for desires or feelings. But this was a luxury reserved for men.

For the polymerization of amino acids to form a protein, one would expect the entropy change in the reaction to be negative . this entropy change is expected because small monomers are joining to form polymer which decreases the degree of freedom.
Negative entropy change occurs when non-spontaneous change occur in the system. It means something which is more disordered will become less disordered hence energy will be required for the process.
As the monomers of the amino acids binds together to form a long polypeptide chain. It will lead to decrease in the degree of freedom of the amino acids molecule. Hence it can be called as negative entropy change.

If a solution has a pH of 7.5, what would its new pH be if the concentration
of H₂O* ions in the solution were increased by 100 times? Explain your reasoning
The correct answer is pH of 5.5 Increasing the H3O+ by 10 fold decreases the pH by 1 unit so an increase of 100 would decrease the ph by 2 units .
When the concentration of hydrogen ions in a solution increases by a factor of ten, the pH of the solution decreases by one. The acidity of a solution is thus defined as its hydrogen ion concentration [H+] expressed as the solution pH. The pH of a solution is more precisely defined as the negative log of the hydrogen ion concentration: pH=log[H+].
Most natural changes occur as a result of interactions with surrounding rock (particularly carbonate forms) and other materials. pH can also change as a result of precipitation (particularly acid rain) and wastewater or mining discharges 13. Furthermore, CO2 concentrations can affect pH levels.
