To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.
In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.
- In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content. According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
- In basic solutions, the concentration of OH- ions is higher than that of H3O + ions. If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution. Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.
Answer:
Option (B).
Explanation:
Peyer's patches are the small masses of aggregated small lymphatic tissues and provide immunity to an organism. Peyer patches are discovered by the scientiest Johannan Cornard Peyer.
Peyer's patches are located in the ileum region of small intestine. These patches control the growth of harmful bacteria and regulates the growth of intestine bacteria. T
Thus, the correct answer is option (B).
Answer:
An organ is a group of tissues that work together to perform a specific function. In the case of your heart, this function is pumping blood throughout your body. Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle.
Explanation:
If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.
Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.
The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.
