Mollusks
Mollusks is the group of invertebrates that made up the majority of the Marine species. Their bodies tend to not divided into segments like other organisms.
Answer:
A. pH
Explanation:
Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.
However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.
The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.
The correct option is C.
Lantana is a tropical evergreen shrub which is usually cultivated as ornamental flowers. It is a plant that threatening livestock especially in Australia. The signs of lantana poisoning in livestock include: excessive skin sensitivity to sunlight, liver damage, yellow coloration of the white part of the eyes, reddening of the eyes, swelling of the ears, etc.
If the poisoning case is severe, the animal death will occur between two to four days, but generally, untreated animals usually die within one to three weeks.
