The ecosystem most likely regain stability the prairie dog population would begin to prey on the rattlesnakes.Hence, the correct option is D.
In a predator-prey relationship, the populations of predators and prey are interconnected and affect each other's dynamics. If the prairie dog population starts to increase, it would result in an increase in the availability of prey for rattlesnakes, leading to increased predation pressure on rattlesnakes.
As a result, the rattlesnake population may start to decrease, as they are being preyed upon by the increasing prairie dog population. This would help restore the balance in the ecosystem and regain stability by regulating the prairie dog population growth and maintaining a healthy predator-prey relationship.

which pair of terms correctly matches a cell or group of cells with its ability to differentiate into different specialized cells?
The pair of terms that correctly matches a cell or group of cells with its ability to differentiate into different specialized cells is "stem cell" and "pluripotency" or "multipotency."
Stem cells have the unique ability to differentiate into various specialized cell types in the body, and pluripotent stem cells can give rise to almost all cell types, while multipotent stem cells can differentiate into a limited number of cell types within a specific lineage.
Embryonic stem cells are a type of stem cell that are derived from the inner cell mass of a developing embryo and have the ability to differentiate into any cell type in the body. The term "pluripotent" is used to describe this ability to differentiate into all three germ layers of the developing embryo, which in turn give rise to all the different cell types in the body.
Other types of stem cells, such as adult stem cells, have a more limited ability to differentiate into different cell types, and are referred to as "multipotent" or "unipotent" depending on the extent of their differentiation potential.

Celiac disease is caused by a misdirected immune response to the protein gluten. The villi in the small intestine are damaged by the patient's own immune response. Enzyme supplements designed to digest gluten have proved to be ineffective. Hypothesize why these enzyme supplements would not be active in the stomach
Enzyme supplements designed to digest gluten are not effective in treating celiac disease because the damage caused by the patient's immune response occurs in the small intestine, not in the stomach. Gluten needs to be broken down into smaller components before it reaches the small intestine where it triggers the immune response.
Enzymes taken orally are not able to survive the acidic environment of the stomach and are therefore unable to reach the small intestine where they are needed to break down gluten. Additionally, gluten is a complex protein that is difficult to break down completely, making it challenging to design an enzyme supplement that can effectively break it down. In addition to this, the immune response in celiac disease is complex and cannot be fully addressed by simply breaking down gluten proteins. Therefore, while enzyme supplements may be helpful in some cases, they cannot be relied upon as the sole treatment for celiac disease. A strict gluten-free diet is currently the only effective treatment for this autoimmune disorder.

The statement "Only women make follicle-stimulating hormone (FSH); only men make luteinizing hormone (LH)" is false.
Both men and women produce FSH and LH. These hormones play essential roles in the reproductive system of both genders. In women, FSH stimulates the growth of ovarian follicles, while LH triggers ovulation. In men, FSH promotes sperm production, and LH stimulates testosterone production.
In women, LH and FSH work together to regulate the menstrual cycle and ovulation. FSH stimulates the growth and development of follicles in the ovaries, which contain the eggs. As the follicles mature, they produce increasing amounts of estrogen, which signals the release of LH. This surge of LH triggers ovulation, the release of the egg from the follicle. After ovulation, the remaining follicle turns into the corpus luteum, which produces progesterone to prepare the uterus for a possible pregnancy.
In men, LH and FSH are involved in the production of sperm. FSH stimulates the growth and development of the seminiferous tubules in the testes, where sperm are produced.
