The correct answer is:
b. fat storage in their tails
Explanation;
Gila monsters deposit fat in their tail whenever they eat so they can apply it later in a shortage of food. Because their preys, such as Gambel’s quails and cottontail rabbits, have a sexual cycle that does not give the Gila monsters regular preys, they use this attribute to store energy as a form of adjustment to their preys' reproductive cycle.
Even though New Zealand has a smaller population than Australia, it has a greater population density because it covers a much smaller area. Australia’s population is approximately five times larger than New Zealand’s while the area Australia covers is approximately 30 times larger than the area New Zealand covers.
Answer:
The correct answer is option b. "The lipid bilayer is a solid at body temperature, thus protecting the cell".
Explanation:
The fluid mosaic model describes the fluid character of the cell's membrane structure as a dynamic arrangement of components that include phospholipids, proteins and carbohydrates. One of the principles of the fluid mosaic model is that the lipid bilayer that comprises the cell's membrane is solid at body temperature, thus it functions as a protective mechanism for the cell. The higher the temperature, the more fluid the cell membrane is.
Answer:
The correct answer is - The tryptophan operon shows C. negative regulation.
Explanation:
Tryptophan is an amino acid, excessively synthesized by the organism, it regulates its transcription through “trp Operon.” In this operon, the corepressor of the tryptophan binds to the repressor protein and gets activated.
This activated repressor now binds to the operator site, and prevents the binding of RNA polymerase enzyme and inhibits the protein synthesis.
