Its not C. 60 years old, because I chose it and got the answer wrong. The correct answer is B. 40 years old.
b. tundra
c. arctic
d. taiga
The correct option is D.
The Taiga biome, which is also known as the coniferous forest has been described as the largest terrestrial biome because it extends across some continents of the world. The biome typically has short summers, which can be very wet and winters, which are long and can be very cold. The majority of plants in taiga biome are conifers and these plants are described as ever green because they remain green all year round.
Homeostasis is needed for an organism to survive because it keeps its internal environment stable.
It ensures that important physiological factors such as temperature, pH and nutritional levels remain within ideal limits. The stable environment allows for the proper functioning of cells and tissues, supporting metabolism as well as the creation of energy and enzyme activity.
Homeostasis enables organisms to adjust to changes in the external environment, by coordinating responses including temperature control, fluid balance, and hormone release. Many organ systems must work together to keep the body balanced. Without homeostasis, cellular processes would be disturbed and the organism's ability to adjust to environmental changes would be compromised, jeopardizing its ability to survive.

Answer:
A dilute solution has less amount of solute in the solvent. Therefore, the correct answer to the question is option B.
Explanation:
A solution is defined as a mixture of the solute and solvent. The concentration of solution depends upon the solute as well as solvent. A solution is known as to be dilute when there is less amount of solute and more amount of solvent.
A solution is said to be consulted when there is more amount of solute and less amount of solvent. Therefore, we can see that concentration of the solution is dependent upon the solute amount. In a solution a solute is present in in little less amount as compared with the solvent.
