The half life of a first order reaction is dependent on the initial concentration of reactant. (And. B)
Explanation:
Half-life: It is depends on the order of reaction, different forms for different reaction orders. It can be determined with time, rate constant of the reaction & initial concentration. The time when the concentration of the reactant is decreased to one half of the initial concentration is called half-life of a reaction.
First order reaction: The half-life of the first order reaction is independent of the initial concentration, is a constant.
Answer: B) taigas
Taigas are the coldest biome of the world. The animals and plants are adapted to survive in the harsh winter conditions. Some animals adapted to hibernate when the temperature drops and other animals have adapted to the harsh winters by changing the color of their fur that is dark brown in summers and white in winters. This adaptation help them to blend with the snow bearing environment and protect them from the eyes of predators and prey.
On the basis of the above information, B) taigas is the correct option.
