Answer : The correct answer is B ) Hibernation .

Adaptation is a process where an animal well suited in surrounding area with time . Animals living in extremely cold habitat adapts their body which can protect them against cold . If the options are checked :

A) Clusters : Clusters is adaptation done by marine animals . They form clusters which are called as " Beds " on surfaces which provide shelter to many plants .

B) Hibernation : It is state of inactivity or winter dormancy . This is extended sleep by animals by reducing their metabolic rates and lowering of body temperature in scarcity of food in extreme cold winters. SO we can Hibernation is adapted by cold animals to survive from extreme cold.

C) Burrows : Burrows are tunnels dug by animals basically by desert animals to protect themselves from scorching heat or by animals for protection .

D) Estivation : This is similar to hibernation , state of dormancy but in very hot and dry season . Animals during summer ( hot and dry ) go to underground where the environment is cooler to protect themselves from excessive loss of water . So it is adaptation of desert animals ,

Hence Hibernation is correct adaptation for cold animals .

We apply the same amount of energy to 10.0-g samples of aluminum, iron, and silver which begin at the same temperature.
maw [93]

Answer:

Explanation:

A sound knowledge of specific heat capacity of the metals is required in this case.

The specific heat capacity of a metal is the quantity of heat required to the raise the temperature of a unit mass of it by 1°C.

It is related to quantity of heat using the expression below;

               H   =   m  c  Δt

where m is the mass

            c is the specific heat capacity

            Δt is the temperature change

let us make the specific the subject of the expression;

                     c  = \frac{H}{m x change in temperature}

we can see that there is an inverse relationship between specific heat and temperature change.

The specific heat capacity of a body is an intensive property that is unique to the metal.

   The higher the specific heat capacity, the lower the amount of temperature change in it.

Let us find the specific heat capacity of the given metals;

 Aluminium     0.897J/gK

 Iron                 0.412J/gK

 Silver               0.24J/gK

 After the heat is supplied,

      Silver >  Iron > Aluminium in terms of temperature change
