Question

1. Robins, like most birds in the Puget Sound area, rely on the favorable temperatures and food abundance in the spring to produce their offspring. This is important for the survival of their young because when robin chicks hatch they are naked and incapable of flying. Identify and describe three characteristics of life evident in this scenario.

1. Characteristic 1                                    : Description                                                                                                                                                                                         
2. Characteristic 2                                    : Description                                                                                                                                                                                         

C) Characteristic 3                                       : Description                                                     

2. After you a few minutes of intense physical activity, your body begins to produce and release sweat as a cooling mechanism to keep you from overheating. What characteristic of life does this example represent?

Answer 1

Answer:

Identification and description of three characteristics of life evident in this scenario-

a. Characteristic 1: Reproduction.

Description:

Robins only reproduce when favourable temperature and food is available, so reproduction completely depends on the environment.

b. Characteristic 2: Response to stimulus.

Description:

As Robins live in a cold region, where winter present in maximum time, so only spring time when temperature (i.e. stimulus) is favourable, Robins can flourish.

c. Characteristic 3: Growth and Development.

Description:

Season is important for growth and development of chicks, if Robin chicks are born in winter, as they are naked and incapable of flying, they can not grow and so died. During spring season, when adequate food is available; then only growth and development of Robins chicks can take place.

Answer:

The characteristic of life that the example represents is homeostasis.

Description:

As our body is heated during physical activity, so it has to be cooled soon. Sweating releases water and the water cools cools body surfaces; thereby helps to maintain the normal temperature, so a balance of temperature is maintained and regulated always within our body as we are endothermic organisms; this mechanism of life evident is known as homeostasis.
