Summary Introduction

The life is the features that differentiate the physical entities which have the biological process such as self-sustaining and signaling processes. The life exist in several forms, such as animals, fungi, protists, bacteria, archaea and plants. It is controversial to define the life and the present description is that an organisms is an open system which conserves homeostasis. It is composed of a cell and have a life cycle, experiences metabolism, mature, adjust to their environment, responds to stimuli, replicate and grow.

Answer to Problem 1TQ

A characteristics of life include metabolism, evolve as a group and cellular. Therefore, options (a), (c), and (d) are correct. 

Explanation of Solution

Justify reasons for the correct statement:

There are several characteristics are required for the life. The metabolism is one of the characteristics of life because a living group wants catabolism and anabolism and it is very essential. It supplies the energy for an organism. The cells are the basic unit of life and the cellular organization is the simple contrivance, which ascends from simple to complex one. It is also the characteristics of living organisms. The evolution is the alteration in the features of living population over time and it happens only in the living things.

Option (a) is given as “metabolism”. 

Option (c) is given as “evolve as a group”. 

Option (d) is given as “cellular”. 

Hence, options (a), (c), and (d) are correct.

Justify reasons for the incorrect statements:

Option (b) is given as “movement”. 

The movement is not the characteristics of life. All the livings are moving in some way. Hence, it is a wrong answer.

Option (e) is given as “hair or fur”. 

The fur or hair is not the characteristics of living organisms because it is not present in all the living organisms. Hence, it is a wrong answer.

Hence, options (b) and (e) are incorrect.

Conclusion

The organism is either living or dead and the features of living organisms assume it. It also helps to distinguish between the abiotic and biotic components.
