Question 1:

Question 1: Properties of life and recognizing living and nonliving things

Consider the properties and characteristics of life. Choose two items (one of which is alive or has been alive and one which has never been alive). Compare and contrast their characteristics. What characteristics do they share and how are they different. Be prepared to discuss the importance of the various characteristics of living things and how their combination makes life an emergent part of the universe.

Question 2:

Thinking as a scientist, designing research

Consider the process by which scientists think through information and solve problems and how this is similar and different to how nonscientists approach the world. Consider a small problem that is solvable scientifically. Describe the process you would go through in solving that problem. Be prepared to discuss the significance of the scientific approach to the development and advancement of human knowledge.

Explanation / Answer

Ans. 1) Living things, as their name indicates, are live and energetic. They are composed up of cells; show characteristics of life, like growth, movement, reproduction, response to stimuli; they develop and need energy for daily activities. Few examples of living things around us are human beings, animals, plants, micro organisms etc. While non-living things do not exhibit any such uniqueness of life. They do not grow, respire, need energy, move, reproduce, develop or maintain homeostasis. These things are composed up of non-living objects. Some examples of non-living things are gravels, electronic gazettes, furniture, cars, trucks, train etc.

Living things has the ability move, but non-living things cannot. Living things are competent of growth, reproduction and death and they need energy to perform these tasks also.

2.) To solve a problem by scientific approach, one needs a hypotheses on which the whole research and analysis is designed. After that they have to review the literature related to their problem and study that how other researcher approach that same problem. Then they used to finalize their research methodology which includes all the necessary sample collection, survey and experimentation to gather the data. Then, all the observations are analyzed with the help of statistical software. Eventually, on the basis of statistical analysis, result and conclusion is finalized.
