Question

living and non - living things. identify which of the following characteristics are shared by all living organisms. match a y by the characteristics that are shared by all living organisms. match an n by the characteristics that are not shared by all living organisms. share a universal genetic code are able to make their own food are made of one or more cells must use the energy from something else are able to respond to changes in their environment need to breathe in oxygen maintain a fairly stable internal environment are made of protein

Explanation:

1. All living organisms share a universal genetic code, which is the basis for heredity and protein - synthesis. So it is 'Y'.
2. Only plants (autotrophs) and some bacteria can make their own food through photosynthesis or chemosynthesis. Many living organisms (heterotrophs) cannot. So it is 'N'.
3. All living things are made of one or more cells, which are the basic units of life. So it is 'Y'.
4. All living organisms need energy, and most obtain it from other sources (heterotrophs), while some can produce their own (autotrophs). So it is 'Y'.
5. All living organisms can respond to stimuli in their environment, a characteristic known as irritability. So it is 'Y'.
6. Not all living organisms need to breathe in oxygen. Some are anaerobic and can live without it. So it is 'N'.
7. All living organisms maintain a relatively stable internal environment, a process called homeostasis. So it is 'Y'.
8. All living organisms are made of protein, which is involved in many biological functions. So it is 'Y'.

Answer:

1. share a universal genetic code: Y
2. are able to make their own food: N
3. are made of one or more cells: Y
4. must use the energy from something else: Y
5. are able to respond to changes in their environment: Y
6. need to breathe in oxygen: N
7. maintain a fairly stable internal environment: Y
8. are made of protein: Y
