Question

the components of life section 1.1 characteristics of life no matter how different living things appear, they all have certain characteristics in common. common characteristics of all living things - all living things are made of one or more cells. - all living things have a way to reproduce. - all living things grow and develop. - all living things share a universal genetic code. - all living things must obtain material and use the energy from it. - all living things maintain a fairly stable internal environment. - all living things are able to respond to changes in their environment. - as a group, all living things change over time. in studying biology, you will take a closer look at each of these characteristics. consider the first characteristic, that all living things are made of one or more cells. cells are made of and contain various chemical compounds. to understand cells and cellular processes, it is helpful to understand some basic concepts of chemistry and biochemistry (the chemistry of living things). in this section, you will review some of these chemistry and biochemistry basics, and you will look more closely at the types of compounds that make up living things. then in section 2, you will begin to study cells. practice identify which of the following characteristics are shared by all living organisms. write a y by the characteristics that are shared by all living organisms. write an n by the characteristics that are not shared by all living organisms. 1. share a universal genetic code 2. are able to make their own food 3. are made of one or more cells 4. are made of protein 5. must use the energy from something else 6. are able to respond to changes in their environment 7. need to breathe in oxygen 8. maintain a fairly stable internal environment

Explanation:

1. Matches the listed universal characteristic of all life.
2. Only autotrophs make their own food; heterotrophs do not.
3. Matches the listed universal characteristic of all life.
4. All living things contain and are made with protein as a core biological compound.
5. Autotrophs produce their own energy source, so they do not need to use energy from something else.
6. Matches the listed universal characteristic of all life.
7. Anaerobic organisms do not require oxygen to survive.
8. Matches the listed universal characteristic of all life (homeostasis).
