For each statement below, indicate whether it is true or false.
1. all living organisms are composed of one or more cells.
2. different cell types develop in a multicellular organism because each cell has its own unique set of genes.
3. underlying similarities in biochemistry and genetics support the idea that all life evolved from a single ancestor.
4. molecules in different organisms that perform the same function are likely to have a similar structure.
5. evolutionary conservation explains the diversity of life.
6. information stored in inorganic molecules is used to direct the synthesis of cellular components.
7. cells process information stored in their dna as well as information they receive from the environment.
8. organisms are closed systems that require an input of energy in order to maintain their high level of complexity and organization.
9. homeostasis is possible because elaborate signaling networks coordinate the activities of different cells within an organism.
10. the unity of living systems arises through evolutionary change.

1. True

Organisms must have at least one cell to be considered living things. Virus are not included here.

2. False

All cells has the same DNA

3. True

Estudos recentes têm apontado que todos os seres vivos tenham evoluído de um único antepassado, no caso da teoria de Thomas Cavalier-Smith, seriam os coanoflagelados, um grupo de protistas.

4. True

DNA for example is a universal molecule, even in different organisms, it maintains its same function as that of "making" proteins needed for the cells of individuals.

5. False

The diversity of life is explained by de biodiversity, that is caused by DNA mutations, environmental pressure and the natural selection.

6. False

Informations are stored in organic molecules, like DNA

7. True

The environment can also cause our cells to process information. An example: In a sexual relationship, the environment (which is the situation) causes our body to release high levels of hormone (testosterone) that raise our heart rate and blood pressure.

8. False

Organisms are not closed systems, but open systems.

9. True

Homeostasis is the ability to maintain the internal environment in an almost constant equilibrium, regardless of changes occurring in the external environment. It is possible because of the elaborate signaling networks that exists between different cells within an organism.

10. False

Evolutionary change arises the unity of living systems

really dont know just need some points

the answer is c. it will give up it's valence electron to the other atom.
