1.1 Levels Of Biology

Question 1

Organism

Answer 1

A term that can be applied to all forms of life. Organisms maintain an internal order that is separated from the environment.

Question 2

1. Atoms

Answer 2

An atom is the smallest unit of an element that has the chemical properties of the element. All matter is composed of atoms.

Question 3

2. Molecules are…

Answer 3

Atoms bond with each other to form molecules.

Question 4

Example of polymer.

Answer 4

Polypeptide. Formed of many molecules bonded together to be called a macromolecule.

Question 5

Examples of important macromolecules found in living organisms.

Answer 5

Carbohydrates, proteins, and numeric acids (DNA & RNA)

Question 6

3. Cells

Answer 6

Simplest unit of life. Surrounded by a membrane and contains of molecules and macromolecules

Question 7

What are unicellular organisms composed?

Answer 7

Composed of one cell.

Question 8

Multicellular is…

Answer 8

As plants and animals, contain many cells.

Question 9

4. Tissues are in multicellular organism

Answer 9

Many cells of the same type associate with each other form tissues. An example is muscle tissue.

Question 10

5. Organs are…

Answer 10

Complex multicellular organisms.

Question 11

What is the organ composed of ?

Answer 11

Two or more of types of tissues. For example, the heart is composed of several types of tissues, including muscle, nervous, and connective tissue.

Question 12

6. Organism

Answer 12

The members of the same species are closely related genetically.

Question 13

Are all living beings considered organisms?

Answer 13

Yes. As well Biologists classify organisms as belonging to a particular species, which is a related group of organisms that share a distinctive form and set of attributes in nature.

Question 14

7. Population

Answer 14

A group of organisms of the same species that occupy the same environment.

Question 15

8. Community: A biological community is…

Answer 15

An assemblage of populations of different species.

Question 16

How are biological communities determined from?

Answer 16

The types of species found in a community are determined by the environment and by the interactions of the species with each other.

Question 17

9. Ecosystems

Answer 17

Is a field of work beyond living organisms with studying their physical environment.

Question 18

Ecologists analyze ecosystems because…

Answer 18

Formed by the interactions of a community of organisms with their physical environment.

Question 19

10. Biosphere

Answer 19

Includes all of the places on the Earth where living organisms exist.

Question 20

Where is life found?

Answer 20

In the air, in bodies of water, on the land, and in the soil.

Question 21

What are the five core concepts of biology?

Answer 21

1. Evolution
   2.Structure and function
2. Information flow, exchange, and storage
3. Pathways and transformations of Energy and Matter

Question 22

Evolution

Answer 22

The diversity of life evolved over time by processes of mutation, natural selection, and genetic exchange.

Question 23

Structure and Function

Answer 23

Basic units of structure define the functions of all living things.

Question 24

Information flow, exchange, and storage

Answer 24

The growth and behavior of organisms are activated through the expression of genetic information

Question 25

Pathways and transformation of energy and matter

Answer 25

Biological systems grow and change via processes that are based on chemical transformation pathways and are governed by the laws of thermodynamics.
