Intro to Biology

Question 1

What does CER stand for?

Answer 1

Claim, Evidence, Response

Question 2

What does PMC stand for?

Answer 2

Program, Metabolism, Container

Question 3

What is larger a population or community? Why?

Answer 3

A population is larger that a community because a community consist of various types of species in a given area while, a population only consist of one species in a given area.

Question 4

What is an atom?

Answer 4

An atom is the basic building block of all matter.

Question 5

What is a molecule?

Answer 5

A molecule is several atoms bonded together.

Question 6

What is an organelle?

Answer 6

An organelle is a sub-cellular structure that preforms one or more jobs in a cell.

Question 7

What is a cell?

Answer 7

A cell is the basic building block of life.

Question 8

What is a tissue?

Answer 8

A tissue is a group of similar cells in function and structure that work together as one unit.

Question 9

What is an organ?

Answer 9

A group of tissues with similar structures and functions create a united structure for a specific function.

Question 10

What is an organ system?

Answer 10

A biological system that is run by multiple organs.

Question 11

What is an organism?

Answer 11

An individual living thing that carries out the functions of life.

Question 12

What is a population?

Answer 12

A group of the same species in a geographic area.

Question 13

What is a community?

Answer 13

A group of different species all interacting is geographic area.

Question 14

What is an ecosystem?

Answer 14

A community of living and non-living things in a geographic area.

Question 15

What is a biome?

Answer 15

Two or more interacting ecosystems in a given geographic area.

Question 16

What is a biosphere?

Answer 16

All the life on the planet.

Question 17

What does the P in PMC stand for and, what is its definition.

Answer 17

The P, in PMC, stands for program. The program is the genetic code of an organism such as, DNA or RNA.

Question 18

What does the M in PMC stand for and, what is its definition.

Answer 18

The M, in PMC, stands for metabolism. The metabolism is the way organisms process energy.

Question 19

What does the C in PMC stand for and, what is its definition.

Answer 19

The C, in PMC, stands for container. This refers to keeping the area inside n organism controlled.

Question 20

What does the C in CER stand for and, what is its definition.

Answer 20

The C, in CER, stands for claim. The claim is a statement that a scientist makes when they have a theory.

Question 21

What does the E in CER stand for and, what is its definition.

Answer 21

The E, in CER, stands for evidence. The evidence supports the claim by giving logical facts from data that was collected.

Question 22

What does the R in CER stand for and, what is its definition.

Answer 22

The R, in CER, stands for reasoning. The reasoning supports both the claim and the evidence by explaining why the evidence is valid and why the evidence supports the claim itself

Question 23

What is larger atom or a molecule? What makes them smaller/larger?

Answer 23

A molecule is larger than an atom. Molecules are a group of bonded atoms, therefore, making molecules larger and more complex.

Question 24

How many different levels of an organism are there and, what are they from smallest to largest?

Answer 24

There are 13 different levels of organisms.
1. Atom
2. Molecule
3. Organelle
4. Cell
5. Tissue
6. Organ
7. Organ System
8. Organism
9. Population
10. Community
11. Ecosystem
12. Biome
13. Biosphere

Question 25

What is an example of each letter in the PMC model?

Answer 25

An example of P/Program in DNA or RNA. An example of M/Metabolism is when the human body transforms food intro usable energy. An example of C/Container is the cell membrane.

Question 26

Are virus alive? Justify your answer with evidence and reasoning. (CER)

Answer 26

Viruses are not alive even though they are biotic. One of the main characteristics of a living organism is that it can produce its source of energy. The influenza virus does not have an energy or carbon source. Sponge, however, has the energy source of the organic compounds and has a carbon source of carbohydrates. Viruses also do not have a carbon source or produce waste which the vast majority of living things do. The PMC , Program, Metabolism, and Container, model of life says that a living things, such as Amoeba, should have a container and metabolize which viruses, like the Anovirus, or influenza virus, do not do because virus don’t have a cell membrane and they do not produce their own every source or produce waste. Also, Viruses need a host to survive, and reproduce. However, all other living organisms, like a human, dog, bird, Bactria, or fish, do not need a host for any means of living. As you can see, compared to the list of living organisms, viruses don’t fit the pattern seen in the other life forms and should not be considered alive, but biotic.
