Characteristics of Life

Choose the correct Hierarchy of Biological Organization (from largest to smallest)

• Molecules, organs, cells, organisms, tissues, ecosystem, organelles, populations, communities, and biosphere.

• Biosphere, ecosystems, communities, populations, organisms, organs, tissues, cells, organelles, and molecules

• Biosphere, communities, ecosystems, organs, organisms, populations, cells, organelles, tissues, and molecules.

• Molecules, organelles, cells, tissues, organs, organisms, populations, communities, ecosystems, and biosphere

Life is classified by:

• when life started

• what living organisms do

• what non-living organisms do

• why the universe exists

A eukaryotic cell:

(a)  

A prokaryotic cell:

(a)  

In cells, the chromosomes contain genetic material, such as

• DNA

• RNA

• FRA

• BNO

When DNA chains are made into a chain of amino acids in mRNA it is described as

• gene expression

• DNA synthesis

• protein building

• genetics creation

Genomics is

• the studying of whole sets os genes in one or more species

• the study of sets of proteins and their properties

• the entire set of proteins expressed by a given cell, tissue, or organism

• the study of sets of living organisms in the world

Proteome is

• The entire set of proteins expressed by a given cell, tissue, or ogranism

• the studying of whole sets of genes in one or more species

• the study of sets of proteins and their properties

• the study of all living organisms in the world

Proteomics is

• the study of all living organisms in the world

• the studying of whole sets of genes in one or more species

• the study of sets of proteins and their properties

• the entire set of proteins expressed by a given cell, tissue, or organism

Feedback Regulation in Biological Systems is defined as

• information about reactions to a product, a person's performance of a task, etc. which is used as a basis for improvement

• a rule or directive made and maintained by an authority

• a kind of supply-and-demand economy, where the output/product of a process regulates that very process

• information given to the learner about the learner's performance relative to learning goals or outcomes
