Heirchey of life

Framework for understanding that living things from the smallest cell to the largest biosphere are organized into a system made of interconnected parts that work together

Response to stimuli

Interaction with environment

Reproduction

Produce offspring / new individual with similar characteristics

growth in development

Inherit knowledge through genes

Growth

Change in size

Development

Change in form

Adaptation

Needed for survival / life

Energy processing

coverting chemical energy to mechanical energy (Ex. Birds eat food to be able to fly)

Regulation

Maintaining internal condition

Homeostasis

Control of ones body temperature despite external changes

Order

Characteristic of God

“Is it alive if it uses energy”

Using energy alone does not mean something is alive. This can be seen through the creation of mechanisms such as cars

“If something grows but cannot reproduce is it alive”

Yes

• Growth is a sign of life.

• Reproduction is a characteristic of life, but an individual organism does not need to reproduce to be alive.

Theory of evolution

• made by charles darwin

• How all kinds of organisms came into existence, why organisms look the way they do and explains that organisms living on earth today are modified descendants of their ancestors

Genetic Variation

• causes theory of evolutuon

• Difference in dna sequence and gene makeup among individuals within a population or spiece

Signs of Sexual reproduction

Example of genetic variation

• Difference in eye color, blood type or height among humans

Mutation

Example of genetic variation

• random change in genes

• Ex. Different leaf shapes

Theory of evolution by natural selection

Organisms with traits better suited to their enviroment are more likely to survive and reproduce, passing those advantagous traits to their offspring

DNA

• universal molecule of inheritancr

• Sane structures, differ in dna sequence for all species

Evolution

• culmative change in population of organisms over time

Antibiotic

• Powerful medicine to kill bacteria

• Why is it created if it it kills bacteria?: indicative that bacteria cannot be permanently killed due to mutation

Natural selection

• created by charles darwij

• “Those with better traits learn to adapt while those who dont die”

Competition

• number of population have the capacitt to produce more offspring more than the capacity to provide of the environment

Theory of Acquired Inheritance

• Created by Jean Bapatiste de Lamark

• “Physical desire determines the development of the organism’s body and increase in the size of the organ“

• Can be passed onto the next

“It is not the strongest nor the most intelligent that survives but the most responsive to change”

Quote by charles darwin

Fossil record

• embedded in centenary rock

• “The deeper it is buried the older it is”

• Shows similarities in species and proves variation

Geographic distribution

• different environments causes organisms to adapt differently

Variation

• difference in the same species

Gregor Mendel

• made gentic inheritance (explains genes and dna)

Explained by Gregor and Charles’ Theory

Variation

Comparative Anatomy

• study of similarities / differences in the anatomy of different species to understand their evolutionary relationships

Homologous structure

Similarities in structure but different functions

Common traits in embryo

• neck

Gene

specific segment of DNA

Stimulus

External or internal occurrence that triggers a response or reaction from an organism

Types of stimulus

Behavioral & psychological

Physiological

Hormones released in response to stress or cells stopping bleeding

Behavioral

Action

Tropism

Growth or movement of a biological organism (typically a plant) to a specific external enviroment stimulus the direction of the response is dependent on the direction of the stimulus

Response stimulus of animals

Sense orgasms and nerve cells, nervous systems

Response stimulus of plants

Sensitive cells and hromones that guide their responses

Difference of response stimulus

• speed of response

• Purpose of survival

Similarities

• Both respond to stimulus

• Adaptation

• Chemical signals

Needs of living organisms for survival

• basic needs

Systems that help them survive
