What changes were necessary in earth atmosphere to allow complex organism to evolve?
The increase in oxygen levels and the decrease in carbon dioxide levels in Earth's atmosphere were necessary changes that allowed for the evolution of complex organisms. These changes occurred as a result of photosynthetic organisms producing oxygen and sequestering carbon dioxide, creating an environment suitable for the development of multicellular life forms.

What changes were necessary in Earth and acirc and 128 and 153s atmosphere to allow complex organisms to evolve What changes were necessary in Earth and acirc and 128 and 153s atmosphere to allow comp?
The development of oxygen-producing organisms, such as cyanobacteria, played a critical role in changing Earth's atmosphere to support complex life forms. These organisms released oxygen through photosynthesis, leading to the Great Oxidation Event, which altered the composition of the atmosphere and allowed for the evolution of more complex organisms. This increase in atmospheric oxygen also provided a protective ozone layer, shielding life from harmful ultraviolet radiation.
How are ice ages are related to changes in the lithosphere hydrosphere and atmosphere?
Ice ages are related to changes in the lithosphere, hydrosphere, and atmosphere through various mechanisms. Shifts in the Earth's orbit and tilt affect the amount of solar radiation reaching the planet, leading to changes in climate. Glacial periods can cause changes in sea level, alter ocean currents, and impact the distribution of ice sheets. These changes can further influence atmospheric circulation patterns and weather systems, creating a complex feedback loop between the lithosphere, hydrosphere, and atmosphere during an ice age.
When did oxygen enter the atmosphere?
Oxygen entered the Earth's atmosphere around 2.4 billion years ago during the Great Oxidation Event. This marked a significant shift in the composition of the atmosphere and provided the necessary conditions for the evolution of complex multicellular life.
How did life on earth influence the development on earth atmosphere?
because of the first form of life that appeared on Earth and envolved. The new organism called cyanobacteria, used carbon dioxide and water to produce oxygen as a waste product. The oxygen accumulated in the atmosphere, and some of them were converted by the sun into ozone.
Why was it difficult for scientists to predict how earths climate will be affected by changes in the atmosphere?
Predicting how Earth's climate will be affected by changes in the atmosphere is difficult because the climate system is complex and influenced by numerous interacting factors, making it challenging to model accurately. Additionally, human activities can introduce unpredictable variables that further complicate predictions. The long timescales and nonlinear dynamics of the climate system also contribute to the uncertainty in predicting future climate outcomes.

What changes that occur during differentiation in a multicellular organism?
Differentiation occurs several times during the development of a multicellular organism. The organism changes from a simple zygote to a complex system of tissues and cell types.
What changes were necessary in earth's atmosphere to allow complex organisms to evolove?
During the few billion years following the appearance of cyanobacteria, oxygen became a major gas in Earth's atmosphere. The ozone layer in the stratosphere also began to develop, shielding Earth from ultraviolet rays. These major changes in the air allowed species of single-celled organisms to evolve into more complex organisms.
How does differentiation occur?
Cell Differentiation occurs numerous times during the development of a multicellular organism as the organism changes from a single zygote to a complex system of tissues and cell types.
How does an organism become more complex over time?
An organism becomes more complex over time through a process called evolution. This involves genetic changes that accumulate over generations, leading to the development of new traits and structures that increase the organism's complexity and adaptability to its environment.
What term refers to the organic growth of an organism involving the changes it undergoes from being simple to becoming more complex?
Development
What is the process of change that occurs during an organism's life producing a more complex organism?
The correct answer is GROWTH and/or DEVELOPMENT... one of the characteristics of life... Evolution is the change in a species over a long period of time.... you would not notice these changes in an organism's life. ===================================== When an organism becomes more complex during its own life, that is called growth or growth and development.
How does cell differentiation occur?
Cell differentiation occurs numerous times during the development of a multicellular organism. All organism changes from a single zygote to a complex system of tissues and cell types.
Common building block of simple and complex organisms?
Cells are the common building blocks of both simple and complex organisms. They are the basic unit of life and are responsible for carrying out all the functions necessary for an organism to survive and thrive.
What is a complex organism?
The Life that animals have.
What is the process of change that occurs during an organisms life to produce a more complex organism?
The correct answer is GROWTH and/or DEVELOPMENT... one of the characteristics of life... Evolution is the change in a species over a long period of time.... you would not notice these changes in an organism's life. ===================================== When an organism becomes more complex during its own life, that is called growth or growth and development.
Is the Golgi complex a single celled organism?
The Golgi complex is an organelle found in Eukaryotic cells. It is not an organism. Its job is to process and package macromolecules.
