Choose the correct afirmation about EXOGENESIS THEORY:
Life on Earth started from certain chemical elements found in the atmosphere. To organise themselves into more complex molecules. In primitive seas, the molecules formed simple unicellular organisms.
Life on Earth came about because of a comet or a meteorite that crashed into our planet. That is the result of scientific evidence found on Mars.

Choose correct options about VITAL FUNCTIONS - NUTRITION:
Anabolism is the process that creates complex molecules using simple molecules. It requires energy.
Anabolism is the process thar destroy complex molecules to create simple molecules. It releases energy.
Catabolism is the process that creates complex molecules using simple molecules. It requires energy.
Catabolism is the process thar destroy complex molecules to create simple molecules. It releases energy.
Autrophic organisms obtain inorganic materials from the environment, which they transform into organic material.
Autrophic organism take organic matter from the environment.
Heterotrophic organisms obtain inorganic materials from the environment, which they transform into organic material.
Heterotrophic organism take organic matter from the environment.
Choose correct options about VITAL FUNCTIONS - INTERACTION:
Stimuli are the changes in the environment that may provoke a response in a living things.
Stimuli are perceived by the interreceptors, which are cells or structures specialised in perceiving stimuli.
Respond to stimuli either with movements or by producing substances called glands.
Respond to stimuli either with movements or by producing substances called hormones.
Choose correct options about VITAL FUNCTIONS - REPRODUCTION:
Asexual reproduction need two or more individual to create multiple descendants which are identical.
Asexual reproduction need a single individual creates multiple descendants which are identical.
In bipartition, the cell divides into two cells, very different size.
In budding, the cell divides into two cells, very different size.
In sporulation, the cell divides its nucleus, creating many new individuals.
In bipartition, the cell divides into two cells of similar size.
In sporulation, the cell divides into two cells of similar size.
Sexual reproduction requires two individuals of opposite sex. The number of descendants is smaller than in asexual reproduction and they aren't identical.
Sexual reproduction requires two individuals of same sex. The number of descendansts is bigger than in asexual reproduction and they are identical.
