It is considered that the most primitive cells were formed when:
Some protocells were able to move, reproduce and interact with others.
Some protocells were able to carry out cellular respiration and reproduce.
Some protocells were able to exchange matter and energy with the exterior, adapting to environmental changes and producing replicas of themselves.
Some protocells were able to produce different replicas of themselves and breathe.
According to endosymbiotic theory, the nucleus of eukaryotic cells:
Came about due to the DNA coiling and the edges hardening for protection.
Was formed by folding of the membrane of a prokaryotic cell.
Was formed by a different mechanism to the above three.
Was another aerobic prokaryotic cell which was swallowed and lived in symbiosis with the first.
That organisms have an internal drive, meaning they tend towards improvement and complexity, is a postulate of:
Darwinism.
Lamarckism.
Saltationism.
Actu

Which of the following contributed most to the development of Darwin's theory?
The ideas of the evolutionist A.R. Wallace, his trip around the world, and his knowledge of actualism and Lamarck's theory.
His knowledge of actualism and artificial selection, his trip around the world, and the ideas of the evolutionist A.R. Wallace.
His trip around the world, the ideas of Thomas Malthus, and his knowledge of artificial selection and actualism.
Which evolutionary theory first indicated that similar organisms are related and descend from a common ancestor?
Synthetic theory or neo-Darwinism.
Darwin's theory.
This premise does not belong to any evolutionary theory.
Lamarck's theory.
What could Darwin not explain?
The origin of variability among individuals in a population.

Among other adaptations, hominids have:
A large brain and robust teeth.
Teeth small and a large brain.
Strong teeth and a similar brain to other vertebrates.
Relatively small teeth and brain.
Is defined as the mechanism that causes new species to appear and which causes existing species to divide into two or more new species
