Millions of species exist today. Based on Charles Darwin's theory of evolution, which of the following best explains how this is possible? Organisms pass on acquired traits to evolve into more advanced life forms.
Organisms are selectively bred to create new species.
New species are crossed with each other to form many different organisms.
Different genetic variations in organisms are selected in different habitats.

Which of the following statements is most likely correct about a rock belonging to the jurassic age and a rock belonging to the cambrian age? options: 1) they have identical fossils of organisms that have evolved over time. 2) both have animal fossils preserved in them due to weathering and erosion. 3) they contain different fossils because life on earth has changed through time. 4) the fossils in them were formed on the surface of earth due to exposure to sunlight.

Agene editing technology called crispr-cas9 uses cellular machinery to change the cell's genetic material. how might this technology be useful in treating diseases like cancer?

As scientists have investigated evolution from a variety of fields, they have found that some of darwin's orginal ideas were inaccurate or incomplete. t explanation provided by evolution was updated each time to reflect the new information they found. what does this suggest about the theory of evolution? it has become a stronger and clearer theory as new information is collected.
