Where will you find more variation? A) between organisms of the same species, B) between organisms of different species

You will find more variation between organisms of different species (Option B). Here's why:

1. Genetic Variation: Different species have different genetic codes. This means that the DNA sequences that make up the genes in different species are different, leading to a greater degree of variation.

2. Physical Characteristics: Different species often have different physical characteristics, such as size, shape, color, etc. These differences are often more pronounced than the differences within the same species.

3. Behavior and Lifestyle: Different species often have different behaviors and lifestyles. For example, a bird species may fly and eat seeds, while a mammal species may walk and eat meat. These differences in behavior and lifestyle contribute to the overall variation between species.

4. Habitat and Environment: Different species often live in different habitats and environments, which can also contribute to the variation between species. For example, a fish species that lives in the ocean will be very different from a bird species that lives in a forest.

In contrast, organisms of the same species have a lot in common. They share the same genetic code, have similar physical characteristics, exhibit similar behaviors and lifestyles, and often live in the same or similar habitats and environments. Therefore, while there is certainly variation within a species, it is generally less than the variation between different species.
