A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.
In this set of examples the answer is:
D) The lamprey does not have a vertical column
Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.
Answer:
A Starfish is Triploblastic meaning they consist of three germ layers. Hydra are diploblastic meaning they consist of only 2 germ layers.
At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
Answer:
resource partitioning
Explanation:
Based on the scenario being described within the question it can be said that this is an example of resource partitioning. This term refers to when a species divides the limited resources in order to avoid competition within it's environment. Such as the two species of mice are doing by feeding in on the same resources at different times in order to avoid competition and conflict between each other. Thus allowing them to co-exist within the same environment.
