Answer:
This is evolution.
Explanation:
Based on the system of Cladistics,some systematists are basing organism classification on the period in which they appear or evolved on earth.Therefore species of organism which evolved first are said to be the early organism, and appear higher in the level of classification,while those that evolved later are lower to these organisms in the evolutionary tree.
Simply put,Evolution refers to the progression of changes in an organism overtime.It is as a result of the ability of species of organism to withstand the selective pressure because of the presence of certain inheritable adaptive traits, compare to other organisms in the population.The organisms with these traits are naturally selected.
Therefore, the species of organism with the ability to evolved due to natural selection,are placed higher in the classification tree, while other organisms which evolved later,thus with lesser resistance to the selection pressure are placed below.
Therefore if these traits is in their DNA ,and are responsible for evolution,then classification based on evolution helps to understand the hierarchy by which different organism species appear.Hence evolution and classification are related.
The relationship between predator and prey is bepending on each other. If the prey disappear then predators would start to disappear but if there's a lot of prey them more predators but if there was more prey than predators then the prey would over populate I guess you can say so they prey,predator thing needs to be balanced
Answer:
The Environmental Protocol bans all mineral resource activities in Antarctica (other than scientific research). ... This was because unregulated exploration and mining would have caused serious environmental and political problems.
Explanation:
I think the answer will be C
When it comes to temperature regulation we can classify animals into two different groups, the endotherms, and the ectotherms.
Most mammals and birds are endotherms, which means they can alter their body temperature through their metabolic processes and be independent of the external sources of heat.
On the other sides, many reptiles are ectotherms, which means that they have to rely on external sources of heat, such as the sunlight, to maintain their body temperature
Animals also can be classified into three different groups based on the type of their skeletons. Vertebrates possess an inner skeletal system called the endoskeleton, the arthropods possess external skeleton called the exoskeleton and many soft-bodied marine animals possess hydroskeletons, bodily support systems made out of fluid-filled coelom.
