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.
I believe the answer is Axis III
In psychiatric problem, the doctor could make diagnosis in 5 different axis to make sure they assess the patient comprehensively. Axis III is dedicated for general medical condition. In this case, serious cystic acne and bad skin would be categorized as general medical condition because it was not psychological or personality disorder.
Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.
Hope that helps!
Answer:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.
Explanation:
sorry if its wrong
When atoms in a covalent bond share electrons unequally (one atoms pulls more than the other), the bond is said to be a polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion).
