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.
I think that the correct answer to this question is D .
Frog temperature. Frogs are ectotherms, this means they gettheir heat from external sources. They are sometimes called 'cold blooded', but in fact they do not have cold blood, it is justregulated by their environment. In comparison, humans are endotherms and can maintain their body temperature at about 37°C.
Answer:
C
Explanation:
It is believed that glycolysis – the first phase of cellular respiration in eukaryotic cells- is considered an ancient biochemical process that early organisms utilized to tap the energy required for cell functions. This is because the process does not require oxygen – because early conditions on earth were anoxic before the great oxygenation event. It is after the great oxygenation event that the Krebs cycle evolved.
