Hox genes - control the expression of genes that influence animal morphology (sponges are simple animals that do not have Hox genes) acoelmates - triploblastic animals without a coelom, their bodies are solid and have no cavity. Ancestors of animals... - diverged from ancient fungi, between 675 million and 800 million years ago, believed to be a suspension feeder similar to Choanoflagellates Animals are.. - -multicellular (without cell walls) -heterotropic -develop from embryonic layers ...

Traumatic Brain Injury - Answer-wound to the brain that results from a blow to the head Spinal Cord - Answer-part of the CNS encased within the vertebrae that descends from the brainstem through a canal in the backbone; provides most of the connections between the brain and the rest of the body Central Nervous System - Answer-the brain and the spinal cord, which mediate behavior Peripheral Nervous System - Answer-all of the neurons in the body outside the brain and spinal cord; provides se...

The lineage Chordata includes three subgroups which are? correct answers Two invertebrate subgroups: Urochordata, Cephalochordata; and the subgroup Vertebrata. Vertebrata are also known as? correct answers Craniata What are two subgroups of Vertebrata? correct answers Agnatha-Jawless Vertebrates Gnathostomata-Jawed Vertebrates What are the 4 anatomical features that characterize the lineage Chordata? correct answers Chordates are deuterostomes with four unique characteristics which app...

The advantage of yeast cells over bacterial cells to express human proteins is that: -CORRECT ANSWER-- yeast cells are eukaryotic and modify proteins similarly to human cells Which of the following is a change that might have facilitated the move of aquatic plants onto land? a) desire for protection from herbivory b) protection from desiccation c) ability to survive with lower [CO2] d) adaptation to seasons e) ability to grow tall -CORRECT ANSWER-- ability to survive with lower CO2 Br...

Two main divisions of the CNS The brain and the spinal cord Role of the SNS The SNS (Somatic nervous system) is composed of spinal and cranial nerves carrying information to the brain. It is responsible for movement Brainpower 0:04 / 0:15 Role of ANS The Autonomic Nervous system is composed of the parasympathetic and sympathetic nervous systems. The sympathetic controls 'fight or flight' reflex. The parasympathetic controls 'rest and digest' functions (stasis of internal...
