Oak trees and alligators, for instance, have very different ways of getting food and nutrients and circulating those nutrients within their bodies.
One difference between a round worm and a flat worm is that a round worm has a no posterior end, b a mouth, c one opening to the outside environment, d cells with a cell wall, e a mouth and an anus 8.
This chapter on organismal biology is therefore split into two parts.
Organismal Biology All organisms must be able to maintain the proper balances necessary for life in a somewhat hostile world. Studies of the genetic structure of natural populations of animals and plants focus on understanding patterns of dispersal, and the nature of barriers to gene exchange; together with studies of ecology and behavior, such studies allow detailed analysis of how genotype, phenotype, and environment combine to determine evolutionary trajectories.
What is one way in which sponges are different from other animals? Regeneration is closely associated with a protection, b respirationc defense, d digestione reproduction 9. Which of the following organisms is not related to the jellyfish?
Complete the following multiple choice questions 4. Indicate which phylum is being described for each out of the Poriferam cnidarian, nematode, platyhelminthes, or annelid. Sponges cannot hunt their prey, cnidarians can. Does a clam have no body symmetrybilateral symmetry, or radial symmetry?
During the billions of years that life has existed on Earth, different organisms have developed various systems of meeting the needs of their bodies.
Most animals need a support system that is flexible enough to a with-stand temperature changes, b be digested by enzymesc allow movement, d absorb blood, e act as filters Using these methods, we explore, both within and between clades, the causes and consequences of variation in a wide suite of traits: We study the underlying molecular and environmental bases of individual variation and the consequences of phenotypic variation for fitness and organismal interactions.
Organisms connect ecology, physiology, and behavior to the fields of comparative genomics, evolutionary development, and phylogenetics. Which is a true statement about an animal that is bilaterally symmetrical?
Straight tube within a tube All animals that eat other animalsor parts of them are a carnivores b herbivores c sessile d motile e producers Smooth skinned round wormBI General Organismal Biology Study Guide 5 Sp 12 Know how the from BI at Washburn University.
Organismal Biology A ll organisms must be able to main tain the proper balances necessary for life in a somewhat hostile world.
Every organism must be able to coordinate its life processes, acquire food and oxygen, circulate that food and oxygen, eliminate waste, and reproduce.
