,_____ is a type of connective tissue and _____ is a type of epithelial tissue. -
ANSWERBone; lining of the digestive tract
What is the top side of a vertebrate and other bilateral organisms? - ANSWERDorsal
side
What is the bottom side of a vertebrate and other bilateral organisms? -
ANSWERVentral side
Germ layer on the outside layer of the body. Forms skin and nervous system (nerves). -
ANSWEREctoderm
The middle germ layer. Mostly muscle and bones. - ANSWERMesoderm
The inner germ layer. Forms intestines and other internal organs. - ANSWEREndoderm
Some animals only have two germ layers. Which one is missing? - ANSWERMesoderm
What type of organism do you predict would lack a mesodermal layer? -
ANSWERAquatic invertebrates such as Cnidaria (jellyfish) and Ctenophora.
How many germ levels do organ level organisms have? What are some examples of
organ level organisms? - ANSWER3 germ levels. Everything except for Cnidaria and
Porifera. Humans, birds, fish, many many more.
How many germ levels do tissue level organisms have? What are some examples of
tissue level organisms? - ANSWER2 germ levels. Cnidaria (jellyfish)
How many germ levels do cellular level organisms have? What are some examples of
cellular level organisms? - ANSWERZERO germ levels. Porifera
Fluid-filled space around internal organs. - ANSWERBody cavity
Internal body cavity lined with cells derived from the mesoderm. - ANSWERCoelom
Fluid-filled cavity is present, but only the outside is lined with mesoderm and organs are
not completely anchored. - ANSWERPseudocoelom
What are 6 advantages to having a coelom? - ANSWER1. Internal organs can be held
in place with connective tissue (mesenteries).
2. Further specialization and complexity of organs is possible.
3. Independent movement of internal organs and body wall is possible. Ex: digestive
wall can be more muscular without displacing other organs.
,4. Internal fluid can protect the internal environment and aid in movement of materials.
5. A fluid-filled cavity can function as a "hydrostatic skeleton," where the animal can
move by exerting hydraulic pressure on the fluid in the coelom.
6. Overall, coelems allowed animals to evolve more complex internal structure and to be
more flexible in their movement.
What is meant by the term "segmented body?" - ANSWERBody is divided into repeating
units.
What is an advantage of a segmented body? - ANSWERThere is more independent
movement of body parts and more specialization of body parts.
What is cephalization? - ANSWERDevelopment of a structure at one end of the body
with specialized feeding and sensory structures (head).
What are 2 advantages to cephalization? - ANSWER1. Since the head (anterior) end of
a mobile animal encounters objects in the environment first, it is advantageous if this
end gathers and processes information as fast as possible. So, many of the major
sense organs are located there, as well as the processing center (brain).
2. It is also advantageous to have feeding structures near the head because if food is
located, the animal will want to eat it as quickly as possible.
What are the four types of animal tissue? - ANSWEREpithelial
Connective
Nervous
Muscle
The tissue that lines major bodily structures. - ANSWEREpithelial tissue
What are the 3 types of epithelial tissue? - ANSWERSquamous
Cuboidal
Columnar
Tissue that provides protection and support (both physical and material) of other tissues
and organs. - ANSWERConnective Tissue
What are 4 examples of connective tissue? - ANSWER1. Adipose tissue
2. Blood
3. Bone
4. Cartilage
Tissue that coordinates many bodily functions in response to both internal and external
stimuli. - ANSWERNervous tissue
What is an example of nervous tissue? - ANSWERNeurons
, What are the 3 types of muscle tissue? - ANSWERSkeletal
Cardiac
Smooth
Name the vertebrate organ system for each life process:
Coordinate body activities - ANSWERNervous and endocrine systems
Name the vertebrate organ system for each life process:
Acquire materials and energy - ANSWERSkeletal, muscular, and digestive systems
Name the vertebrate organ system for each life process:
Maintain body shapes - ANSWERSkeletal and muscular systems
Name the vertebrate organ system for each life process:
Exchange gases - ANSWERRespiratory and cardiovascular systems
Name the vertebrate organ system for each life process:
Transport materials - ANSWERCirculatory system
Name the vertebrate organ system for each life process:
Protect against disease - ANSWERLymphatic system
Name the vertebrate organ system for each life process:
Excrete wastes - ANSWERUrinary and digestive systems
Name the vertebrate organ system for each life process:
Produce offspring - ANSWERReproductive system
What are 3 types of internal environmental parameters does an organism need to
regulate? - ANSWER1. Temperature
2. Concentration of chemicals in blood
3. pH of blood
Change in one direction initiates a response from the integrator that causes a change in
the opposite direction. - ANSWERNegative feedback loop
Response from the integrator tends to change the parameter in the same direction as
the change detected by the receptor. - ANSWERPositive feedback loop
What is the role of the circulatory system in thermoregulation? - ANSWERBlood vessels
dilate or contract
What is the role of the digestive system in thermoregulation? - ANSWERDigestion of
food creates warmth.
