Compare and contrast early embryonic development in amphibians,
fish, birds, and mammals. Be sure to discuss specific features of
development such as cleavage, gastrulation, and axis formation.
Also, be sure to identify and discuss characteristics that are
unique to each category of vertebrate.

Descriptions (in random order)
--Skeleton made of bone. Various types of scales, but paired
fins that are attached to the pectoral muscles and are stiff. No
dorsal fin. First vertebrates utilize lungs for respiration.
External fertilization. Ectothermic. Have a 2 chambered heart. No

5. Explain how osmoregulation in fresh water fish differs from
osmoregulation in marine fish.
6. What do the terms stenohaline and euryhaline mean? Give
examples of animals that match these terms.
7. Describe the four stages of urine production in
vertebrates.
1. a. Salt water is denser than fresh water. Which fish would
need to have has a larger bladder? A saltwater or Freshwater
bass?
b. What is fizzing a fish?
c. A shark is a cartilaginous fish that lacks an air bladder. If
it can’t move, it will sink. Why?
d. How does the effect of water passing through a fishes gills
affect his buoyancy?
e. Is the water moving past a gill and air passing over an
airplane wing,...
Mammals, birds and insects have the ability to produce urine
that is hyperosmotic to their bodily fluid; however, insects
utilize a more simplistic mechanism. In addition to the final
product being the same, there are other stages of urine formation
in mammals and insects that is quite similar. Explain
are
birds in evolutionary specialized for reproduction? Compare them to
mammals and reptiles to make an argument for you Answer.
2 paragraphs needes. so, I need details please.
