Introduction:
Fishes live in aquatic habitats like lakes, seas, rivers, ponds, etc. Some fishes live in complete darkness at the bottom of the deep ocean whereas others live in the freezing water of the Polar Regions and have special proteins in their blood to keep the blood from freezing. There are about 24,600 species of living fishes found.
Answer to Problem 14A
Correct answer:
The correct answer is option (A) jaws, cartilaginous skeleton, lateral line.
Explanation of Solution
Explanation/justification for the correct answer:
Option (D) jaws, cartilaginous skeleton, lateral line. Shark belongs to cartilaginous fishes. All cartilaginous fish have cartilage skeletons. The shark skeleton is also made of cartilage that gives the skeleton flexibility and the calcium carbonate that gives it strength. Shark has a strong jawline with several rows of sharp teeth. The lateral line systems of shark can detect vibrations in the water. So, the correct answer is option (D).
Explanation for incorrect answer:
Option (A) jawless, cartilaginous skeleton, lateral line. Shark has a strong jawline with several rows of sharp teeth. So, this is an incorrect option.
Option (B) jawless, cartilaginous skeleton, ray-finned. Shark has jawline and it belongs to cartilaginous fish as it has cartilage skeletons. They do not belong to ray-finned fishes as they do not have ray fins. So, this is an incorrect answer.
Option (C) jaws, bony skeleton, swim bladder. Shark has cartilaginous skeleton as its skeleton is made up of cartilage. So, this is an incorrect answer.

- "One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls?

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward
