To determine:
Whether the declination in amphibian population affects the human.
Introduction:
Amphibians are an unavoidable part of the food web. Amphibians are the connecting link between aquatic and terrestrial animals and keep the balance between both food chains. Larva of amphibians feed upon the algae and other aquatic plants and adult amphibians feed upon the insects and mosquitoes.
To explain
The reason of declination in amphibian population
Introduction:
The declination of amphibians is high and it is affecting the human and environment badly. There are many factors which are causing the declination in a population of amphibians. Many environmental effects affect the existence of amphibians, as well as there are many men created reasons for the disappearance of the amphibian population.

- "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
