Expound how the mass of inert yolk influences gastrulation in amphibians, reptiles, and mammals.
Step by step
Solved in 2 steps
- Describe the gastrulation by using embryos of the sea star as an example.And describe the way in which the mass of inert yolk influences the gastrulation in bird and frog embryos.Discuss the process of gastrulation and embryonic folding?Investigate how the mass of the inert yolk affects reptiles, mammals and amphibians gastrulation
- A: Why do sea urchins have external fertilization? [Discuss the life style of the developing sea urchin embryo in the water column compared to a very different ecological niche of the adults on the ocean floor. Besides, would you want to give live birth to a sea urchin! ouch!] 2: Then why don't the parents take care of the young? [In fact the adults do in a way. After the embryo has grown large enough and metamorphosed into a young urchin they hide in the spines of the adults, living off of the scraps of food produced from the messy eating of the adults] 3: Because the urchin life involves two or more ecological niches, they are more susceptible to predation and exposure to environmental toxins. What environmental conditions, predators and toxins might they be exposed to at each stage?Describe the process of gastrulation.How many follicle cells will fit inside? Is there an abundance of yolk within the cytoplasm of the mammalian oocyte? Where will the fertilized egg develop and how will it receive its nutrients? please help
