Textbook Question
Chapter 53, Problem 53.1CR
Gray whales (Eschrichtius robustus) gather each winter near Baja California to give birth. How might such behavior make it easier for ecologists to estimate birth and death rates for the species?
Expert Solution & Answer
Summary Introduction
To determine: The way in which the reproductive behavior of gray whale species “Eschrichtus robustus” in California bay helps ecologists to estimate birth and death rates for the species.
Introduction: The study of change in population is termed as population dynamics. Population ecology can be defined as both, the number of individual for a particular species in an area and dynamics of the population.
Explanation of Solution
The birth rate and death rate of an organism depends upon the number of population present in a given time period. The increase in the population size leads to an increase in the number of species of the gray whale. Ecologists can estimate the birth rates by counting the number of young born per Eschrichtus robustus in a given time period. Similarly, they can estimate the death rate by observing the number of deaths in their 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?

- 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
