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
Check Mark
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.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
