To analyze:
The correct vocabulary to replace the underline words in the given sentence.
Introduction:
A population can be defined as a group of individuals of the same species living in the same geographic area. A population has certain attributes that an individual organism does not have such as birth rate, death rate and sex ratio.

Answer to Problem 1A
Immigration.
Explanation of Solution
The density of population fluctuates due to following reasons;
Natality (B): It refers to the number of births in a given period that are added to initial density.
Mortality (D): It refers to the number of deaths that are deleted from the initial density.
Immigration (I): It refers to the number of individuals who have come into the habitat from somewhere else and added to the population.
Emigration (E): It refers to the number of individuals who left the population and migrated somewhere else
So, if N is the population density at time t, then population density at time t+1 can be shown as:
Nt+1 = Nt + ( B+I ) − ( D+E )

- The Sentinel Cell: Nature’s Answer to Cancer?arrow_forwardMolecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forward
