Question

You are observing and tracking the population of bobcats in a Pennsylvania state park. At the beginning of your study, there were 48 bobcats in the park. In one year, you counted 60 kittens born and noted the death of 15 bobcats. What is the per capita rate of change for this population of bobcats?

0.3125

1.25

1.5626

0.9375

The addition of the green fluorescent protein gene from a jellyfish to the genome of the zebra fish in order to produce a fluorescent green colored fish is an example of what?

genetic engineering

genetic drift

evolution

selective breeding

Cellular respiration occurs in which types of cells?

Bacterial

Animal

Plant

Protist

All of the above

Explanation / Answer

To answer the first question we have an equation to calculate the per capita rate of change/ increase of the population, that is: b - d = r. (b = birth rate, d = death rate, r = per capita rate of increase), on the other hand we have n = no of population.

In the example above we have to calcuate the per capita rate of change for the bobcat population in a Pensylvenia state park. Initial bobcat count = 48, in 1 year 60 kittens were born, and 15 bobcats were died.

per capita Birth rate b = absolute no of birth/no of population = 60/48 = 1.25, Death rate = absolute no of death/ no of population = 15/ 48 = 0.3125.

So Per capita growth rate r = b -d = 1.25- 0.3125 = 0.9375. This would be the per capita rate of change for this population of bobcats.

Second question is dealing with the answer "Selective breeding" where we can insert a specific phenotypic trait to the organism we desire to develope. So the green Fluorescent gene transfer is an example of selective breeding in case of Jellyfish to Zebrafish fish gene transfer.

Cellular respiration occurs in every form of life in any kingdom, which is known as the process in which Oxygen is required to break down the nutrients and form the energy molecule ATP for cellular respiraton process to occur. So the answer choice is "All of the above".
