ANTONII [103]

Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap between nutrition and health care available to the rich and poor?

a. 0.33

b. -0.88

c. 0.99

d. 0.0001

e. 1.3

Answer:

a. 0.33

Explanation:

Body Mass Index is defined as the measure of fat depending on the height and weight of individuals. It is being calculated as: BMI=\frac{mass_{kg}}{height_{m^2}}

The most likely heritability of body mass index(BMI) in a developing country with a large gap between nutrition and health care will be 0.33.

These is because in developing countries especially countries experiencing rapid economic growth as illustrated by the annual GDP growth rate are likely to have widely ranging lifestyles due to influences of the burgeoning economy, Therefore, there are greater chances for the rich  to have access to the basic requirements and necessities of life whereas the poor are limited with either low or no access to adequate nutrition and health care.

Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.



Hope it helped,

Ampicillin is an antibiotic that kills bacterial cells by disrupting the formation of cell walls. However, the pARA-R plasmid ha
Pani-rosa [81]

Answer: To eliminate bacteria that failed to take in the plasmid.

Explanation:

Research shows that plasmid DNA is only taken in by small percentage of bacteria in a large population.

Therefore, the need of growing transformed bacteria in the presence of ampicillin is very important. The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive.

However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.
