castortr0y [4]3 years ago
5 0

The isopropanol will extract the DNA from the strawberries.

Explanation:

Strawberries help in DNA extraction as it has enzymes and pulverizes easily which breaks the cell wall and has large number of DNA in it. The isopropanol helps in precipitating the DNA.

In an experiment of DNA isolation, a squashed and refrigerated strawberry was added in a isopropanol solution after filtering it. It can be seen DNAs are starting to isolate from the strawberry extract in the form of fluffy bubbles.

Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap be
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.
