Answer:

b. cis test

Explanation:

A test that is used to determine if the mutation associated with a given phenotype is due to mutations in two different genes or due to different alleles of the same gene is called a complementation test.

A complementation test is also called as a cis-trans test.

If the mutations in a complementation test are located on the same position then the genes are termed as being on the cis position otherwise on the trans-position.

A cis test, that is if the genes are located on the same position serves as a control for the complementation test.

Alex

Answer: Temperature on monday morning is 319,5K

Explanation: This is an example of Gay Lussac law on gases which states that at constant volume, pressure and temperature are directly related, so if one raises the other one does as well.

The equation that follow the law is :

P1 / T1 = P2/T2 where 1 is the initial pressure and temperature and 2 is the final state.

In this equation, values have to be expressed in atm for pressure and Kelvin for temperature.

$P1 = 115 kPa .\frac{1 atm}{101,3kPa} = 1,135 atm$

$P2 = 108,75 kPa . \frac{1atm}{101,3kPa} = 1,073 atm$

The missing value is T2 (monday temperature), so we have to clear it from the equation

T2 =P2.T1/P1

Replacing values:

T2 = 1,073 atm . 338K /1,135 atm

T2 = 319,5 K
