Answer:

Explanation:

The following code is written in Python, the function creates various nested loops to loop through each individual string comparing letter by letter in order to find the longest common substring. Finally, returning the substring itself.

def shared_motif(dna_list):

substr = ''

if len(dna_list) > 1 and len(dna_list[0]) > 0:

for x in range(len(dna_list[0])):

for i in range(len(dna_list[0]) - x + 1):

if i > len(substr) and all(dna_list[0][x:x + i] in y for y in dna_list):

substr = dna_list[0][x:x + i]

return substr

arr = ["GATTACA", "TAGACCA", "ATACA"]

stems = shared_motif(arr)

print(stems)

This program finds the sum and average of three numbers. What are the proper codes for Lines a and b?

Gennadij [26K]

Answer:

The Proper codes in Line a and Line b is given below

average=Sum/3

print (" Average is = ", average)

Explanation:

In the given question it calculated the sum but the program does not calculate the average of the 3 numbers.The average of the 3 number is calculated by using average=Sum/3 statement so we add this code in Line a then After that print the value of average by using the print function so we add this code in Line b.

Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 3 8 the output is

Misha Larkins [42]

Answer:

The program to this question can be given as:

Program:

def swap_values(user_val1, user_val2): #define function

return (user_val2, user_val1) #return values

if __name__ == '__main__': #define constructor.

n1 = int(input('Enter first number :')) #input value form user

n2 = int(input('Enter second number :')) #input value form user

(n1,n2) = swap_values(n1,n2) #hold function values.

print(n1) #print values

print(n2) #print values

Output:

Enter first number :3

Enter second number :8

Explanation:

The explanation of the above python program can be given as:

In the python program we define a function that is "swap_values". This function takes two integer values that is "user_val1 and user_val2" as a parameters and returns variable values that is "user_val2 and user_val1".
Then we use a constructor in this we define two variable that is "n1 and n2" these variable are use to take user-input from the user and pass the value into the function.
To hold the value of the function we use n1 and n2 variable and print these variable value.

Skylar is viewing her personal and business calendar in a side-by-side fashion, but she would like to view a single calendar tha

pogonyaev

Answer:

The solution for the current situation in which Skylar is viewing her personal and business calendar in a side-by-side fashion, but she would like to view a single calendar that has appointments and meetings from both personal and business. is:

Configure the Overlay option.

Explanation:

The reasons behind this answer are that in the first place, creating another calendar is too much work. In the second place, the share of the calendars is not going to help her because that would only allow someone else to watch her calendars. However, using the overlay option will allow her to mix them and create one calendar with all her information.

A 1.17 g sample of an alkane hydrocarbon gas occupies a volume of 674 mL at 28°C and 741 mmHg. Alkanes are known to have the gen

Nina [5.8K]

Answer:

C3H8

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Mass of alkane = 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

Gas constant (R) = 0.08206 atm.L/Kmol

Step 2:

Conversion to appropriate unit.

For Volume:

1000mL = 1L

Therefore, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature (Kelvin) = Temperature (celsius) + 273

Temperature (celsius) = 28°C

Temperature (Kelvin) = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

Therefore, 741 mmHg = 741/760 = 0.975atm

Step 3:

Determination of the number of mole of the alkane..

The number of mole of the alkane can be obtained by using the ideal gas equation. This is illustrated below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

Gas constant (R) = 0.08206 atm.L/Kmol

Number of mole (n) =?

PV = nRT

n = PV /RT

n = (0.975 x 0.674)/(0.08206x301)

n = 0.0266 mole

Step 4:

Determination of the molar mass of the alkane.

Mass of alkane = 1.17g

Number of mole of the alkane = 0.0266mole

Molar Mass of the alkane =?

Number of mole = Mass/Molar Mass

Molar Mass = Mass/number of mole

Molar Mass of the alkane = 1.17/0.0266 = 44g/mol

Step 5:

Determination of the molecular formula of the alkane.

This is illustrated below:

The general formula for the alkane is CnH2n+2

To obtain the molecular formula for the alkane we shall assume n = 1, 2, 3 or more till we arrive at molar Mass of 44.

When n = 1

CnH2n+2 = CH4 = 12 + (4x1) = 16g/mol

When n = 2

CnH2n+2 = C2H6 = (12x2) + (6x1) = 30g/mol

When n = 3

CnH2n+2 = C3H8 = (12x3) + (8x1) = 44g/mol

We can see that when n is 3, the molar mass is 44g/mol.

Therefore, the molecular formula for the alkane is C3H8.

A hidden backlog contains the projects that the IT department is not aware of because of low feasibility.

Finger [1]

Answer: True

Explanation:

Yes, the given statement is true that the due to the very low feasibility the IT (Information technology) department are not aware of the hidden backlog that basically contain projects.

The feasibility is the main factor in the IT department as it helps to study whole objective of the project and then also uncover all the strength and weakness of the project so that we can easily go through the details to make the project more efficient and reliable.
