Answer:
b. the top row of a table that shows titles for the cells below
Explanation:
A header row is the first row of a given table that shows titles of the cells below it. In many cases, the header row has different styles from the other rows in the table. A header row can be found in, among others, both Microsoft's Excel and Word applications.
In the attached figure, the first row with a darker shade of background color is the header row for the table.
 
        
             
        
        
        
Answer:
Explanation:
The following code is written in Python. It continues looping and asking the user for an oligonucleotide sequence and as long as it is valid it outputs the reverse complement of the sequence. Otherwise it exits the loop
letters = {'A', 'C', 'G', 'T'}
reloop = True
while reloop:
    sequence = input("Enter oligonucleotide sequence: ")
    for x in sequence:
        if x not in letters:
            reloop = False;
            break
    if reloop == False:
        break
    newSequence = ""
    for x in sequence:
        if x == 'A':
            newSequence += 'T'
        elif x == 'T':
            newSequence += 'A'
        elif x == 'C':
            newSequence += 'G'
        elif x == 'G':
            newSequence += 'C'
    print("Reverse Complement: " + newSequence)

As data travels further over a wavelength or frequency, the radiation type goes down.
<h3>What is an electromagnetic spectrum?</h3>
An electromagnetic spectrum can be defined as a range of frequencies and wavelengths into which an electromagnetic wave is distributed into.
In Science, the electromagnetic spectrum consist of the following types of energy from highest to lowest frequency and shortest to longest wavelength:
In this context, we can infer and logically deduce that as data travels further over a wavelength or frequency within the electromagnetic spectrum, the radiation type goes down.
