Answer:
C
Some vertebrates are warm blooded while others are cold blooded
Answer: B cells
Explanation:
lymphocytes produce antibodies - proteins (gamma globulins) that recognize foreign substances (antigen) and attach themselves to them. B lymphocytes (or B cells) are each programmed to make one specific antibody. When a B cell comes across its triggering antigen it gives rise to many large cells known as plasma cells. Each plasma cell is essentially a factory for producing antibody
Answer:
Charge on K is +1.
Explanation:
This gives potassium eight valence electrons in its third energy level, and flourine eight valence electrons in its second energy level. This also produces a potassium cation K+ with +1 charge and a flouride anion F- with -1 charge.
Answer:
The correct answer will be- DNA primers
Explanation:
The polymerase chain reaction is a widely used technique which replicates the DNA from a small sample of DNA in in-vitro conditions.
The mechanism of the Polymerase chain reaction is similar to the DNA replication mechanism which requires a DNA polymerase enzyme which in PCR is Taq polymerase and Primers which assists the DNA polymerase to begin the replication.
Since in the given question, the scientist added the DNA polymerase enzyme but forgot to add the single-stranded DNA called primers.
Therefore, primers are the correct answer.
