Energy travels through a food chain/web. When an organism eats another organism, the energy from the food is passed to the eater. For example, we humans eat food to give ourselves enough calories (energy) to function properly.
Myelin sheaths are found on the outside of nerve cells. They protect the sensitive axons underneath like how insulation protects wires.
Answer:
Single stranded template to produce a double stranded product.
Explanation:
Polymerase chain reaction (PCR) is a technique in the laboratory that is used to make many copies (millions or billions) of a particular region of deoxyribonucleic acid (DNA).
The reaction utilizes primers which are short pieces of single stranded oligonucleotide templates to yield a double stranded DNA.
Two primers are used in each PCR reaction, and they are designed to identify the target region to amplified they bind to opposite strands of the template DNA at the edges of the region to be copied. The template DNA is copied and a complementary DNA is produced. The end product of the reactions a double stranded DNA that is produced from the template dna. The new DNA is the exact copy of the template dna.
