a sinoatrial node is the main pacemaker that begins each heartbeat located in the junctions of superior vena cava and the right atrium. It signals from the node that spread through the atria and determines the heart rates.
In DNA, thymine binds to adenine, and cytosine binds to guanine. This means that there is an equal amount of thymine and adenine, and there is an equal amount of cytosine and guanine.
If there is 15% thymine, there should be 15% adenine.
Note that in real life, the percentage of bases won't be 100% equal.
Answer:
It helps them survive
Explanation:
Mimicry is when animals have forms and coloration that makes them blend in with their environment, which helps them to escape from their predators or approach their prey undetected and thus mimicry helps organisms survive. An example is the stick insect. They look like real sticks in shape and color and even move in a way that resembles a stick movement by the wind. This way they may escape the sharp vision of many insectivorous birds.
