False, the body has its adaptive defenses.
Innate defense is the first line of protection against all diseases and infections, but adaptive immunity also has the power to fight off pathogens and infections brought on by external objects.
Therefore, it is not accurate to say that our body would be totally unprotected since adaptive immunity will also manifest itself to get rid of the disease-causing substance. This is a false assertion, then.
The correct answer is that adaptive immunity will combat pathogens or foreign body infections if innate immunity fails to protect against a disease or infection because adaptive immunity also works to eradicate the disease-causing agent.

Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.
Answer:
The control group is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
