Answer:
The average of the snails having less thick shell will disappear.
Explanation:
When a population of snails consists of both less thick and more thick snails. When an invasive species of crab enters this population.
This crab is capable of eating the snails having thin shell. Sooner or later the crabs having thin shells will disappear and the snails having thick shells will survive more.
Over a period of time there will be no snails left with thin shells only the shells having thick shells will be naturally selected and will reproduce to have a population.
The nervous system code for the difference in intensity between a gentle tap with a hammer and a hard blow with the hammer, is that the rate of neural firing and the number of neurons firing. Reflex hammer is a medical instrument used by practitioners to test deep tendon reflexes. Reflex tests are performed as part of a neurological exam, either a mini-exam done to quickly confirm integrity of the spinal cord or a more complete exam performed to diagnose the presence and location of spinal cord injury or neuromuscular disease.
White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body. They sense infections, gather at sites of infection, and destroy the pathogens.
When the body has too few neutrophils, the condition is called neutropenia. This makes it harder for the body to fight off pathogens. As a result the person is more likely to get sick from infections. In general, an adult who has fewer than 1,000 neutrophils in a microliter of blood has neutropenia.
If the neutrophil count is very low, (fewer than 500 neutrophils in a microliter of blood), it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.
