Ascientist noticed that a dark-colored peppered moth is more visible on a light-colored background than a light-colored peppered moth. he wonders, “does this difference in visibility affect the survival rate of dark moths? ” which part of the scientific method does he need to carry out next?

The scientist's next step is to form a hypothesis.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
