The two German Shepherds shown above were born from the same litter. One has long fur and the other has regular length fur. These dogs have different traits for their fur length because _
their DNA and RNA created different numbers of proteins that now create more fur than the previous gene.
their RNA mutated to form a new gene variation that created the variation in fur.
<
their DNA has different arrangements of nucleotides that code for the protein RNA creates
their DNA and RNA have different types of sugars that create the protein for the fur.

Explanation:

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.

cuz some people don't have enough food. that's why we need more ppl to donate food to the hungry.
