A moraine is a landform feature which is formed by the glacier retreating. The ridge of sediments that geologists found has a feature namely moraine.
<h3>What is moraine?</h3>
The materials usually soil or rocks left behind by the glaciers are called moraine.
Just like rivers that carries all sorts of debris and silt and eventually builds up to form deltas, similarly glaciers moves all sorts of dirt and boulders that assembles to form moraines.
As the geologist found a ridge of sediments and notices a glacier in the distance so this is the moraine.
Thus, the correct answer is C.

Answer:
Modern invasive species are characterized by broad environmental tolerances, which contribute to their ability to survive during both the transport and establishment phases of invasion. Studies of modern and invasive species have demonstrated that invader species regularly displace native species through higher resource efficiency or competitive ability. A striking feature of the biogeographic pattern is the differential survival of species with large geographic ranges. Species with larger geographic ranges tend, on average, to have broader ecological tolerances than those with small ranges.

The ducts empty the saliva from the submandibular salivary glands into the two sublingual carnicles.
The saliva produces in the salivary glands contains an enzyme named amylase, which is responsible for the chemical breakdown of starch. The saliva also helps to add moisture to the food and make it easier for it to pass through the ailementary canal. Further break down of starch then occurs when amylase is secreted into the small intestines.
