<span>B. Rocks go through many stages during their formation</span><span>
Sedimentary rocks together with the igneous rocks and the metamorphic rocks are the three main types of rocks that existed on earth. It is formed or made accordingly into four major ways. First, it is formed by depositing weathered remains of "clastic sedimentary rocks" or other rocks. Second, is through accumulation and the consolidation of sediments, thirdly is by depositing the results of biogenic activity and lastly it is formed through precipitation from solution. Limestone, shale, chalk clay and others are best examples of sedimentary rocks. </span>
The correct answer is 2. By a feedback loop.
Hormone levels in the body is regulated by negative feedback mechanism. In this mechanism, a stimulus stimulates the release of a substances. After the effect of that substance its further release is inhibited. This can be understood by an example, the anterior pituitary gland stimulate the thyroid gland to release thyroxin and on increasing the thyroxin in the blood, feedback the hypothalamus and anterior pituitary to inhibit further release of thyroxin from thyroid gland.
Of the three salivary glands (Sublingual, submandibular and parotid glands), the parotid is the largest. They are all paired. The parotids are located on either side of the mandibular ramus. It produces ptyalin, an alpha-amylase, and is responsible for 20% of the total saliva content produced into the mouth.
