Protein that is stored in a gland and secreted to an organ to restore the body to normal conditions?

The protein which is stored into gland and maintain the body normal condition by secretion of minute quantity is called Hormone.

Explanation:

Hormones:

These are known as the chemical messengers of the human body. They basically releases from the gland and travels into blood stream and enter into tissues or organs. They work with the time slowly but they act in various ways. They act in:

The glands which produces hormones are called endocrine glands. Our body's endocrine glands are pituitary gland, thymus, pineal, adrenal glands, thyroid, testes (in men), and ovaries (in women). Even minute amount of hormones can change whole body. So, these hormones are most powerful.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
