Pls ! a fine-grained igneous rock forms a. from magma b. as a result of quick cooling c. as a result of slow cooling d. deep within earth

The correct answer is option B, as a result of quick cooling

Due to quick cooling, the minerals do not get sufficient time to grow and thus their texture remains glassy and fine. The texture of an igneous rock depends on the rate of cooling of the magma released during volcanic eruptions. Slow cooling causes formation of large crystals while quick cooling causes formation of small crystals.

the endocrine system secretes hormones into blood and other body fluids. these chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. hormones provide feedback to the brain to affect neural processing. reproductive hormones affect the development of the nervous system.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
