Answer:
Motor Cortex
Explanation:
The motor cortex is principal part of the brain that involves motor (motion) functions. The motor cortex's function involves planning, deciding, and executing physical movements.
In 1870 Gustav Fritsch and Edvard Hitzig showed that electrical stimulation of the cerebral cortex of a dog produced movements involuntarily.
This experiment was a crucial event in the development of modern neuroscience.
It became an experimental evidence for cerebral cortex involvement in motor function, the electrical excitability of the cortex, the topographic representation in the brain, and the localization of function in different regions of the cerebral cortex.
Answer:
The gray tree frog is closely related to the green tree frog genetically, but they have different mating calls. This suggests that speciation occurred because of reproductive isolation.
Explanation:
It is a speciation that occurs due to a type of reproductive isolation. The song of each of these frogs has specific patterns only recognizable by members of the same species, so they are called a mechanism of reproductive isolation.
Different courtship rituals in animal species create extremely potent reproductive barriers, which keep the two frog species isolated despite They are genetically close

6. Answer;
- Faster
Explanation;
Compared to the time in Earth's history before humans appeared, rates of soil erosion are faster.
-Soil erosion is the wearing apart of topsoil. Topsoil is the top covering of soil and is the abundant fertile because it includes the several natural, nutrient-rich minerals. Every year, around 75 billion tons of soil is disintegrated from the land—a rate that is about 13–40 times as quick as the typical rate of erosion.
Additionally, some human activities associated with building structures increases the rate of erosion
7. Answer;
-Mass movement
The process responsible for moving material downslope under the influence of gravity is called mass movement.
Explanation;
-A mass movement is the geomorphic process through which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity.
-It involves the sudden movement of a block of material along a flat, inclined surface is called a rock slide or a slide.
8. Answer;
The plant roots bind the soil and regolith together.
The removal of vegetation may trigger mass movements because the plant roots bind the soil and regolith together.
Explanation;
-Vegetation removal can trigger mass wasting or mass movement as vegetation stabilizes soil. When it is removed from a slope, the slope is vulnerable to water and wind erosion.
