The correct answer is: b. corticospinal pathway
The corticospinal pathway is a motor pathway that starts at the cerebral cortex and terminates on lower motor neurons and interneurons in the spinal cord. Its function is to control the movements of the limbs, directly and voluntary.
Answer:
carbon, oxygen, and hydrogen atoms.
Explanation:
Answer:
Explanation:
Mitochondria is a double membrane bound organelle that is located in most eukaryotic organisms and it has a number of different shapes.
A mitochondrion has a outer and inner membranes made up of phospholipid bilayers and proteins which have different properties. Because of the double membraned organization, mitochondria have five distinct parts:
Outer mitochondrial membrane
Intermembrane space which is the space between the outer and inner membranes
Inner mitochondrial membrane,
the cristae space which is formed by the folding in of the inner membrane and
matrix which is the space within the inner membrane.
Mitochondria has a complex structure that allows for all the activities carried out by it this includes,Energy conversion, Pyruvate and the citric acid cycle, NADH and FADH2 which are the electron transport chain, Heat production and Storage of calcium.
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
