Answer:
Option-C
Explanation:
Mitophagy refers to the process which is evolutionarily conserved in the organisms to remove the dysfunctional mitochondria in the cell.
The mitochondrial is degraded by the digestive organelles by engulfing the mitochondria.
The mitochondria are engulfed by the lysosome and then phagosome is formed which is double membrane structure.
This phagosome matures into the autophagosome and now has the mitochondria engulfed.
Since the mitochondria contain toe layer and during mitophagy engulfed by the phagosome, therefore, there is a total of four-layer.These four layers separate the matric of the mitochondria with the cytosol.
Thus, Option-C is the correct answer.
Answer: Bundles of axons in the central nervous system are called a "tract"
Explanation:
Axons(nerve fiber) consist of long slender projection of neurons or nerve cells that conduct and transmit impulses away from the neuron or nerve cell body. Axons are surrounded by endoneurium layer which contain protein fluid that surround each axon.
Bundles of axon in the CNS is known as tract. We have ascending tracts and descending tracts. The ascending tracts function are to conduct and carry impulses along the spinal cord to the brain while the descending tracts transmit and carry the impulses from the brain to lower regions (downward) of the body. Tracts are identified by their origin (where the bundle start) and also the end/termination of axon bundle.
The largest tracts are fasciculi gracilis and cuneatus which are known as ascending tracts.
Answer:
Facilitated diffusion involves transport protein
Explanation:
Answer:
Answer: Water rise to tall trees by suction pull during day it is low but during night time it is fast. during night time transpiration is fast and transpiration create a pressure also called transpirational pull which cause root water to move at leaves.
Explanation:
Lactose because it is a sugar made up of galactose and glucose.
