What is the correct pathway of development of the cerebellum? What is the correct pathway of development of the cerebellum? neur
PilotLPTM [1.2K]

Answer:

The correct answer will be option-neural tube, hindbrain, metencephalon,

Explanation:

The development of the brain during the embryogenesis takes place by the formation of a neural tube or the predecessor of the central nervous system. The neural tube arises from the ectoderm layer of the gastrula where the anterior portion of the neural tube forms the brain.

The neural tube development results in the formation of three sacs filled vesicles in which the fist vesicle forms the forebrain, second forms the midbrain and the third vesicle forms the hindbrain.

Later development process divides the hindbrain into two new portions called metencephalon and myelencephalon where the metencephalon forms the cerebellum portion of the brain.

Thus, the selected order is the correct order.

Explain the mechanisms for movement of materials across cellular membranes anatomy
trapecia [35]
There are 2 types of transport mechanisms that involve the movement of materials across the cellular membrane:

1. Passive Transport Mechanisms which is the movement of materials that does not require energy. Instead the movement relies on the permeability of the cell. Under this are three kinds of passive transport mechanisms:

a. Simple Diffusion: 
- the movement of materials from a region of higher concentration to lower concentration. No external energy is necessary for the movement. The materials supply the energy themselves. 

b. Facilitated Diffusion:
- This differs from simple diffusion because the movement is facilitated by proteins that make up the structure of the membrane. The proteins include channel proteins that allow ions and smaller molecules to cross the membrane. The other protein are the carrier proteins, which bind to materials like sugar molecules and move it across the membrane.  

c. Osmosis:
- This is the diffusion of water across the membrane. Osmosis moves water from regions where there are more water molecules of water per volume to regions where there are less water molecules per volume.  

2. Active transport on the other hand is a movement mechanism that requires energy. It uses the energy to send materials against the direction it is coming from through simple diffusion. This mechanism is used in a way to keep unwanted ions or other materials out of the cell.

When a soccer ball is in flight, what forces are acting on it?
jeka94

Answer:

Force applied on the ball when it is kicked, gravitation pull and frictional force

Explanation:

When the ball is kicked it starts accelerating, the moment when it leaves the foot acceleration starts decreasing. Here two more forces start acting on it, one is friction force caused by wind and second is tradition pull of the earth. Both these forces slow down the motion of a soccer ball and it slows down and stops.
