Lipid Bilayer.A plasma membrane is made up of Lipid Bilayers, which consists of polar phosphate heads, which are hydrophilic or water loving, and non-polar fatty acid tails, which are hydrophobic. Proteins are embedded in the membrane as well.Cell membranes are known to have holes, or selective permeable.
Answer:
In order for the sodium motive force to provide useful energy for the cell the organism must contain sodium ion gradient or potential across the membrane.
Explanation:
If the concentration of sodium is high in the inter membrane space than that of matrix then a sodium gradient is generated across the inner mitochondrial membrane.
The transport of sodium ions from inter membrane space to matrix through the sodium ion channel result in the generation of sodium motive force,that is used to provide energy to the cell.
Answer:
3rd law
Explanation:
First law of Newtons :
Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.
The second law of Newtons :
The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.
The change in the linear momentum of the object is equal to the force.
Third law of Newtons :
This law states that every action has its reaction with the same magnitude but in the opposite direction.
When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.
Therefore the answer is "third law".
Answer:
Its cells have thick, hard walls.
Explanation:
The vas deferens are a fibromuscular tube which connect to the epididymis, and is an excretory duct of the testis.
Hope I could help! :)
