Answer No 1:
During the interphase, the genetic material is copied so that each daughter cell can receive equal and right amount of genetic material. The right amount of the genetic material is a crucial step for every daughter cell to survive.
Answer No 2:
Embryonic stem cells have the ability to convert into any type of cell type. Specialized cell types can make specialized cells. Scientists are working on producing stem cells which can cure various diseases like paralysis or brain damaged cell.
Answer No 3:
By the process of meiosis, the number of chromosomes is reduced to half in the sex cells. When an egg cells and the sperm cell unite in the process of fertilization, the number of chromosomes become diploid again. Hence, the number of chromosomes gets maintained in the embryo in this way.
Answer:
Axons with high diameter, and myelinated will conduct action potential faster.
Axons with low diameter but myelinated will be relatively slow in the speed of action potential transmission
Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.
Axons with low diameter, and unmyelinated will conduct action potential slowly .
Explanation:
Diameter of Axon affects conduction speed of Action Potential; the thick axons with high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.
Myelinated neuron transmits action potential faster because of jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1
.Conversely, unmyelinated neurone conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
The temperature of the cars seats and the thermal energy of the seats INCREASES.
Sunlight can trasfer heat energy by radiation, when heat is transfered, the seats gain heat and the temperature rises due to the increase of kinetic energy of the molecules, the molecules move faster. As the temperature rises, the thermal energy is increased too because kinetic energy (and potential, but this is about the state of matter) of the molecules makes up the thermal energy of an object.
