Answer:
In the mentioned case, both the cells will start to perform replication of their DNA. In the case of G0, that is, the stationary phase, the mammalian cell can pass the restriction point with the supplementation of extracellular proliferation signal. While in the case of G1, which actually does not require any kind of external proliferation signal, as once the cell is in G1 phase, it is ready to go get the next phase. However, both the mammalian cells will cease or halt at G2 checkpoint.
MRNA can leave the nucleus while DNA can not
Answer:
Starting molecules not completely and quickly convert to its possible product because an activation energy barrier exist that must be overcome for conversion to product.
Explanation:
The activation energy of a chemical reaction is closely related to its rate. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier. The higher the barrier is, the fewer molecules that will have enough energy to make it over at any given moment.
Many reactions have such high activation energies that they basically don't proceed at all without an input of energy. For instance, the combustion of a fuel like propane releases energy, but the rate of reaction is effectively zero at room temperature. Once a spark has provided enough energy to get some molecules over the activation energy barrier, those molecules complete the reaction, releasing energy. The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.
Well the elements would be for weather climate is how hot or cold the atmosphere is, how many degrees above below freezing. But, for element of weather on a mountain top would be.."Humidity" is defined as how much water vapor is in the air. The state in which water is a gas is defined as "water vapor." Humidity is used to predict the chances of precipitation, dew or fog in the atmosphere. It is also Full Answer
The temperature element is the numerical measure of air in the atmosphere. Temperature is found using a thermometer and can be in Fahrenheit or Celsius. The temperature of the air has an effect on the rate of evaporation in the atmosphere, the amount of humidity and what form precipitation is in. Any state of water that falls from the sky is defined as "precipitation." This can be rain, sleet, snow or hail.
