DNA replicates before cell division, duplicating chromosomes. This occurs during S stage of interphase! Now each chromosome has two identical double helical models.
Answer:
Evaporation of sweat off the skin is what actually makes our skin feel cooler, rather than temperature.
Explanation:
If you are outside on a hot and humid day, you are sweating because you are hot, but the sweat does not evaporate very well. This makes you feel more hot and also makes you have that "sticky" feeling. hope this helps you :)
All the spheres on earth overlap with each other so that any changes occur in one sphere may affect the other.
<u>EXPLANATION: </u>
The four spheres of earth are Land (the lithosphere), water (hydrosphere), air (atmosphere), living things (biosphere). The living organisms receive sunlight, heat, and gases from the atmosphere and water from the hydrosphere.
All these spheres are interlinked with one other and assembles in a single location at the time of overlapping. Life would not be there on earth if all these spheres do not interact or overlap with each other.
Examples of the earth overlapping is given below;
- Birds the living organism that flies in the air.
- Water flows through the soil on land.
- Evaporation of water into the atmosphere causes rain on the land.
The answer to this question would be: False
The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
