Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
The first thing to do is activate
EMS. Use cool or cold water to cool the burn for 10 minutes as soon as
possible. ( Do not use ice or frozen compress.) Early cooling will minimize the
depth of injury and decrease pain. Remove jewelry near the affected area. Cover
the injury with dry, clean pad loosely
to protect it. Do not give food or drink to injured person. Keep him comfortable
until EMS arrives and takes over.
Answer:1) Carbon moves from atmosphere to hydrosphere and biosphere in the process of photosynthesis and to lithosphere by deposition of dead bodies while from hydrosphere and biosphere, carbon can be move in the process of respiration by animals.
2) During respiration process which takes place in plants in which carbondioxide is released and by eating carbon containing food by animals. By decomposing the food, carbon is releases in the form of carbondioxide.
3) Carbon can be used by the marine plants in the process of photosynthesis and during the process of diffusion, carbon is also dissolve in water bodies.
4) When the plants and animals die, the carbon which is present inside their body is buried in the soil present at the bottom of the ocean and the shells and corels of some animals also contain carbon which is soon be the part of the lithosphere when they die.
5) After the decomposition of seashell, carbondioxide is produced because shells are made up of calcium carbonate.
Explanation:
Answer: Convergent evolution occurs when two species living in different areas evolve similarities through natural selection acting on those characteristics.
