Witch of these is a characteristic of index fossils

Biology
1 answer:
faltersainse [42]3 years ago
8 0

Explanation:

Index fossils are fossils type fossils that are used to identify stratigraphic records and their positions. They are vey key in determining relative ages of rock sequences.

  • These fossils have a short vertical stratigraphic range.
  • Index fossils have short evolutionary history.
  • They are widely distributed in nature.
  • Examples of index fossils are trilobites and ammonites.

Which of the following holds true for energy coupling? Energy is released in an exergonic reaction./ Energy is transferred from
alekssr [168]
<span>The answer is energy is transferred from an exergonic process to an endergonic one. That is what energy coupling is. The exergonic process will release free energy and this free energy will be absorbed by the endergonic process. It can also drive the endergonic process. </span>

Over a long period, how might living things adapt to increased carbon dioxide levels and global warming?
SCORPION-xisa [38]
Yes. We could be done for if it is anthropogenic and if it is not being caused by CO2 as we are lead to believe. CO2 may not be the only anthropogenic cause (if it is a cause).

If climate change is due to weather engineering by chem trailing in conjunction with ionospheric heating, then it could cause serious illness to our species.

The use of the electro-magnetic spectum and radio waves by ionospheric heaters, could cause genetic damage as well as infertility. Whether other sources of RF/EMF also play into weather manipulation and control is unclear. Whether the use of ionospheric heaters contributes to climate change is unclear, but it intuitively seems likely. Creating a sustaining a plasma in the ionosphere may heat up more than the ionosphere and it may have an impact on the weather.

We do not know what chemicals are being used to obscure the sun, create clouds, perhaps create rain and wind, (nor why) and therefore we do not know if those could also contribute to infertility or genetic damage when they finally wash out of the sky. We do not know if the chemicals can be absorbed through the skin, or what happens to us when we breathe them, or consume them in our drinking water or in the food we eat. Higher levels of certain metals have been measured in the soil after chem trails. It is difficult to know which tests to use to test for all the chemicals which can be used.

Explanation:

The most comprehensive ecological unit of the biosphere is the biomes.

Biomes are the largest ecological unit of life.

  • They are made up of different population, communities, ecosystems of living organisms and their environment.
  • A biome is an ecosystem made up of common characteristics in the environment they are found.
  • They have internal regularities in the nature and types of fauna and flora found in such areas.
  • Examples of biomes are tundra, rainforest, desert etc
