Pepsi [2]3 years ago
3 0
The CRISPR-Cas system is widely found in bacterial and archaeal genomes as a defense mechanism against invading viruses and plasmids [1–6]. The type II CRISPR-Cas system from Streptococcus pyogenes relies on only one protein, the nuclease Cas9, and two noncoding RNAs, crRNA and tracrRNA, to target DNA [7]

Which of the following does NOT accurately state a transfer of carbon in the carbon cycle?
Doss [256]

Answer:

The point that does NOT accurately indicate a carbon transfer in the carbon cycle is that burning of wood and debris pulls carbon from the atmosphere to use as energy.

Explanation:

The carbon cycle involves the journey that carbon makes between living organisms and their surrounding environment, i.e. the entire biosphere, geosphere, hydrosphere and atmosphere, and is therefore considered a biogeochemical cycle.

In living organisms, inorganic carbon is taken up by plants to make organic molecules, which will be used by animals - which release CO₂ into the atmosphere - or dead organic matter provides carbon to the soil.

The combustion of wood and debris involves the oxidation of a combustible material -which requires oxygen from atmosphere- to then release CO₂ as a product. So it is incorrect to say that burning of wood and debris pulls carbon from the atmosphere to use as energy.

Fossils.    You would look for fossils remains, as an evidence, that of plants or animals you would expect to find at you location, and those that are out of place.  

In India, because is situated near equator, we could expect to find tropical flora fossils, not polar flora fossils in its rock.   The polar fossils support the theory that India was formed near the south pole.

If you added an electron and a neutron to Oxygen did you change the name of the atom?
horrorfan [7]
I don’t believe so, neutrons have no charge so the weight of the atom is not changed but I believe the atom would now have a negative charge
