Answer:
Radiometric dating.
Explanation:
Absolute dating is the scientific process of finding out the age of an object or artifact by anthropologists.
Radiometric dating is much like absolute dating but it uses parent isotopes to measure and determine age of rock particles
Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.
Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.
The majority of the accessible drinking water on our planet comes from glaciers.
Answer:

Explanation:
In prophase 1 of meiosis there is crossing of genetic material
