The correct option is GOLGI VESICLES.
Golgi vesicle is a transporting structure that is found in the Golgi apparatus. The principal function of Golgi vesicle is to transport packaged proteins to their different locations within the cell.
The options for this incomplete question are :
Fossils are living organisms that have wholly or partially been transformed into rock.
Lucy does not have bones with organic material necessary for carbon-14 dating.
This specimen is also far too old for C-14 dating to be accurate, as well as for any other technique but palaeomagnetic dating.
Your classmate is therefore incorrect for all of the reasons listed. (All of the above)
Answer:
The correct answer is - all of the above reasons.
Explanation:
Fossils are living life forms that have completely or mostly been changed into the rock during the process of fossilization. Lucy doesn't have bones with organic material that are essential to use the carbon 14 dating technique.
This example is additionally very old for C-14 dating to be exact, just as for some other method, however, palaeomagnetic dating can do the job of dating in this case.
Thus, the correct answer is - all of the above reasons.
Answer:
<h2>Mainly by Hydrogen bonds and the Van der Waals forces
</h2>
Explanation:
The DNA double helix (both strands of DNA) are held closs together by i) mainly hydrogen bonds between complementary bases and ii) the Van der Waals base-stacking interaction.
The hydrogen bonds between the base pairs form the double helical structure of DNA. There is no exchange or sharing of electrons in hydrogen bonds.
G always pairs with C with three hydrogen bonds and T always pairs with A with two hydrogen bonds.
