It produces both pollen and seeds
The answer is definetly A
B I believe would be the answer to your question above
Hello! If this takes place, then the EMT probably did not use the correct method. They should tilt the head while keeping the chin up. This prevents them from being able to gag. You would not want to change the oxygen flow because that one was probably correct for their situation. So just remove<span> the air supply and follow the head tilt-chin lift procedure.
I hope this helped!

Answer:
For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because: <u>proteins have a greater variety of three-dimensional forms than does DNA.</u>
Explanation:
Protiens have a greater variety of three dimensional forms than does the DNA
Protiens contain one or more polypeptides which are usually arranged in one of the following structures :
1)Primary structure
2) Secondary structure
3) Tertiary structure
4) Quaternary structure
These structures are maintained by Hydrogen bonding , Hydrophobic interactions , Disulphide bonds and ionic bonds )
DNA on the other hand is a double stranded molecule containing only hydrogen bonds between the nitrogenous bases and the covalent bonds within nucleotides. It is much simpler than protiens.
