Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is <u>C.There are not enough nucleotides available to construct new DNA.</u>
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.
Answer:
decomposes and detritivores are important because without them the amount of organic waste would overflow
Explanation:
Answer:
A. Water molecules have strong intermolecular attractions.
Explanation:
Water molecules have strong intermolecular attractions due to the presence of hydrogen bond between oxygen and hydrogen atoms. This hydrogen bond is present between hydrogen of one water molecule to the oxygen of another water molecule. This hydrogen bond is weaker than covalent bond so that's why it can be broken down and water is converted into vapours form by heating.
