I'm pretty sure 2 and 5 are right, but I'm not 100% on 1.
Have a nice day!
Both the force of windshield on the bug and that of the bug on the windshield are equal but in opposite direction.
<u>EXPLANATION: </u>
When the vehicle is moving forwards and air flows around it, and it also causes the flying bugs to hit the windshield. This impact causes a force that is imparted on both the bug and the windshield.
Thus both the bug and the windshield experience equal and opposite reactions result in Newton's Third law of motion. According to this law, it states that there will be an equal and opposite reaction for every reaction.
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.
The similarity just lies in the structure. DNA is double-stranded, however it is twisted/helical, while the ladder does not twist. However, other than that, they are quite similar. The 2 strands (5' -> 3' and 3' -> 5') of DNA serve as the 2 vertical sides of the ladder. The base pairs of DNA are what connect the two strands together. So, in terms of the ladder, think of the steps of the ladder as the base pairs. Think each step as consisting of 2 entities joining together to make 1 big step. For example, think of a step having 2 halves down the middle. 1 half would be a guanine (base) and the other half would be a cytosine (base). Guanine is connected to the 5' --> 3' strand (Left vertical side of ladder) while the Cytosine is connected to the 3' --> 5' strand (right vertical side of ladder). These two come together at one of their ends and base pair, which appears to look like the steps on a ladder.
