Answer:
The correct options for this question are:
<span>A) Roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish.
B) Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.
F) Roaches are refusing corn syrup.</span>
<span>
</span>
<span>In this scenario (before pesticides were ever introduced to cockroaches) a certain subset of the population was genetically more likely to avoid oleic acid for whatever reason. Traits like this float throughout populations and contribute to genetic variance. When pesticides are introduced to the population, cockroaches with the previously neutral trait of oleic acid avoidance were now given a significant boost in regards to their relative fitness.</span>
Answer:
true
Explanation:
if this is true or fals its true
Answer:
A decline in the bacterial population will be observed. It is possible after a long time that these bacteria become resistant to those antibiotics
Answer:
G1 checkpoint
Explanation:
The cell cycle consists of the series of activities that occurs from the replication of DNA to the actual division of the cell in an organism's cell. However, the cell has been internally programmed to ensure that all conditions are in place/favorable before allowing progression into the next stage of the cell cycle. This internally controlled mechanism ia called CHECKPOINTS. This checkpoint occurs at three main stages of the cell cycle;
after G1 phase, G2 phase and during M phase.
In the G1 checkpoint, the cell ensures that the cell is in the right shape to proceed into the Synthesis phase of the cell cycle where it will double it's DNA. The checkpoint checks majorly for damage or change to the DNA before replicating it. If any error is found, that cell is halted and prevented from proceeding to the S-phase of the cell cycle.
This is the case in the question, the cell has been halted and prevented from entering the S-phase. Hence, its DNA is still the same as it started. However, the DNA of the cells surrounding it has been doubled as they have undergone DNA replication during S-phase.
