Which conclusion about the growth of new bacterial cells does the experiment support?
O Heat helps bacterial cells grow new bacterial cells faster.
New bacterial cells can only arise from preexisting bacterial cells.
The amount of available nutrients impacts the growth of new bacterial cells.
Growth of new bacterial cells depends only on the presence of nutrients.
Answers
Answer: New bacterial cells can only arise from preexisting bacterial cells.
Explanation:
Option A is wrong because when heat was applied, there was no new bacterial growth. Most likely because the heat killed the bacteria cells. Option C is also wrong as well the third trial had nutrients but no new bacteria cells grew.
Option D is wrong because in Trial 1, there were nutrients and yet no new cells were formed. This means that growth of new cells depends on more than nutrients alone.
This leaves option B as the correct answer which is proven by the lack of growth of new cells when there were no pre-existing ones in trial 3.

Answers
Answer:
An allele is a variant form of a gene.
The phenotype of the individual will always indicate with certainty the alleles of the individual
Explanation:
An allele is the alternate form of a gene example is allele A, allele a
While writing the genotype of an individual the allele is always seen, it usually written in pairs example is AA , Aa, aa, SS
The phenotype of an individual will reveal the allele such person have example is an individual with the sickle cell having allele s through the appearance of such individual one could know if such person posses the allele.

Hopetown is farther from the equator than kamina. Which location has colder air temperature and why
Answers
Answer:
Hopetown
Explanation:
The farther from the equator the colder the air temperature. This is because the equator is the point on planet Earth that receives the largest amount of solar energy, so the regions that are above this line are the warmest in the entire planet. The further away from the equator a region is established, the less solar energy it receives, which is why the poles are so cold. In this case, we can say that the Hopetown temperature is colder than the kamine temperature.
