Answer:

Mitosis

Explanation:

Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.

Alborosie
<span>Some of the things that would make the experiment invalid would be, if there was a variation in the behavior of the class with respect to food - for example, if some people ate their breakfast earlier than the others. This then would mean that some students would have already digested their breakfast during the morning classes and the others would still be digesting. </span>

A constant rate of increase (rmax) for a population produces a growth graph that is J-shaped rather than a straight line. Why?
Alexus [3.1K]

Answer:

Explanation:

The line graph illustrates the temperatures in London, New York and Sydney on monthly average and the table introduces the information about the annual hours of sunshine for these cities. The overall view is that London is always exceeded by the rest in both the temperature and the number of sunshine hours.

To specify, the line graph shows that in New York, the average temperature goes up slightly from 4.5 degree in January to 8 degree in March, before a more significant increase to the highest of 30 degree in July, followed by a drop to 5 degree in December. Similarly, in London, after climbing gradually from the lowest point of 9 degree to the highest of 23 degree in July, the figure stays unchanged in the next month and then fall to 9.5 degree in December.

On the contrary, in Sydney, the temperature decrease insignificantly from 25.5 degree in January to the lowest of 16 degree in July, before a gradual rise to 25 degree in December. Meanwhile, the table indicates that New York has the largest number of sunshine hours per year with 2535 hours, came after by Sydney and London with 2473 hours and 1180 hours respectively.

In conclusion, London is likely to be the coldest city because its annual hours of sunshine is less than two others.

I dont know what to do can someone please help me ASAP
ANTONII [103]

Answer:

In the explanation. :)

Explanation:

Human powered generators are the best source for the rescue team. We cannot always depend on the sun. What if the sun is not out that day? What if it's a rainy day? What if the sun is what's causing the rescue team to come out? Human powered generators are sometimes untrustworthy, but at the same time we know that at least it's a step away. We don't have to wait all-day for the sun to help out. Of course, the energy from the sun is always going to be there and won't cause anybody hurt, harm, or danger, but at the same time we can always convert to human powered generators and they'll work just as perfect.

Hope this helps, have a great day!
