<u>Answer</u>:

A - 50

B - 12 (or 12.5 if any decimals are included)

C - 3

D - 2

E - 0

In the table it seems that the values for Radioactive Atoms (Predicted) are the values for 0.5^{π} multiplied by 100. For smaller numbers, they are rounded to two decimals such as for 0.0625 which if multiplied by 100 should be 6.25. This value is rounded to 6.

Similar is 0.0078125 which is rounded to 0.01 only. When this is multiplied by 100, it gives the value of 1. Thus, the values for D and E are most probably also 2 and 0. If the same logic is followed as for value 0 as they are rounded to 0.02 and 0.00 before multiplying by 100.

Another way to look at this is that the value is half of that of the previous life cycle. Thus, A is half of 100 which is 50 and 25 (life-cycle 2) is half of 50. My answers are also respecting this trend.

⭐️HELP PLEASE<br><br> Why did prokaryotic cells come before eukaryotic cells?
stiks02 [169]

Answer:

The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms. Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union.

Hypothesize whether prokaryotic cells might have been symbiotic before the evolution of eukaryotic
lorasvet [3.4K]
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!

Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.

But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!

Repeating the experiment multiple times
nalin [4]

Answer:

C) Practicing good scientific method and practices.

Explanation:

The text states, "repeating the experiment multiple times," as well as other preparations that a good scientist uses.

Doing something multiple times over is a good sign of a good scientific method.

Taking careful measurements, having several researchers run the same experiment, and only testing one variable at a time are all good practices that a scientist should use.
