the DNA molecule is t-RNA which curlers up to be transported and then elongates to read the info on the protein
There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms.
A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. <span>Both plant and animal cells are eukaryotic cells.

Answer: <u>A.</u> - Add more lights to the series circuit
Explanation:
(^^ <u>D.</u> IS THE INCORRECT ANSWER!!! ^^)
In a series circuit, the total resistance is equal to the sum of the resistance of each component. Adding more lights will increase the total resistance of the circuit, reducing the flow of current to an acceptable, safe level. If some lights were replaced by wires, the resistance would decrease, and the current would increase. The current also depends on voltage, and increasing voltage would increase the current. If the lights were connected in a parallel circuit, the resistance would be a small fraction of its current value.
Answer:
Population A has 4590 and population B has 1520 bacteria
Explanation:
Let’s mark bacteria:
a - bacteria from population A
b - bacteria from population B
Every bacteria <em>a</em> needs 4 units of the first nutrient and every bacteria <em>b</em> needs 1 unit of the same nutrient, so we can write it down as:
4*a + 1*b = 19880
Let’s do the same for the second nutrient. Every bacteria <em>a</em> needs 5 units of the second nutrient and every bacteria <em>b</em> needs 6 units of the second nutrient:
5*a + 6*b = 32070
Now there are two equations and two unknowns. From the first equation, we can separate <em>b</em>:
b = 19880 - 4a
Let’s place this <em>b</em> to the second equation:
5a + 6*(19880 - 4a) = 32070
5a + 119280 - 24a = 32070
119280 - 32070 = 24a - 5a
19a = 87210
a = 4590
This can be brought back to: b = 19880 - 4a
b = 1520
