<h2>Answer:</h2>

The statements 3 and 5 can be two generalization made by the information of a closed system.

<h3>Explanation:</h3>

A closed system is system in which neither matter nor energy cannot cross the boundaries of the system.
So the statement 3 which is the amount of matter remains same in the system is correct one on the bases of the law of conservation of mass.
This law states that neither mass and energy can be created nor destroyed but they can change from one form to another form.
In the given system, reaction of matter is in cyclic form, the starting and stopping points of reaction can be well defined on the basis of reaction.

Answer: The correct answer is option 3) The amount of matter within the system remains the same and 5) The cycle has a well-defined starting and stopping point.

A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.

In a closed system, the cycle has a well-defined starting and stopping point.

Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 1) and 5)

Now can you predict nucleotide quantities in a hypothetical scenario with more than four different types of nucleotides? An alie

den301095 [7]

Answer:

16% is G

12% is T

12%is A

22% is X

Explanation:

Given that each nucleotide is complimentary to another nucleotide, there cannot be more of one than the other. For example, C bonds to G, so there cannot be more C than G, because there would be nothing for it to bond to.

So if there is approximately 16% of the genome composed of C, that would mean that approximately 16% is composed of G (for it to bond to).

The same logic can be used to determine the amount of nucleotide X is present. If Y binds to X, and approximately 22% is composed of nucleotide Y, then the same percentage can be given to nucleotide X, and say the amount of X is 22%.

Now all of the nucleotides have to add up to 100%, so:

A + T + G + C + X + Y = 100%

A + T + (16%) + (16%) + (22%) + (22%) = 100%

A + T = 24%

Given that A binds to T, they must be equal to each other, hence we can say that the concentration of A, equals the concentration of T.

Therefore, the concentration of A is 12%, and the concentration of T is also 12%.

What act as a root in the pteridophytes

ra1l [238]

Answer:

The root system is always adventitious. The stem is either underground or aerial. The leaves may be microphylls or megaphylls. Their other common characteristics include vascular plant apomorphies (e.g., vascular tissue) and land plant plesiomorphies (e.g., spore dispersal and the absence of seeds).

The magnets point North when the Earth's magnetic field has (p2)<br><br>need some help :)

Natali5045456 [20]

<h2><u>EARTH'S MAGNETIC FIELD</u></h2>

The magnets point North when the Earth's magnetic field has?

<h2><u>ANSWER</u></h2>

I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.

In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.

<h2><u>THE MAGNETIC REVERSAL</u></h2>

The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.
