Answer:
246
Explanation:
Increased amount / current population = 972
Amount released = 108
time(t) = 2years
Using the exponential growth function :
f(t) = A*g^t
Where g = growth rate
To obtain the growth rate = g
972 = 108 * g^2
g^2 = 972 / 108
g^2 = 9
g = 3
To determine population after 9 months :
9 months to years = (9/12) = 0.75
t = 0.75
f(0.75) = 108*(3^0.75)
f(0.75) = 108 * 2.2795070
f(0.75) = 246.18676
= 246

A theory.
Explanation:
Answer: DNA transcription
Transcription is the process where RNA is created from DNA using RNA Polymerase. This creates an mRNA strand carrying genetic instructions which will be translated into a protein during translation.
The process of creating RNA from DNA is known as transcription. This process involves an enzyme known as RNA Polymerase which unzips the DNA's double helix structure to use one strand as a template for building an mRNA molecule. The constructed mRNA molecule carries genetic instructions from the DNA and these instructions will subsequently be read by ribosomes in the protein synthesis process, also known as translation.
Transcription can be divided into three main stages: initiation, elongation, and termination. During initiation, the RNA Polymerase attaches to a specific area on the DNA strand. For elongation, the enzyme moves along the DNA template, synthesizing a new mRNA strand in a 5' to 3' direction. Once the RNA Polymerase encounters a termination signal on the DNA, transcription stops, and the mRNA molecule is released.

The Earth layer composed of liquid iron and nickel is the Outer Core. This is the third layer from the surface and its fluid motion creates Earth's magnetic field.
The layer of the Earth which is primarily composed of liquid iron and nickel is the Outer Core. The Earth can be divided into four main layers: the crust, the mantle, the outer core, and the inner core. The Outer Core, which is the third layer of the Earth if you start from the surface, is a sea of mostly molten iron and nickel. This liquid layer is about 2200 kilometers (1367 miles) thick and creates the Earth's magnetic field due to the movement within it.

B. finding a comet
C. examining the structure of plant cells
D. building a garage
2. Which of the following procedures involves a physical change in one of the substances?
A. creating salt by reacting sodium metal and chlorine gas
B. allowing a nail to rust
C. building a model rocket propelled by mixing baking soda and vinegar
D. grinding chalk into a fine powde 3. You have three molecules of glucose (3C6H12O6). How many oxygen atoms do you have?
A. 1
B. 3
C. 6
D. 18
Question 1:
The right answer is A
Chemistry is a science of experimental nature that studies the composition of matter and its transformations.
Chemistry is thus interested in the elements that constitute matter (atoms, ions, etc.), in their properties and in the chemical bonds that can be created between them.
Question 2:
The right answer is A
Sodium chloride is an ionic chemical compound of the formula NaCl. It is more commonly called table salt or cooking salt, or simply salt in everyday language.
It is clear that it exists in the form of solid salts.
during his training, there was a physical change of sodium (metal) and chlorine (gas) into a salt.
Question 3:
This question is a little bit tricky
If we assume that the question is aimed at finding the total number of oxygen in all three molecules together, the answer is 18.
A glucose molecule is made up of 6 atoms of oxygens if we have three glucose molecules (assuming that they are bound), we multiply by 3 and this gives us 18 oxygen atoms.
