The correct answer is option (C) "I and III."

Both statements I and III are correct regarding seed dormancy. Statement II is incorrect.

Statement I states that seed dormancy is a result of endogenous control, which is true. Endogenous factors within the seed, such as hormones and genetic mechanisms, regulate the dormancy period and prevent germination until certain conditions are met.

Statement II suggests that delayed germination is advantageous to plants. However, this statement is incorrect. Delayed germination is not universally advantageous to plants. While some seeds may benefit from delayed germination to ensure favorable environmental conditions for growth and survival, other seeds may have evolved strategies for immediate germination. The advantage of delayed germination depends on the specific ecological context and the species involved.

Statement III states that an impermeable and hard seed coat results in the dormancy of the seed, which is true. A hard and impermeable seed coat can prevent water uptake and gas exchange, thus inhibiting germination. This dormancy mechanism ensures that the seed remains dormant until conditions are favorable for germination, such as sufficient moisture, temperature, or light.

In conclusion, statements I and III are correct regarding seed dormancy. Seed dormancy is controlled by endogenous factors, and an impermeable and hard seed coat can contribute to the dormancy of the seed. However, statement II, suggesting that delayed germination is advantageous to plants, is incorrect.

Enzymes catalyze natural chemical reactions, using less energy. So the most likely role of enzymes in a chemical reaction is to reduce the amount of activation energy required for the reaction to proceed. Option C.

-------------------------------------------------------

Let us first describe and analyze the graphs

Now, we need to interprete these graphs. And to do so, let us review some framework.

Enzymes are catalytic intracellular molecules or polypeptides that accelerate different natural chemical reactions.

Enzymes have specific binding sites to substrate molecules and turn them into product molecules.  They are in charge of catalyzing cell metabolism.

When talking about catalysis, we refer to an acceleration process. Natural reactions occur with or without the enzyme, but

→ in the absence of enzyme, the reaction

→ in the presence of enzyme, the reaction

The activation energy is the needed energy to break the chemical bonds of reactants to produce new products. For this to occur, reactant molecules need to get to a transition state. So the activation energy is the amount of energy necessary for a reactant to reach its transition state.

The transition state always requires more energy than the reactants and products by themselves. This is why in the reaction curves, the highest peak corresponds to the activation energy.

Now we can make the following graphs interpretation:

The conclusion is that The enzyme reduces the amount of activation energy required for the reaction to proceed.

Messenger RNA molecules are very difficult to isolate in prokaryotes because they are rather quickly degraded in the cell. The reason for the degradation of messenger RNA molecules in prokaryotes is that prokaryotes have no nuclear membrane, which separates transcription and translation.

The messenger RNA (mRNA) molecules produced during transcription in prokaryotes are vulnerable to degradation because the ribosomes and RNase enzymes, which function in translation and mRNA destruction, are located in the same compartment of the cell

Because of the proximity of mRNA to ribosomes and RNase enzymes, the mRNA molecules produced during transcription can be easily and quickly degraded or destroyed.

RNA molecules are crucial organic molecules that play a crucial role in genetic and biological processes. RNA is synthesized by RNA polymerase from a DNA template during transcription, and the resulting RNA strands serve as templates for protein synthesis in ribosomes, leading to the formation of polypeptide chains.

Answer:

Some scientists believe that there were huge fires and the skies were dark and full of pollution due to a meteor exploding and killing off the dinosaurs, and if it's true that this occurred, the Ostrich evolved to be a land animal due to it being too dangerous in the air for them. The long neck may have developed to help them get food that was higher up which is the same speculation for the Giraffe. To stay on land they had to be stronger, bigger, and faster than they were in flight.

Explanation:

(A) The answer to the initial value problem is given by \(\(y = (x^2 + 1)e^x\)\), where \(\(y' - y = 2xe^{2x}\)\) and \(\(y(0) = 1\)\).

(B) The resolution to the initial value problem can be expressed as \(\(y = \frac{2x - (\pi - 1)}{\sin(x)}\)\), where \(\(y' + \cot(x)y = 2\csc(x)\)\) and \(\(y\left(\frac{\pi}{2}\right) = 1\)\).

(A) To solve the initial value problem:

\(\[y' - y = 2xe^{2x}, \quad y(0) = 1\]\)

We can use an integrating factor method. To begin, let us express the equation in its standard form:

\(\[y' - y - 2xe^{2x} = 0\]\)

The integrating factor \(\(I(x)\)\) is given by \(\(I(x) = e^{\int -1 \, dx} = e^{-x}\)\).

To obtain the solution, apply the integrating factor to both sides of the equation and perform the multiplication.

\(\[e^{-x}(y' - y) - 2xe^{2x}e^{-x} = 0\]\)

This simplifies to:

\(\[e^{-x}y' - e^{-x}y - 2x = 0\]\)

Now, observe that the expression on the left-hand side represents the derivative of \(\((e^{-x}y)\)\) with respect to \(\(x\)\).

Using this observation, we can rewrite the equation as:

\(\[\frac{d}{dx}(e^{-x}y) - 2x = 0\]\)

Integrating both sides with respect to \(\(x\)\), we get:

\(\[e^{-x}y - \int 2x \, dx = C\]\)

where \(\(C\)\) is the constant of integration.

Integrating \(\(\int 2x \, dx\)\), we have:

\(\[e^{-x}y - x^2 + C = 0\]\)

To find the constant \(\(C\)\), we use the initial condition \(\(y(0) = 1\)\).

Substituting \(\(x = 0\)\) and \(\(y = 1\)\) into the equation, we get:

\(\[e^{0} \cdot 1 - 0^2 + C = 0\]\)

\(\[1 + C = 0\]\)

\(\[C = -1\]\)

Substituting \(\(C = -1\)\) back into the equation, we have:

\(\[e^{-x}y - x^2 - 1 = 0\]\)

Finally, we can solve for \(\(y\)\) by isolating it:

\(\[e^{-x}y = x^2 + 1\]\)

\(\[y = (x^2 + 1)e^x\]\)

(B) To solve the initial value problem:

\(\[y' + \cot(x)y = 2\csc(x), \quad y\left(\frac{\pi}{2}\right) = 1\]\)

We can use an integrating factor method. To begin, we will rewrite the equation in standard form:

\(\[y' + \cot(x)y - 2\csc(x) = 0\]\)

The integrating factor \(\(I(x)\)\) is given by:

\(\(I(x) = e^{\int \cot(x) \, dx} = e^{\ln(\sin(x))} = \sin(x)\).\)

Apply the integrating factor to both sides of the equation and perform the multiplication.

\(\[\sin(x)(y' + \cot(x)y) - 2\csc(x)\sin(x) = 0\]\)

This simplifies to:

\(\[\sin(x)y' + \cos(x)y - 2 = 0\]\)

Now, observe that the expression on the left-hand side represents the derivative of \(\((\sin(x)y)\)\) with respect to \(\(x\)\). Using this observation, we can rewrite the equation as:

\(\[\frac{d}{dx}(\sin(x)y) - 2 = 0\]\)

Integrating both sides with respect to \(\(x\)\), we get:

\(\[\sin(x)y -\)\(\int 2 \, dx = C\]\)

where \(\(C\)\) is the constant of integration. Integrating \(\(\int 2 \, dx\)\), we have:

\(\[\sin(x)y - 2x + C = 0\]\)

To find the constant \(\(C\)\), we use the initial condition \(\(y\left(\frac{\pi}{2}\right) = 1\).\)

Substituting \(\(x = \frac{\pi}{2}\)\) and \(\(y = 1\)\) into the equation, we get:

\(\[\sin\left(\frac{\pi}{2}\right) \cdot 1 - 2\left(\frac{\pi}{2}\right) + C = 0\]\)

\(\[1 - \pi + C = 0\]\)

\(\[C = \pi - 1\]\)

Substituting \(\(C = \pi - 1\)\) back into the equation, we have:

\(\[\sin(x)y - 2x + (\pi - 1) = 0\]\)

Finally, we can solve for \(\(y\)\) by isolating it:

\(\[\sin(x)y = 2x - (\pi - 1)\]\)

\(\[y = \frac{2x - (\pi - 1)}{\sin(x)}\]\)

\(\(y = \frac{2x - (\pi - 1)}{\sin(x)}\).\)
