Correct Answer: A)

3P\(_1\)

Explanation

In order to explain this question, we should first recall the ideal gas law, which relates the pressure, volume, and temperature of an ideal gas. The ideal gas law is given by the equation:

\(PV = nRT\)

Where P is the pressure, V is the volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in Kelvin.

In this question, we are given that the volume of the gas is halved, which means that the final volume V\(_2\) is half of the initial volume V\(_1\). Mathematically, this can be represented as:

\(V_2 = \frac{1}{2}V_1\)

Additionally, we are given that the temperature increases by half its initial value. Therefore, the final temperature T\(_2\) is 1.5 times the initial temperature T\(_1\). Mathematically, this is:

\(T_2 = 1.5T_1\)

Now, we can use the ideal gas law to find the final pressure P\(_2\). Since the number of moles and the ideal gas constant remain constant, we can write the initial and final states of the gas as:

\(P_1V_1 = nRT_1\) and \(P_2V_2 = nRT_2\)

Divide the two equations to eliminate nR:

\(\frac{P_2V_2}{P_1V_1} = \frac{T_2}{T_1}\)

Substitute the expressions for V\(_2\) and T\(_2\):

\(\frac{P_2(\frac{1}{2}V_1)}{P_1V_1} = \frac{1.5T_1}{T_1}\)

We can see that V\(_1\) and T\(_1\) cancel out:

\(\frac{P_2}{2P_1} = 1.5\)

Finally, isolate P\(_2\) to find the final pressure:

\(P_2 = 3P_1\)

Therefore, the correct answer isOption A: 3P\(_1\).

Correct Answer: A)

Zn/Zn\(^{2+}\)//Cu\(^{2+}\)/Cu

Explanation

In a Daniell cell, the reaction that occurs is an electrochemical reaction involving the transfer of electrons between two different metals. The metals used in a Daniell cell are zinc (Zn) and copper (Cu), and their respective ions, Zn\(^{2+}\) and Cu\(^{2+}\). The reaction can be represented as:

Zn/Zn\(^{2+}\)//Cu\(^{2+}\)/Cu (Option A)

In this representation, the forward slash (/) separates the metal from its respective ion, and the double forward slash (//) separates the two half-cells of the Daniell cell. The half-cell on the left (Zn/Zn\(^{2+}\) represents the anode, where oxidation occurs, and the half-cell on the right (Cu\(^{2+}\)/Cu) represents the cathode, where reduction occurs.

During the reaction, zinc loses two electrons and forms zinc ions (Zn\(^{2+}\) at the anode, while copper ions (Cu\(^{2+}\) gain two electrons to form copper metal at the cathode.

The overall reaction can be written as:

Zn(s) + Cu\(^{2+}\)(aq) ? Zn\(^{2+}\)(aq) + Cu(s)

This reaction allows for the flow of electrons in the external circuit and generates electrical energy. The Daniell cell is an important concept in electrochemistry, as it demonstrates the principles of redox reactions, galvanic cells, and the generation of electricity from chemical reactions.

Correct Answer: C. Watershed

Correct Answer: A. orchard

Explanation

(a) Difference between tropic movement and nastic movement

(b) How light brings about tropic movement in stem and root of a flowering plant:

(i) When unilateral light falls on the stem, the auxin/growth hormone/IAA is displaced from the lighted to the dark side.

(ii) The increase in auxin concentration on the dark side increases growth on that side causing the stem to bend towards the light/positive phototropism.

Roots:

(i) The auxin is displaced from the lighted side to the dark side.

(ii) The increase in auxin concentration retards growth on the dark side causing the root to bend away from the light/negative phototropism.

(c) The following would be observed when a growing seedling is placed horizontally:

(i) Shoot bends upwards, showing negative geotropism/positive phototropism.

(ii) Root bends downwards, showing positive geotropism/negative phototropism.

(d) Functions of the Pituitary gland:

(i) Stimulates growth/growth of long bones/cell division.

(ii) Stimulates production of sex-hormones/named sex hormones.

(iii) Stimulates production of anti-diuretic hormone/ADH/regulation of water re-absorption in the kidney/osmos regulation.

(iv) Produces hormones which control other endocrine glands/stimulates thyroid gland/adrenal cortex.

(v) Stimulates protein synthesis.

(vi) Induces birth by contraction of uterine muscles/production of oxytoxin.

(vii) Induces milk secretion/produces prolactin.

(viii) Controls egg and sperm production.

(e) Differences between growth in plants and animals:
