A plane mirror always forms a virtual image that is the same size as the object and is erect.

A concave lens always forms a virtual image that cannot be projected on a screen; hence, a real image cannot be formed.

Aldehydes are generally more reactive than ketones due to the presence of the hydrogen atom attached to the carbonyl carbon.

An ideal gas is considered to have no volume and no intermolecular forces, making option D correct.

For capacitors in parallel, the total capacitance is the sum of the individual capacitances: C_total = C₁ + C₂ + ...

Electric current flows from positive to negative in a circuit.

Exothermic reactions release heat, resulting in a negative enthalpy change.

Ideal gases are considered to have no volume and no intermolecular forces.

Laminar flow is characterized by smooth and orderly fluid motion, typically occurring at low velocities.

The Arrhenius equation relates temperature to the rate constant and includes activation energy.

Ketones generally have higher boiling points than aldehydes due to stronger dipole-dipole interactions.

[Ag(NH3)2]+ is a linear complex because silver (Ag) has a coordination number of 2 with two bidentate ligands.

The complex [Cr(NH3)6]3+ is octahedral with a coordination number of 6, as it is surrounded by six ammonia ligands.

The equilibrium constant Kc is dependent on temperature; changing the temperature will change the value of Kc.

A solenoid produces a uniform magnetic field inside and negligible field outside when it is long compared to its diameter.

Inside a long solenoid, the magnetic field is uniform and parallel to the axis of the solenoid, provided the solenoid is long enough.

Gases have the weakest intermolecular forces, allowing particles to move freely.

After fertilization, the ovary of the flower develops into a fruit, which contains the seeds.

The ovule develops into a seed after fertilization occurs.

The face-centered cubic (FCC) structure has the highest packing efficiency of approximately 74%.

Chloroplasts are found in plant cells and are responsible for photosynthesis, while animal cells do not have them.

Chloroplasts are found only in plant cells and are responsible for photosynthesis.

The anther is the part of the stamen that produces pollen.

The esophagus is part of the digestive system, while the trachea, larynx, and bronchi are components of the respiratory system.

Bone marrow is the primary site for the production of red blood cells in the human body.

The sarcoplasmic reticulum is responsible for storing calcium ions, which are crucial for muscle contraction.

Motor neurons transmit nerve impulses to muscle fibers, initiating muscle contraction.

T-tubules (transverse tubules) are responsible for transmitting the action potential deep into the muscle fiber.

Valves in the heart prevent the backflow of blood, ensuring it flows in one direction through the heart chambers.

Glucose is not typically found in urine unless there is a condition such as diabetes mellitus.
