In a concentration cell, the electrodes are made of the same metal but have different concentrations of the electrolyte.

The genotype of the F1 generation from a cross between TT and tt will be Tt (all offspring will be heterozygous).

The height of the F1 generation will be tall, as tall is the dominant trait.

The arrangement of particles in a crystal lattice is primarily determined by intermolecular forces, which dictate how particles pack together.

The expected phenotypic ratio in a dihybrid cross is 9:3:3:1.

In a fluid, pressure increases with depth due to the weight of the fluid above.

A rabbit is a primary consumer as it feeds on plants (producers).

The correct order of energy flow in a food chain is Producer → Consumer → Decomposer.

Systematic errors lead to biased results, consistently deviating from the true value.

The range is calculated as (10.0 - 0.5) cm to (10.0 + 0.5) cm, which is 9.5 cm to 10.5 cm.

When a p-n junction is forward biased, the depletion region narrows, allowing current to flow.

In the p-type region of a p-n junction, holes are the majority charge carriers.

In a pedigree chart, a filled circle represents an affected female.

When a PN junction diode is forward biased, the depletion region narrows, allowing current to flow.

An electric field is formed at the junction of p-type and n-type materials due to the diffusion of charge carriers.

An increase in the prey population typically leads to an increase in the predator population due to more available food.

Predators help control the population of prey species, maintaining a balance in the ecosystem.

Increasing the concentration of a reactant will shift the equilibrium position to the right, favoring the formation of products.

For an exothermic reaction, increasing the temperature shifts the equilibrium to the left, favoring the reactants.

Reduction is defined as the gain of electrons, which decreases the oxidation state of the element.

If the forward reaction is exothermic, the reverse reaction must be endothermic, as it absorbs heat.

Total resistance in series is R_total = R1 + R2 + R3 = 1 + 2 + 3 = 6Ω.

In a series circuit, removing one resistor breaks the circuit, causing the current to become zero.

According to Ohm's law, I = V/R. If R is doubled, the current I will be halved for a constant voltage V.

At resonance in a series RLC circuit, the impedance (Z) is equal to the resistance (R) because the inductive and capacitive reactances cancel each other out.

At resonance in a series RLC circuit, the impedance is minimum, and the circuit behaves like a purely resistive circuit.

At resonance in a series RLC circuit, the impedance is minimum, and thus the current is maximum.

At resonance in a series RLC circuit, the total impedance is minimum and is equal to the resistance (R) of the circuit.

In a simple cubic lattice, there is 1 atom per unit cell (1/8 atom from each of the 8 corners).

Maximum velocity occurs at the mean position where the displacement is zero.
