The statement that correctly describes the presence of freckles is there are two alleles for freckles, hence option B is correct.
An allele is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution.
Small, brownish to reddish dots on your skin are known as freckles. They frequently appear on your face, neck, back, upper chest, hands, and arms, as well as other sun-exposed places. Even though freckles are typically not harmful, it is always a good idea to keep an eye out for any changes.
Therefore, the statement that correctly describes the presence of freckles is there are two alleles for freckles, hence option B is correct.

Answer:
Physical Layers:
- Crust
- Mantle
Compositional Layers:
- Asthenosphere
- Mesosphere
Explanation:
Physical Layers refer to the layers of the Earth based on their physical properties such as their state (solid or semi-solid) and how they behave. The two primary physical layers are the Crust and Mantle.
- Crust: The Earth's Crust is the outermost layer, which includes the solid ground we walk on. It is relatively thin compared to the other layers and is where we find the continents and ocean floors.
- Mantle: The Mantle lies beneath the crust and is semi-solid, extending to a depth of about 2,900 kilometers (1,800 miles). It's responsible for the convective movement of the Earth's tectonic plates.
Compositional Layers, on the other hand, are based on the chemical composition of the Earth's interior. They include:
- Asthenosphere: The Asthenosphere is part of the upper mantle and is composed of partially molten rock. It's semi-fluid, allowing for the movement of tectonic plates. This is crucial for plate tectonics and the Earth's surface dynamics.
- Mesosphere: The Mesosphere is not typically considered a distinct compositional layer in the Earth, but rather part of the lower mantle. It consists of solid rock that behaves plastically, allowing for convection currents to occur deep within the Earth.

Answer: Diffusion
Explanation:
The osmosis is explained as the selective permeability of the membranes which allows the movement of the solute from higher concentration to lower concentration.
This is associated with diffusion which can be defined as the random movement of the particles in order to attain equilibrium.
The diffusion allows the movement of the particles and osmosis allows the movement of only selective materials.
