marin [14]

Answer:

The correct option is <em>B. Crossing- over </em>

Explanation:

In biology, crossing over can be described as a phenomenon by which homologous chromosomes exchange segments during the process of meiosis.

The unexpected results came because the DNA segment between the homologous chromosomes was exchanged during meiosis. The alleles got shuffled by this process and hence showed the unexpected results.

Crossing over and independent assortment are phenomenon which occurs only during the process of meiosis. These phenomenons cannot be observed during mitosis.

Most of the joints in the appendicular skeleton are __________ joints.
Semmy [17]

Most of the joints in the appendicular skeleton are synovial joints.

So, the correct option is (c).

  • A joint, sometimes referred to as an articulation, is where two or more bones come together. The names of two bones are included in each articulation.
  •  Immobile joints are ones that do not permit movement at the joint sites .These joints don't have a joint cavity; instead, dense fibrous connective tissue, typically collagen, holds the bones physically together.
  • A synovial membrane-lined joint capsule that produces synovial fluid surrounds and protects the two of them.
  • Specialized joints known as cartilaginous joints can be identified by their structural characteristics.
  • In fibrous joints, white connective tissue  fibres that travel from one articulating portion to the next separate the articulating parts.
