Answer:
Linkage may be defined as the transmission of chromosome to the next generation that are located on same chromosome. Linkage results in the formation of recombination progeny.
PDS (parental ditypes) and non parental diypes can be used to find linkage in the Neurospora and other organism Parental ditypes has the genotype same as parental genotype whereas non parental ditypes contains recombinant progeny. If the ratio and arrangement of PDS and NPDs is 2:4:2 or 2:2:2:2. This means linkage is present between the gene and centromere of an organism.
Answer:
(2) diffusion
Explanation:
Diffusion is a process in which molecules moves from a region of higher concentration to the region of lower concentration. In this condition, plant roots contain high concentration of nitrates than soil so nitrates moves from roots through semi-permeable to the soil by the action of diffusion until the concentration is uniform or equilibrium.
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.

Answer:
disruptive selection
Explanation:
Disruptive selection may be defined as a type of a natural selection which selects against some average individual in a given population. These makeup of such a type of the population shows the phenotypes of both the extremes of characteristics but they have very few individuals in the middle.
Disruptive selection is also known as diversifying selection.
In the given context, the beaks of an African seedcracker finches may be small or may be large but they are not of the intermediate size. Such a selection is known as disruptive selection in species.
