He association of two or more polypeptides in a multimeric protein is known as the <span>Quaternary structure.</span>
Answer:
1. Archipelago in Ecuador
2. Different beaks
3. He used Darwinism/ survival of the fittest / evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. mutation, gene flow, genetic drift, and natural selection.
Mutation creates new genetic variation in a gene pool.
Gene flow and genetic drift alter allele frequencies in a gene pool.
5. The finches have few predators / competition for food.
Explanation:
<span>Lysosomes are organelles which are responsible for breaking down and digesting wastes in the cell.
Lysosomes and vacuoles have the same functions. Both are enclosed organelle compartments within a cell and are recycling centers responsible for breaking down substances or complex molecules that goes into a cell. Both are sacs which contain digestive enzymes for breaking down foreign materials, food, and pathogens. Vacuoles are found in plant cells and lysosomes are in animal cells. Vacuoles play an important role in plant’s food production. It stores water and hydration of plants.<span>

Parent material is responsible for the physical and chemical properties of the soil.
<h3>What is Parent material?</h3>
This is defined as materials such as rocks or organic matter which acts as the starting stage for soil development.
This material are influenced by factors such as weathering which determines the physical and chemical properties of the soil.

Nuclear magnetic resonance provide information on the structure of a purified protein based on its nuclear spin properties in a magnetic field, whereas X-Ray crystallography uses diffraction pattern of protein in solid phase.
Explanation:
Nuclear magnetic resonance is a spectroscopic technique that involves change in nuclear spin energy in presence of an external magnetic field. It is based on the absorption of electromagnetic radiation in the radio-frequency region.
X-Ray crystallography is a method of determining the arrangement of atoms within a crystal.This technique is based the fact that when a beam of X-ray strikes a crystal, the beam gets diffracted. From the angle and intensities of diffraction a three-dimensional structure of electron density can be determined .
