Answer: The cell membrane represents several types of different molecules.
Explanation:
Its basic function is to separate the intracellular part from the extracellular parts. Biological membranes are globally built on the same principle and consist of lipids, proteins, glycolipids, and glycoproteins. Two layers of lipids form the structural matrix of the membrane. Membrane proteins are key to membrane function. The composition also includes sugars that do not come independently but are covalently bound to membrane proteins or lipids.

Answer: The challenges of immigration are, more often than not, negotiated in the context of the family (Carranza 2001).

Explanation: A purposive sample was chosen in order to provide some diversity to the range of the accounts regarding mother–daughter negotiation. The purposive sample provided richness along many dimensions such as socio-economic-political religious affiliations, migration paths, etc. The sample design was fairly complex involving two sets of participants. Each of the two sets included mothers and their daughters. Participants in these sets were interviewed individually.These two sets were: (i) The Mother–Adolescent
Daughter Set which included Salvadorian immigrant mothers and at least one of their adolescent daughters between the ages of 15 and 17 years who were born in Canada or abroad; and (ii) The Mother–Adult Daughter Set which included Salvadorian immigrant mothers and at least one of their adult daughters between the ages of 19 and 30 years who grew up in Canada or arrived before becoming an adolescent. Mothers and daughters in these two groups were interviewed individually because ‘in-depth interviews provided the possibility to learn to see the world from the eyes of the person being interviewed’ (Ely 1991, p. 58). These in-depth conversations allowed obtaining information about the participants’ individual perceptions regarding their positioning as they settled into Canadian context.
