Answer:
The correct answer is option a.
Explanation:
Quantitative research has an application in quantifying the problem by producing numerical data or data, which can be converted into usable statistics. This form of research utilizes measurable data to construct facts and to uncover patterns in research. The quantitative data collection procedures are much more saturated in comparison to qualitative data collection procedures. It comprises various kinds of surveys like paper surveys, online surveys, kiosk surveys, and mobile surveys, face-to-face interviews, longitudinal studies, telephone interviews, and systematic observations, however, in random sampling. In the process, a variety of selection procedures in which sample members are chosen by chance, however, with a known possibility of selection.
Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)
Explanation:
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.
When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.
Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur
--> in body cells or
--> during gamete formation.
Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution
Hi Gigi, my name is Ryleigh, I might be able to help, but I need to know what are the conditions, and what is the question asking?
The arrangement are SA node, internal pathways, AV node, AV
bundle, Bundle branches and Purkinje fibers. The anatomy of the intrinsic
conduction system causes contraction of the ventricles to activate at the apex
and move superiorly so blood is forced upward, toward the semilunar valves.
Answer & Explanation:
An organic molecule is one which contains carbon, although not all compounds that contain carbon are organic molecules. ... Although carbon is present in all organic compounds, other elements such as hydrogen (H), oxygen (O), nitrogen (N), sulfur (S) and phosphorus (P) are also common in these molecules.
