Answer: The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building.
Explanation:
Answer:
that means they are not a prey to any animal
Answer:
Aerobic bacteria can be used to use the available oxygen in the water to degrade the pollutants in the waste and convert it into energy it can use for its metabolic processes.
Answer:
This protein consists of 8 subunits of equal size linked by disulfide bonds
Explanation:
The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g., β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.
Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
