The urban environment usually refers to the city, like Chicago. Urban is the opposite of rural. The rural area is known as the countryside. Urban environments often include; tall skyscrapers, loud streets, and the smells of different kinds of foods.
Answer:
Contamination of the control sample (negative control) with DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories to amplify a target DNA fragment using primer pairs and DNA polymerase. In PCR experiments, it is imperative to include both positive and negative controls. The positive control refers to the amplification of a PCR product (amplicon) of known molecular size during PCR reaction in order to ensure the correct molecular weight of the target DNA fragment. The negative control refers to the inclusion of a sample without DNA in order to ensure that no contamination with DNA has occurred in the other samples.
The other molecules are triglycerides, low density lipoprotein, and high density lipoprotein.
Answer:
systems (system biology)
Explanation:
Systems biology can be defined as a methodology whose interest is to understand the high scale levels of complexity in biology (i.e. organism level, tissue level, cell function, etc) by integrating information/data from different sources, and thus examine the interaction between biological components. This approach is contrary to reductionism, which is another approach used in biology research. Therefore, systems biology is a holistic approach aimed at modeling complex biology systems by applying computational and mathematical methods, enabling to understand biological systems.
Answer:
The correct option is <em>A) They represent injuries to skin and bone. Skin and bone are both organs.</em>
Explanation:
When Lindsey tripped, she got a cut in her skin at the knee area. The knee cap is a bone present in the knee protects the knee joint and articulates with femur. Both the skin and bones are organs of the body which are made up of different kinds of tissues.
Other options like option B is false because blood is not an organ, it can be considered as a tissue or a transporting fluid.
