<h2>Gel electrophoresis determine the size of fragments</h2>
Explanation:
- Through the use of this technique DNA sequences were separated to each other for analysis of DNA in forensic investigation.
- This technique is used in DNA fingerprinting for examination of different cases.DNA is negatively charged molecule is determined through the specific fragment size.
- Size determination of DNA fragments this technique of agrose gel were identify the number of fragments which migrate from one place to another place through measure its distance of migration.
- To generate the standard curve of distance of fragments in electrophoresis with the measurements of distance of migration at x axis and long base pairs of DNA at y axis.
- Determine the length of each fragments through the standard curve graph in which the intersected lines will show the length of fragments to migrate in this technique of DNA separation.
Answer:
One thing that a scientist might ask about the movement of carbon dioxide through the whale and its surrounding is “how did the whale get the carbon dioxide?”. Another thing that a scientistmay ask about this is “how does the carbon dioxide affect the ecosystem?”
Answer:a positive feedback
Explanation: positive feedback is a type of feedback mechanism employed by the body,in which an output is enhanced or acclerated.
In contrast to negative feedback where the body regulates it's internal conditions by reducing the effect of a stimuli,In positive feedback ,the body enhances the effect of the stimuli.
It is not common as negative feedback in homeostasis.
An example is the increasing release of oxytocin to promote contractions during childbirth,until the child is born.
Another example is the accumulation of blood platelet , in the site of blood vessels injury to
cause blood clotting.
Answer:
<u>mitochondria; cytoplasm </u>
<u>Explanation:</u>
Remember, the main difference between the two types of respiration is that Aerobic respiration<em> relies on oxygen</em> to break down body fats and sugars into energy. While Anaerobic respiration <em>does not</em> require oxygen to produce energy from fats and sugars.
Thus, In living organisms, it is believed that Aerobic respiration takes place in the <u>mitochondria</u> inside cells while Anaerobic respiration takes place in the <u>cytoplasm </u>of a cell.
The second answer is correct.
The first is incorrect because a unicellular organism is composed of just one cell. By definition, it cannot have specialized cells.
The final two answers are incorrect because all organisms — unicellular and multicellular — need to balance factors such as water and temperature.
