Globally, man made radiation takes up 21 percent of all radiation.
The correct answer is: a feedback mechanism.
The bionic pancreas is bio-engineered device used for the regulation of blood sugar levels in order to maintain body homeostasis. The bionic pancreas includes a sensor that monitors blood sugar levels and sends a signal to a separate device that will then release the appropriate hormone into the bloodstream to return blood sugar levels back to normal. This device is very functional because of its ability to dose insulin and glucagon based on continuous sugar blood measurements.
Answer:
The following step is to sterilize the wire loop, turn the plate 90 degrees, collect some organisms from the first area and continue to streak on the second area. Repeat for the third area.
Explanation:
The goal of three-phase streak is to obtain <u>isolated colonies</u> in the plate. To do this, the culture is diluted by spreading it through the entire plate.
In the <em>first phase</em>, one third of the plate is used to streak the initial <u>inoculum</u><u> </u>in a zig-zag motion. As the wire spreads, the densitiy of organisms diminishes and colonies start to be further apart. Doing this only one time, is usually not enough to obtain isolated or separated colonies. So two more phases are used.
Before the <em>second phase</em>, the wire is sterilized, and colonies are collected by passing through the first area two or three times, so the inoculum now is much smaller than at the beginning. The organisms are spread in the second third of the plate, also in a zig-zag motion.
The same process is repeated in the <em>third phase, </em>by filling the remaining area of the plate.
By doing this, it is very probable that the initial culture is diluted enough to obtain single, isolated colonies in the plate which can then be grown separately in order to identify them.
Answer:
Uracil (U) is a nitrogenous base found only in RNA but DNA is deprived of it. In DNA Thymine is found. in DNA adenine (A), guanine (G), thymine (T) and cytosine (C) are present. whereas uracil replaces thymine in case of RNA.
Answer: so the cycle of energy in the earth all depends on the different types of tropic levels in the ecosystem, or maybe even the use of solar power.
The plants as well they have energy in them that spreads to the earth. The photosynthesis process also helps it go through it
