The right answer is ultrasound.


Ultrasound is an imaging technique that uses ultrasound. It is used routinely in human and veterinary medicine, but can also be used in research and industry.


Contrast ultrasound is one that uses a contrast medium. The contrast medium composed of microbubbles is injected into the bloodstream intravenously at the time of the ultrasound examination of the patient. The microbubbles of the contrast medium are highly reflective to ultrasound during ultrasound examination; thus making it possible to image the blood vascularization of the organs for diagnostic purposes.

How are the nature of genes expressed
Amiraneli [1.4K]
Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.
At any given time, the amount of a particular protein in a cell reflects the balance between that protein's synthetic and degradative biochemical pathways. On the synthetic side of this balance, recall that protein production starts at transcription (DNA to RNA) and continues with translation (RNA to protein). Thus, control of these processes plays a critical role in determining what proteins are present in a cell and in what amounts. In addition, the way in which a cell processes its RNA transcripts and newly made proteins also greatly influences protein levels.

The runner below has a mass of 55 kg and is moving at 3.87 m/s. what is his kinetic energy in joules
sweet-ann [11.9K]

Answer:

<h2>411.86 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 55  \times  {3.87}^{2}  \\  = 27.5 \times 14.9769 \\  = 411.86475

We have the final answer as

<h3>411.86 J</h3>

Hope this helps you
