Answer:

Electron microscope

Explanation:

Electron microscope uses a beam of electrons as energy source. Since the beam has an exceptionally short wavelength, it strikes most objects in its path and increases the resolution of the microscope significantly. Thus it has a higher magnification and resolution.

Amino acids are processed by the liver. <br><br> Describe this process.
inessss [21]

Regulation of amino acids

When amino acids are absorbed by liver cells a series of chemical reactions begins. ... The amine group is reduced to ammonia by the addition of a hydrogen atom. This process is called deamination. The non-nitrogenous portion of the molecule is converted to carbohydrates or fats.

vivado [14]

I have attached lac operon model having 4 genes. See attachment for better understanding.

Answer:

The Lac operon is controlled  by two signals.

Initiation

Glucose and lactose  concentrations control the initiation of  transcription of the Lac operon through  their effects on the Lac repressor protein  and Cap.

Lactose absent (Repression)

When lactose is absent, the Lac  repressor binds the Lac operator and shuts  off expression of the operon.

Lactose present (Transcription)

Addition  of lactose increases the intracellular  concentration of a related compound,  allolactose. allolactose binds to the  Lac repressor, causing it to undergo a  conformational change that releases its grip  on the operator DNa.

Glucose absent (Repression)

When  glucose is absent, cyclic aMp (red triangle)  is produced by the cell and Cap binds to  DNA.

Glucose present (Transcription)

LacZ, the first gene of the operon,  encodes the enzyme b-galactosidase, which  breaks down lactose to galactose and  glucose.

Does anyone know how to graph this? Please help I’m desperate
erastova [34]

Answer:Hopefully you feel comfortable with what a number line is. A graph is two number lines (called the x axis and the y axis) which cross each other at zero. A linear equation is a relationship between the two number lines. So if I gave you the linear equation “y=x”, this means if you pick a number on the x axis, the equation tells you what the number is on the y axis. So if you picked x=10, then you would know y=10. You can then draw a point at the co-ordinate (10,10), the point is there to tell you that the equation is true at that point. You can then pick another x, say x=9, then you know y=9 and you can put a point at (9,9), so you know the equation is true at that point also. You can do this with any number that you pick for x, and if you did that for every number, all the points you draw would turn into a line.
