stiks02 [169]

Answer: Identical to its parent.

Explanation:

The cloning can be defined as the process by which genetically identical individuals of an organism is produced either artificially or naturally.

The cloning in case of biotechnology refers to the creating the clones of organisms or copies of cells or DNA of the parent cell that is being used in the process.

The parent cell is cloned and numerous copies is made just like that of the asexual reproduction in the nature.

Example: Dolly the sheep.

Describe Newton's Law of Viscosity and the constitutive behavior of non-Newtonian fluid
CaHeK987 [17]

Answer:

- "Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers".

- A non-Newtonian fluid is a fluid which the relationship between the shear stress and the velocity gradient is not properly defined by the Newton's viscosity law, thus, the behavior is not lineal but potential.

Explanation:

Hello, here the answers:

- "Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers" (taken from Kundu, P. K., Cohen, I. M., & Dowling, D. R. (2012). Fluid mechanics.), thus, it means that when you have a fluid with an acting-on-it share stress (an external force which move the fluid), the related velocity gradient (variation or change in velocity) at which the layers are moving are related as:

\pi =-v \frac{du}{dy}

Whereas \pi is the shear stress, v is the viscosity and the differential accounts for the change in the velocity in the arbitrary y coordinate.

- A non-Newtonian fluid is a fluid which the relationship between the shear stress and the velocity gradient is not properly defined by the Newton's viscosity law, thus, the behavior is not lineal but potential, based on:

\pi =-v (\frac{du}{dy})^n

Whereas n accounts for a decreasing or increasing behavior of the shear stress.

Best regards.

38.25 grams of silicon is combined with 14.33 grams of nitrogen gas. How many grams of silicon nitride can be formed if nitrogen
REY [17]
Since it is stated that nitrogen is the limiting reactant (sometimes called limiting reagent), you only have to worry about the amount of nitrogen since we know that there is excess silicon.
Since this is a stoichiometry question, the first thing to do is turn the mass of nitrogen gas into moles by dividing the mass of nitrogen gas by its molar mass.  (14.33g)/(28g/mol)=0.5118mol nitrogen gas.  Then you have to convert moles of nitrogen gas to moles of silicon nitride by using the fact that 2 moles of nitrogen gas turn into 1 mole of silicon nitride (i got that ratio from the chemical equation given).  (0.511mol N₂)x(1mol Si₃N₄/2mol N₂)=0.2555mol Si₃N₄.  Know you just need to find the mass of silicon nitride by multiplying the number of moles of silicon nitride by its molar mass.  (0.2555mol)x(140g/mol)=35.85g
Therefore the amount of silicon nitride produced from this reaction 35.85g.

I hope this helps
