Which of the following molecules found within the cell membrane is thought to be involved in cell self-recognition? a. carbohydr

Nadusha1986 [10]

Answer:

Lipids

Explanation:

Membrane mostly considered largely of lipid bilayer. It is the double called phospholipids. These glycolipids contains the chain of fatty acids. These fatty acids determines that whether the sheet of membrane is formed around the vesicles or not.

Lipids that provide a liquid to the membrane cells. The consistency of liquid appears as the light oil. It consists of fatty acid chain that includes many fatty acid molecules for example oxygen that permeate from the membrane. These fatty acids repels large molecules fatty acids such as sugar, electrical charged ions etc.

How is the ideal mechanical advantage of a wheel and axle calculated?

kvasek [131]

Mechanical Advantage is the value which tells us the factor by which the machine is able to convert the force applied to it to its output.

Ideal Mechanical Advantage of wheel and axle is calculated by

IMA = Wheel Radius / Axle Radius

By virtue, the higher the computed IMA the lower the force needed to be exerted, this is the purpose for using machine, lower input force but larger output. (The smalled the axle radius compared to the wheel radius is the better setup.)

Consider 2 steel rods, A and B, B has three times the area and twice the length of A, so young modulus of B will be what factor

AVprozaik [17]

Answer:

$\frac{Y}{Y_o}$ = 2/3

Explanation:

The yuong modulus of a rod is defined as the relationship between the tensile strength and the strain

Y = $\frac{ \frac{F}{A} }{\frac{\Delta L}{L_o} }$

let's use the subscript "o" for rod A

I = $\frac{ \frac{F}{A_o} }{ \frac{\Delta L}{L_o} }$

tells us that rod B has

A = 3 A₀

L = 2 L₀

we substitute

Y = $\frac{ \frac{F}{A} }{ \frac{\Delta L}{L} }$

Y = $\frac{ \frac{F}{3A_o} }{ \frac{\Delta L}{ 2L_o} }$

y = ⅔ $\frac{ \frac{F}{A_o}}{ \frac{\Delta }{L_o} }$

substituting the value of Y₀

Y = ⅔ Y₀

$\frac{Y}{Y_o}$ = 2/3

Which part of the manufacturing process involves heating and rolling blocks of steel into flat sheets and bars?

faltersainse [42]

A. Forming

Explanation:

Metal forming is a metallurgical process which involves heating and rolling blocks of steel into flat sheets and bars.

Metal forming is the process of working metals and utilizing its properties to form different shapes.

Metal forming is made possible by metallic bonds in metals.
The bulk of the physical properties of metals can be attributed to these bond types.
In metal forming, metals are shaped into different substances.
Metal forming preserves the mass of the metallic body and the shapes modified by force.
