Which statements describe how traits are inherited? Check all that apply. ●An offspring always recieves different alleles from each parent.
●An offspring always recieves the same alleles from each parent.
●An offspring can recieve different alleles from each parent.
●Traits are inherited when proteins are passed from parents to offsprings.
●Traits are inherited when genes are passed from parents to offspring.

ANSWER:
C. An offspring can recieve diffrent alleles or the same alleles from each parent.
D. Traits are inherited when genes are passed from parents to offspring.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

the force required to move the cart is divided by three or 33.33 n.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
