The genotype for some with attached earlobes would be ee because unattached earlobes are dominant(EE or Ee) which means attached would be recessive(ee).

Answer: The genotype for the attached earlobes would be ee.

As per the question, unattached earlobes are dominant over attached earlobes ( recessive). A dominant trait is expressed when it has even one dominant gene ( determined by capital letter like Ee here)

On the other hand, a recessive trait is expressed only when the recessive gene ( determined by small letter) is present in the homozygous state ( like ee in this case).

As the attached earlobe is a recessive trait, therefore the only possible genotype for this is 'ee'.

A cube has a height of 8 cm and a mass of 457 g. What is its density?
ZanzabumX [31]

Answer:

the answer is b,  0.89

Explanation:

A cube has a height of 8 cm and a mass of 457 g. What is its density?

a. 233,984 g/cm

b.  0.89g/cm3

c. 1.12 g/cm3

Density = mass/volume

the volume of the cube is 8X8X8=512cm3

the mass is 457 gm

the density is 457/512 = 0.889 gm/cm3

the answer is b, 0.89

Explain the similarities and differences between putting a beaker of ethanoic acid in the refrigerator and mixing it with sodium
frez [133]

Answer:

See explanation

Explanation:

When a beaker of ethanoic acid is placed in the refrigerator, its temperature drops and the vessel feels cool.

Now, when we mix ethanoic acid and sodium carbonate, an endothermic reaction occurs, fizzing is observed as carbon dioxide is given off and heat is lost to the surroundings causing the reaction vessel to feel cool to touch.

The difference between putting ethanoic acid in the refrigerator and adding  sodium carbonate to the solution is that, in the former, no new substance is formed. The substance remains ethanoic acid when retrieved from the refrigerator. In the later case, new substances are formed. The substance is no more ethanoic acid because a chemical reaction has taken place.
