The best material to use is foam, since it is the best insulator. An insulator will help slow the transfer of heat from outside of the lunchbox to inside of the lunchbox. The extra layer will be of foam.

Explanation:

If we compare the specific heat capacity of rubber and foam it can be found that foam has high specific heat capacity, which indicates that it is the good insulator.

An insulator is a substance in which heat exchange between medium and surrounding is very low.

Jayla and her grandma wanted their food to be cold all morning so foam as an insulator is the best choice.

Thus, high specific heat energy means large amount of energy required to raise the temperature by 1 degree in response to the mass of the substance as per unit mass.

What might account for the unusual results you obtained in the experiment in Part C? Select the two correct answers. Select the
irakobra [83]

Answer:

The correct options are B "The unusual F1 female is heterozygous for a reciprocal balanced translocation involving the chromosome with the apricot, bristle and clipped loci" and D "Independent assortment of non-compatible chromosome structures (i.e., translocated and normal chromosomes segregating together) in the F1 female led to the 90 eggs that aborted development"

Explanation:

The unexpected results obtained earlier can be attributed to the two factors listed above. At the time when meisois takes place, there is the process of independent assortment which leads to formation of zygotes. Due to the event of translocation, the eggs produced lacked some critical development genes.

Leto [7]
<h2>A) option is correct </h2>

Explanation:

  • RNA is a linear polymer of ribonucleotides
  • Sugar in RNA is ribose instead of deoxyribose which is present in DNA
  • The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
  • RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
  • Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix
