Explanation:
Options were missing from the question so the options are:
A.From the ice cube to the glass.
B. From the lemonade to the glass.
C. From the lemonade to the ice cube.
D. From the ice cube to the lemonade.
Answer: Option C
Explanation:
The main principle of heat transfer is that heat always flows from the hotter body to the colder body.
Here, the hotter body is thermos in which the lemonade was kept and the colder body is cooler in which the ice was kept.
During the mixing of lemonade into ice, the heat will from the hotter body to the colder body which means from lemonade to the ice. This process of heat transfer is unidirectional( hot body to cold body).
Hence, the correct answer is option C.

Answer:
The genetic information in DNA is carried to the cytoplasmic protein-manufacturing centers in form of mRNA.
Explanation:
The process of transcription forms RNA using the DNA template strand thereby copying the genetic information of DNA into the nucleotide sequence of mRNA.
The mRNA leaves the nucleus and enters the cytoplasm to join ribosomes. The nucleotide sequence of mRNA is read in the form of triplet codons to specify the amino acid sequence of the proteins.
In this way, mRNA serves as a carrier of the genetic information in DNA.
