The model below shows the Moon at one position in its orbit around Earth. The white half of the Moon represents the part of the
Furkat [3]

Answer: Although the Moon appears to shine, it does not emit light. Instead, we can see the Moon because it is lit up by the Sun.

Explanation:

The part of the Moon that is both sunlit and facing Earth is called the Moon's phase.

As the Moon orbits Earth, the Moon's phase changes. The model below shows the Moon's phase at eight positions in its orbit. The smaller moons closer to Earth show where sunlight hits the Moon. The larger moons farther from Earth show how the Moon will look during that phase.

Firewood is made up of cellulose, which is a polymer of glucose molecules. When burning, heat and light are given off, indicatin
skelet666 [1.2K]

Answer:

Exergonic reaction

Explanation:

  • A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.
  • An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
  • The energy that is released in the exergonic reaction is usually observed  in the form of heat and light.
  • The energy is released due to the breaking of the chemical bonds.
  • Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.

What are the functions of the three major forms of RNA (ribosomal RNA, messenger RNA, and transfer RNA)?
vovangra [49]

Answer:

Ribosomal RNA: Structural part of ribosomes

Messenger RNA: Carry genetic information from DNA to proteins

Transfer RNA (tRNA): Transport amino acids to protein synthesizing complex.

Explanation:

Ribosomes are made up of ribosomal RNA (rRNA) and proteins. The catalytic activity for the formation of peptide bonds between amino acids during protein synthesis resides the RNA of ribosomes.  

Messenger RNA (mRNA) is formed by the process of transcription during which the nucleotide sequence of the template DNA strand is copied into that of the RNA. The mRNA serves as a template for protein synthesis. The nucleotide sequence of mRNA is read in the form of genetic codes to specify the amino acid sequence of a protein. In this way, the genetic information stored in DNA is carried to the proteins.

During the process of protein synthesis, tRNAs carry amino acids to the mRNA-ribosome complex so that the amino acids are incorporated into the polypeptide. For the purpose, there is a tRNA with a specific anticodon sequence for a particular amino acid.
