I believe it's "pollen".
When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.
Hope this helps!
Answer:
DNA contains genes that can be read to create <u>messenger RNA</u> that directs the <u>ribosome</u> to build certain <u>proteins</u> as needed by specific cells or situations.
Explanation:
DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.
Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.
<em>When a </em><u><em>cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized</em></u><em>.</em>
Answer:
Anabolism collectively refers to all the processes of chemical reactions that build larger molecules out of smaller molecules or atoms; these processes are also known as anabolic processes or anabolic pathways. Anabolic pathways use energy, while catabolic pathways release energy.

Translated into the amino acid sequence of a protein. amino acids – twenty molecules that are the building blocks of proteins.
