Answer:
<em>Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. </em>
Provides evidence of evolution and can classify species and find common relatives
Do you mean diagram A compared to Diagram D?
Diagram D is different from Diagram A because Diagram D shows representations of molecules which make up compounds. Diagram A is a representation of atoms which make up elements.
Answer:
<em>Yes, the above terms will be much similar.</em>
Explanation:
The term 'closest evolutionary relationship' reflects the organism or species which were the closest to different species in a phylogeny.
Most common ancestor also describes the ancestor from which two different organisms might have evolved.
Both the terms 'closest evolutionary relationship' and 'most common ancestor' show the common ancestors in a phylogenetic lineage. Hence, on evolutionary levels, both these terms have similar meanings and are often used to describe phylogenetic lineages.
Answer:
After a cell was treated with a certain chemical, the ribosomes stopped functioning. The cell activity immediately affected by this change in ribosome function is protein synthesis.
Explanation:
The basic structural units of all living things are known as cells. Inside the cells, specialized structures called ribosomes are present, which synthesize proteins. The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation.
The transcription process takes place in nucleus, where the information from a DNA strand is copied into a single stranded messenger RNA (mRNA) molecule using RNA polymerase enzyme. During the ending of transcription, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the ribosome, translation occurs where the genetic code in mRNA is read and protein is synthesized. These proteins are used by cells to perform important functions such as repairing cellular damage, maintain cellular structure, create hormones, cell division etc.
