Answer:
The image has your answer :)
Explanation:
Significant evolution, in Darwin's opinion, moves much too slowly to be seen in a person's lifetime. Recent biological tests have demonstrated that some populations may develop extremely quickly, with significant changes happening over many generations in the lab.
What role does Darwin's theory of evolution play?
- Charles Darwin, a scientist of the 19th century, investigated the idea of natural selection. Natural selection provides an explanation for how a species' genetic features might evolve through time. This might result in speciation, or the creation of a new, separate species.
- The genesis and adaptations of species entered the scientific canon with Darwin's finding of natural selection. The adaptive characteristics of creatures might now be explained by natural processes, much as the occurrences of the inanimate universe, without the need for an Intelligent Designer.

The function of the nucleolus is: D. Assembly of ribosomes.
The function of the nucleolus is to transcribe DNA into ribosomal RNA and assemble RNA into ribosomal subunits. The creation of RNA is important because RNA makes up ribosomes which are responsible for protein synthesis in the cell.
Answer:
Steroid hormones
Explanation:
Steroid hormones are the second largest groups of hormones. They are made up of small cholestrol units and are fat soluble, therefore they can pass easily through cell membranes.
Function:
They have roles in many vital functions of our body such as salt and water balance, formation of sexual traits,immunity related functions,metabolism and improving health by withstanding injuries.
Mode of action:
- Steroids being hormones can effect the processes of body in two ways: They affect the transcription of genes involved in synthesis of certain proteins- this is called genomic level action.
- They can affect by binding with specific membrane receptors like G-proteins, Ion channels and transporters- non genomic level function. Through these ways, they can affect many mechanisms occurring inside the cell.
Hope it helps!
I believe that is called the epigenome!
Good luck!
