Cosmos was a popular television science documentary series. Episode 7 titled "The Clean Room", explored the work of Clare Patterson and during said episode, as he awaits the sample from the spectrometer, Patterson proceeds to give thanks for the advancement of science by those who have come before him.
Patterson states that he wishes to give thanks to scientists who have come before him and proceeds to mention names such as:
- J. J. Thomson.
- Ernest Rutherford
- Harrison Brown
- Charles Lyell
- Michael Faraday

The presence of a mutant lac repressor that could not bind lactose would result in no transcription even when lactose was present because the mutant repressor would remain bound to the lac operator
The transcription of lac operator is controlled by the lac repressor. When lactose is present, the lac repressor normally will bind to the lactose, removing itself from the lac operator so it could be transcripted.
In this case, the mutation makes the lac repressor keep binding to the lac operator so the result would be no transcription even when lactose present.
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.
hope this helps
