Humans are eukaryotes. Eukaryotes are organisms whose cells have a true nucleus containing their genetic material, while prokaryotes do not have a nucleus. Human cells, like all other animals, plants, fungi, and protists, are eukaryotic cells. **

No, eukaryotes are not necessarily endothermic animals. Eukaryotes are a broad group of organisms that have cells with a nucleus and other organelles, including animals, plants, fungi, and protists. Endothermic animals, on the other hand, are animals that can regulate their body temperature internally, such as mammals and birds. While some eukaryotic organisms like mammals are endothermic, many others, such as plants and fungi, are not. **

Eukaryotes are organisms whose cells have a true nucleus, which contains their genetic material. They also have other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum. Examples of eukaryotes include plants, animals, fungi, and protists. Prokaryotes, on the other hand, are organisms whose cells do not have a true nucleus or other membrane-bound organelles. Their genetic material is located in the cytoplasm, and they are typically smaller and simpler in structure compared to eukaryotic cells. Examples of prokaryotes include bacteria and archaea. **

Gene regulation in eukaryotes refers to the mechanisms that control the expression of genes. This process allows cells to carefully regulate when and how much of a particular gene is transcribed into RNA and translated into protein. Gene regulation is essential for the proper functioning and development of an organism, as it allows cells to respond to internal and external signals and adapt to changing conditions. This regulation can occur at various levels, including transcriptional, post-transcriptional, translational, and post-translational levels. **

Prokaryotes are single-celled organisms that lack a distinct nucleus and other membrane-bound organelles. Their genetic material is located in the cytoplasm in the form of a single circular chromosome. Eukaryotes, on the other hand, are organisms whose cells contain a distinct nucleus and other membrane-bound organelles. Their genetic material is organized into multiple linear chromosomes within the nucleus. Eukaryotes can be single-celled or multicellular organisms and include a wide range of organisms such as plants, animals, fungi, and protists. **

No, eukaryotes are not exclusively warm-blooded animals. Eukaryotes are a broad category of organisms that includes both warm-blooded (e.g. mammals and birds) and cold-blooded (e.g. reptiles, amphibians, and fish) animals, as well as plants, fungi, and protists. Warm-blooded animals, also known as endotherms, are able to regulate their body temperature internally, while cold-blooded animals, or ectotherms, rely on external sources of heat to regulate their body temperature. **

Transcription in eukaryotes involves several steps. First, the DNA double helix unwinds at the gene site to expose the coding region. Then, an enzyme called RNA polymerase binds to the promoter region of the gene and begins to synthesize a complementary RNA strand using one of the DNA strands as a template. As RNA polymerase moves along the DNA strand, it adds complementary RNA nucleotides, creating a pre-mRNA molecule. This pre-mRNA undergoes further processing, including the removal of introns and addition of a 5' cap and a poly-A tail, before it is ready to be translated into a protein. **

One can watch old TV shows online by subscribing to streaming services like Netflix, Hulu, or Amazon Prime Video, which often have a library of older TV shows available for streaming. Another option is to check if the specific TV show is available for purchase or rental on platforms like iTunes, Google Play, or Vudu. Additionally, some TV networks have their own websites or apps where they offer a selection of old TV shows for free with ads. **
