Our ancestors only eat what they needed. They did not splurge, or take their girl friends out on dinner dates for fries and greasy meals. They hunted and they dined in the driest and roughest of places. The CroMagnons, as beautful and naked as they were, because a symbol of humanity towards the future.

Answer:
The mutations in a genome similar to printing a book.
Explanation:
Every letter in a book resembles the mutations in the genome. errors that appear in one copy can be copied to all other copies of the book. Like printing errors, mutations always negatively affect the final product. Just as a single book is printed at a time, a single mutation is read at a time. Though mutations are not always negative and can help in the survival of the species when selection pressures change.
Answer:
Each cell can receive and respond to signals that they get from their surroundings. The three stages involved in transduction are reception, transduction, and response.
Reception: It involves receptor molecules and inducers. Receptors can be intracellular or extracellular. Receptors like G- protein-coupled receptor, receptor tyrosine kinase, and signaling molecules are the items that come under reception.
Transduction: In transduction, signals are transferred from outside of the cell to the inside of the cell. Secondary messengers are majorly involved in signal transduction like cAMP, cGMP, IP3, Ca2+, nitric oxide, etc.
Response: The response of cell signaling includes processes like protein synthesis, cell division, cell growth, etc.
