Answer:
The correct answer will be option-False.
Explanation:
Spermatogenesis or formation of sperm cells in humans takes place in two stages: cellular division called "spermatocytogenesis" and metamorphic changes in spermatids to spermatozoa called "Spermiogenesis".
The mitotic and meiotic cellular division produces round spermatids which undergo much physical change during the process called Spermiogenesis. During Spermiogenesis spermatids modify themselves for fertilization like acrosome cap formation, tail development and nuclear condensation.
Thus, option-false is the correct answer.
Small proteins released from tissue cells infected with viruses, as well as from activated lymphocytes and macrophages, are called Interferons
<h3>What are Interferons ?</h3>
A collection of signalling proteins known as interferons are produced and released by host cells in response to the presence of certain viruses. Typically, a virus-infected cell will release interferons, boosting the antiviral defences of neighbouring cells.
- They are released by infected cells, where they trigger the innate immune system's production of cytokines as well as natural killer cell activity and antigen presentation.
- By establishing cytokine barriers, interferons shield uninfected cells from subsequent viral infections. Additionally, they prevent cellular division and control the organism's immune response.

Answer:
The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.
