Fatigue is typically one of the earliest symptoms of MS
Answer:
The cell is the small portion of living matter that constitutes the structural and functional unit of all living beings, formed by genetic material and cytoplasm and delimited by the plasma membrane that enables interaction with the environment.
Explanation:
All living beings are made up of basic units called cells; for this reason it is said that the cell is the structural unit of living beings. In the cell, all the functions and chemical reactions necessary for life are carried out; in addition, it participates in the reproduction processes. Different parts of the cell are distinguished, from the outside to its center. The fundamentals are: cell membrane (delimits and regulates), cytoplasm (organelles) and nucleus (DNA). The cell originates from a single cell, the egg or zygote, which occurs after the union of the gametes (ovum and sperm). Although many species of living beings are capable of reproducing without the participation of gametes, all in some generation do so through this mechanism. The cell is the simplest living being and, therefore, performs its three vital functions: nutrition (the function of uptake of matter and energy), relationship (the capture of stimuli and the emission of adequate responses) and reproduction. Cells have the ability to renew themselves either by growth or by reproduction, cell growth is limited to the manufacture of cellular materials, while reproduction allows the generation of new cells from existing ones. In unicellular organisms, new individuals originate; in multicellular cells, the number of cells increases, making possible the growth of the individual or the renewal of what had been damaged.

Secretary of Health and Human Services Alex Azar said he expects there to be enough vaccine doses starting in the second quarter of 2021 so that everyone can get it. Scientists also say that we will be wearing masks until 2022 or even longer, depending on people’s behavior. Masks and social distancing will become the norm for awhile even with a vaccine out and running.
hope this answered your question! :))
