All of their functions are performed by a single cell.
Explanation:
Unicellular are those organisms whose body is madeup of one cell. In Unicellular organisms one cell perform all the functions and activities of the cell such as respiration, digestion, excretion and reproduction. Unicellular organisms reproduce asexually such as binary fission, budding and fragmentation etc. In Unicellular organisms, a single cell is divided into two equal parts and each part becomes a new organism.
Fascia, the type of tissue that "invests" the body structure, is the Connective tissue
Answer:
D. light bulb is the most appropriate answer
Explanation:
In an electric circut, presence of light bulb would convert the electric energy (flow of electrons) into light energy (photons). It will also resist the flow because to glow a bulb, electric energy will be required. This principle is also applied to all home based appliances where electric energy is used for several purposes.
Up to some extent, flow of electric energy in copper wires will also result in the loss of energy in the form of heat which is due to natural resistance of metal atoms.
Answer:
Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.
Explanation:
Flu vaccinations <u>reduce the risk of flu illness by over 50%</u>. This makes this process extremely important and fundamental for all human beings as they <u>not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people</u>, especially children and older adults who possess a greater risk of developing flu complications.
<u>The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell</u>. However, if a person has not been vaccinated, <u>the virus will attack the healthy cells</u> because there is an absence of antibodies that prevent this process.
