There Are 4 Valence Electrons So do the one with 4 valence electrons
Because bacteria mutates that's why we have a new flu vaccine every year , because strains of DNA in the bacteria change all the time.
Plantae: Autotrophic, Multi- or Monocellular, have cell walls as well as a membrane, have a chloroplast making the characteristic green color and to capture sunlight for photosynthesis. Break down generated glucose into it's components.
Animalia: Heterotrophic, Multi- or Monocellular, have a cell membrane made of a phospholipid bilayer, and many mitochondria to aid with movement energy. Feed on plants or other animals. Eukaryotic cells.
Fungi: Heterotrophic, most Multicellular, have a rigid cell wall made of chitin, specialized cells to aid with decomposition of dead organic matter. Eukaryotic cells.
Protista: Can be plant-like, animal-like, or fungus-like. Most are single-celled, may be chemosynthetic or photosynthetic. Eukaryotic cells.
Archeabacteria: Prokaryotic. Do not have nuclei or membrane-bound organelles. Move around using a flagellum to propel itself. Lives in mainly fluid environments (air, water). Separated from Eubacteria due to it's high tolerance of extreme conditions, such as high salinity, no oxygen, burning heat, or freezing cold. Can be chemosynthetic or anaerobic, as well as aerobic.
Eubacteria: Normal, everyday bacteria. Prokaryotic, chemosynthetic, anaerobic, or aerobic. Do not have nuclei or membrane-bound organelles. Mobile using a flagellum to propel itself.
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also for efficient for these smaller and miniscule cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy.
The arc length is calculated by using the equation below:
Arc length = 2πr ( C/360)
where r is the radius and C is the central angle.
<span>Arc length = 2π(6) ( 65/360)
</span>Arc length = 6.81 inches
Therefore, the correct answer is option C.
