Answer: C. Microfilaments
Explanation: Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell. Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell.
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
<span>The impurities that were removed include sodium hydroxide, ethanol, and the boiling stones.</span>
Hi there!
Meiosis is a type of reproduction where two divisions occur. It is when gametes, sex cells, divide. In prophase of meiosis, it is similar to that of mitosis, as in the spindle fibers develop as well as centrioles. First, homologous (pairs) of chromosomes line up in the center of the cell. Next, spindle fibers pull the pairs apart, leaving one chromosome of each pair on each side. Then, the nuclear material divides as the spindle fibers and centrioles go away. Lastly, the cytoplasm divides, leaving two cells. Meiosis two starts out with prophase again. In prophase, the DNA condenses and forms short chromosomes as well as spindle fibers and centrioles developing. Next, the chromosomes (there is only one chromosome, made up of two sister chromatids) line up in the center of the cell. Next, the spindle fibers pull the chromosomes apart, pulling one chromatid to each side of the cell. Then, the nuclear material divides and the spindle fibers and centrioles disappear. Lastly, the cytoplasm divides, leaving four cell in total.
Hope this helps!! :)
