What are the differences between mitosis and meiosis in human cells? Pay particular attention to the types of cells, number of d
Nezavi [6.7K]
Mitosis Involves one cell division? Results in two daughter cells Results in diploid? daughter cells? (chromosome? number remains the same as parent cell) Daughter cells are genetically identical Occurs in all organisms except viruses Creates all body cells (somatic?) apart from the germ cells? (eggs and sperm) Prophase is much shorter No recombination/crossing over occurs in prophase. In metaphase individual chromosomes (pairs of chromatids) line up along the equator. During anaphase the sister chromatids are separated to opposite poles. Meiosis Involves two successive cell divisions Results in four daughter cells Results in haploid? daughter cells (chromosome number is halved from the parent cell) Daughter cells are genetically different Occurs only in animals, plants and fungi Creates germ cells (eggs and sperm) only Prophase I takes much longer Involves recombination/crossing over of chromosomes in prophase I In metaphase I pairs of chromosomes line up along the equator. During anaphase I the sister chromatids move together to the same pole. During anaphase II the sister chromatids are separated to opposite poles. Similarities Mitosis Diploid parent cell Consists of interphase, prophase, metaphase, anaphase and telophase In metaphase individual chromosomes (pairs of chromatids) line up along the equator. During anaphase the sister chromatids are separated to opposite poles. Ends with cytokinesis. Meiosis Diploid parent cell Consists of interphase, prophase, metaphase, anaphase and telophase (but twice!) In metaphase II individual chromosomes (pairs of chromatids) line up along the equator. During anaphase II the sister chromatids are separated to opposite poles. Ends with cytokinesis.

AVprozaik [17]

<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

  • The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
  • Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

  • All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
    A semipermeable lipid bilayer makes up the cell membrane.
  • The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

  • The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
  • second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
