Question 5 unsaved a scientist in a lab looks under a microscope at muscle tissue and makes a few observations on what he notices. looking at the scientist’s observations below, which one best supports the cell theory? question 5 options: the muscle tissue cells contain multiple mitochondria. the cells in the muscle tissue are undergoing mitosis. each cell contains more than one nucleus. none of the above.

The muscle tissue cells contain multiple mitochondria.

Explanation:

Hello,

Cell theory's statements and research have shown that in a typical cell, there are more than 1000 mitochondrias, this accounts for the continuous cell's working. At first glance, we can't know whether the cell is undergoing mitosis since no information is given about it and the cell theory just explain the cell's structure. In addition, a typical cell has just one nucleus.

Best regards.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
