Amoeba sisters: video recap
cell transport
traveling molecules
for the following scenarios, determine whether the molecules in the scenario are moving by (s) simple
diffusion, (f) facilitated diffusion, or (a) active transport.
8. for water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels
known as aquaporins.
9. while water molecules are polar, they are also very small. one fact not mentioned in the video is that some water
molecules are able to squeeze directly through the phospholipid bilayer due to their small size.
10.
charged ions are traveling through a cell membrane with the concentration gradient.
_cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than
the concentration already stored in the cells.
at a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the
12.
cell.

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.

the correct answer is:

a. formation of precipitation

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
