The diagram models a cross-section of rock from a certain region. The life form represented by the fossil in rock layer 1 is not present in any of the layers above it. What is the most likely explanation for this?
A.
The life form only recently moved to the region.
B.
The life form became extinct in the region long ago.
C.
The life form only recently evolved.
D.
The life form evolved into all of the species in the next layer.

The correct answer is c. orbital shape. "the angular momentum quantum number l describes the shape of an orbital. it corresponds to each orbital type, i.e. (0,1,2,−1)=(s,p,d,f,g,"

A1 a 2 a 3 ooh lol i think that's it

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
