Convection occurs in the Earth. Convection currents in the magma help power plate tectonics.
A) Mr. Greenjeans needs a control group for comparison.
B) Mr. Greenjeans should use corn and radish seeds as a comparison.
C) Mr. Greenjeans should use three different types of pumpkin seeds.
D) Mr. Greenjeans probably should monitor the pumpkins for a longer period of time.
Mr. Greenjeans needs a control group for comparison.
How do we know that the fertilizer had any impact on growth since Mr. Greenjeans has no control group for comparison? He must know how the pumpkins will grow without any fertilizer as well. The control group gives us a way to compare the experimental groups to help form more valid conclusions.
Answer: The correct answer is C) it's phenotype.
Phenotype corresponds to the morphological form or physical appearance of an organism. It is depicted due to the genotype (genetic makeup) of the individual.
In other words, phenpti is related to the physical traits or specific characteristics of the individual.
Therefore, it describes how an organism looks (such as eye color, hair color, skin color).
Thus, C) is the right answer.
For n = 3, the possible orbitals are:
3s orbital: The 3s orbital is spherical in shape and can hold up to 2 electrons.
3p orbitals: The 3p orbitals have a dum/bb/ell shape and consist of three individual orbitals: 3px, 3p/y, and 3pz. Each of these orbitals can hold up to 2 electrons, so the total capacity of the 3p sublevel is 6 electrons.
3d orbitals: The 3d orbitals have complex shapes and consist of five individual orbitals: 3dxy, 3dxz, 3dyz, 3dx2-y2, and 3dz2. Each of these orbitals can also hold up to 2 electrons, resulting in a total capacity of 10 electrons for the 3d sublevel.
In summary, for n = 3, the possible orbitals are 3s, 3p (3px, 3py, 3pz), and 3d (3dxy, 3dxz, 3dyz, 3dx2-y2, 3dz2).

Answer:The n = 3 shell, for example, contains three subshells: the 3s, 3p, and 3d orbitals. There is only one orbital in the n = 1 shell because there is only one way in which a sphere can be oriented in space.
