3) Choose the correct answer. Which best describes the complex organization in an organism?
Cells are the basis of everything and independently operate the system.
Cells are organized into tissues that make up organs and create organs systems. These
work together in order to keep an organism healthy and well.
Every organism has a different type of organization and it is not possible to establish a
pattern.
Organ systems make up tissues and cells.
Tissues make up cells and organs make up tissues.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
