The outer core of the earth is the only part of the earth that is made up of liquid.
<h3>What is the earth core?</h3>
The earth core is the center part of the earth that is the main source of generation of the earth's magnetic field.
There are different layers of the earth core which includes the outer layer.
The outer layer of the earth is 70 kilometres (3.1–43.5 mi) in depth.
This outer layer is the third layer of the earth and is made up of liquid.

Answer:
this figure shows a hierarchy of organism, the ones at the top are the more complex and therefore more evolved. Agree or disagree? why?
Agree
Reason being that the complexity of the highest hierarchy makes evolution to occur whereby different pedigree resulted from it to form lesser or smaller organisms
Explanation:
I actually think that as people progress through middle adulthood, they experience Senescence (primary aging) in the form of molecular and cellular changes in the body. In this process cells irreversibly stop dividing and enter a state of permanent growth arrest without cell death. The process plays roles in normal development, maintains tissue homeostasis, and limits tumor progression.
Answer:
The correct answer will be- by lowering the surface tension at air/liquid transition.
Explanation:
Pulmonary surfactant is the mixture of proteins and lipids produced by the type II epithelial cells.
The surfactant is selected into the alveolar sacs where the surfactant reduces the surface tension of the air/liquid interface to 1 mN/m. The lipid content of the surfactant called dipalmitoylphosphatidylcholine or DPPC forms a surface film which lowers the surface tension.
This power surface tension reduces the work of breathing and thus prevent the alveolar sac from rupture or collapse.
Thus, by lowering the surface tension at air/liquid transition is the correct answer.
