The correct answer is "Redwood tree; human being; Paramecium; White Blood Cell; Escherichia coli; Chickenpox virus; Ribosome; Prion fibril; Water molecule; Sulfur atom".

Explanation:

Redwood trees are gigantic trees, and its size can reach up to 90 meters.

The average size of a human being is 1.7 meters for males and 1.6 meters for females.

Paramecium are members of the protozoa genus, among the largest unicellular algae. Its average size is among 50 to 330 micrometers.

White Blood Cell are up to 17 micrometers in diameter.

Escherichia coli is a type of bacteria, as a prokaryotic organism is much more smaller than a eukaryotic cell such asa the white blood cell. Escherichia coli is up to 2 micrometers in diameter.

Chickenpox virus are among the largest viruses, they are from 150 to 200 nanometers in diameter.

Ribosomes vary on size depending if they are Prokaryotic or Eukaryotic, where the first are up to 20 nanometers and the second are up to 30 nanometers.

Prion fibrils are aggregates comprised of several protein units. It size varies depending on the number of proteins, but the ones containing around 200 units can reach up to 27 nanometers.

Water molecule is comprised of two atoms of oxygen and one atom of hydrogen, its size is measured with picometers (1 picometer is equal to 1000 nanometers). A water molecule has a size of 275 picometers.

Sulfur atom is the smallest in the list. Its size is around 100 picometers.

These penguins are all members of the species Aptenodytes patagonicus. What is the difference between a species and a population
Vikki [24]

Answer:

A species refers to the group of similar organisms that can interbreed to produce a viable offspring. For example, <em>Homo sapiens </em>is a species of humans, <em>Panthera leo </em>refers to the species of lions et cetera.

In contrast, a population in ecology refers to the group of organisms of the same species living in a particular area. For example, the deer population in a forest, human population in a town et cetera.

For example, <em>Aptenodytes patagonicus </em>refers to a species of penguins but number of penguins of the same species living in a particular area would make up a penguin population of that area.
