Answer:

-Animal communication is context driven—they react to stimuli, or indexes and Humans can talk about remote, abstract, or imaginary things that aren't happening in their immediate environments.

-Any gender of human can use the same languages but in the animal world only some species can speak between the same gender

-The way that animals communicate are biological, or inborn but Humans need to acquire language —words must be learned.

Arrange according from largest to smallest in size:
Inessa [10]

Answer:

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.

▪️Chapter - The fundamental unit of life
Rashid [163]

Answer:

The difference between Prokaryotic cell and Eukaryotic cell are;

\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or}    & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \  membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell
