The species is the smallest among all group; it has only one
kind of organism. Through to the system
developed by Linnaeus, each organism is given a two-part scientific name that
consists of a genus name and a specific name. The words used for scientific
names are from the Latin and Greek languages. They sometimes seem difficult to
read and even harder to pronounce. Since the different species of organisms
number in the millions, it is necessary for scientists around the world to have
a common language to be able to identify any organism with accuracy. As you
know, people in different countries have different names for organisms. This
naming system prevents confusion.
2. Falling sea levels and colliding continents created connections between continents that led to great movements of land animals during the Neogene Period is the correct statement.

Answer:
Microfilaments, Intermediate filaments and microtubules
Explanation:
Three distinct elements make up the cytoskeleton in eukaryotic cells are:
1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell, intracellular transport, maintaince of the cell shape..
2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…
3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins), formation of the axoneme of cilia and flagella, formation of the mitotic spindle.

virus. Other symptoms of this virus are jaundice (yellow eyes and skin, dark urine), pain in
your belly, loss of appetite, nausea, fever, diarrhea and fatigue. </span>A vaccination against
