Answer:
The cytoskeleton is a network of fibers that forms the "infrastructure" of eukaryotic cells, prokaryotic cells, and archaea. In eukaryotic cells, these fibers consist of a complex network of protein filaments and motor proteins that help move cells and stabilize the cell.
Explanation:
Function:
It helps the cell maintain its shape and provides support to the cell.
Various cellular organelles are held in place by the cytoskeleton.
It helps in the formation of vacuoles.
The cytoskeleton does not represent a static structure but is able to disassemble and assemble its parts in order to enable the internal and overall mobility of the cell.
The cytoskeleton contributes to cell migration because cell motility is required for tissue construction and repair.
The cytoskeleton helps transport communication signals between cells.
In some cells, it creates cell bulges, such as cilia and flagella.
Cytoskeletal structure
:
The cytoskeleton is composed of at least three different types of fibers: microtubules, microfilaments, and middle filaments.
These fibers differ in their size, and the microtubules are the smallest and the microfilaments are the thinnest.
Ecological pyramids are graphical representations of the trophic structure of an ecosystem. Regarding these pyramids, check the incorrect alternative.
A) A pyramid is called a number pyramid when it tells you how many individuals there are at each tropic level.
B) The biomass pyramid can be inverted.
C) An energy pyramid can never be reversed.
D) The base of a pyramid is not always represented by the producer. E) A biomass pyramid represents the amount of organic matter found at each tropic level
C. is the wrong option. This is because it represented the energy fixed in each tropic level . it is never inverted because it flow upwards in the ecosystem. This energy reduces upwards the pyramid, it is largest at the base of the producers, and decreases in amount as it flow upwards from one organism at each trophic level to another. This is because each organism uses the energy for biological work
