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.
Answer;
-23 in males
In humans, 23 in males is the only homologous chromosome pair that isn't the same.
Explanation;
-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.
