Answer:
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom. In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation:
Diploblast organisms are the ones that have only two primary germ layers. These organisms have outer ectoderm and inner endoderm but no mesoderm. Example: Cnidarians
A true coelom is derived from mesoderm and is completely lined with tissue derived from mesoderm. The outer and inner linings of the coelom are made of muscle layers that are developed from the mesoderm.
A pseudocoelom is the one that is incompletely lined with mesoderm. Both pseudocoelom and a true coelom serve as shock absorber and provide space wherein the internal organs can be placed. The fluid present in them sere as medium for transport of nutrients, gases, etc.
1 bactericidal are solutions used to Kill micro organism by killing the cell walls. while in the other hand bacteriostatic agent is used to inhibit the growth of micro organisms by interfering with their cellular metabolism like replicating their DNA reproduction.
2 bactericidal decreases the number of bacteria in the body while the other does not rather it decreases the growth of it.
Answer:
The two prokaryotic domains are Archaea and Bacteria.
The eukaryotic domain is Eukarya.
Both prokaryotic and eukaryotic are similar in which they have a plasma membrane and cytoplasm; meaning all cells have plasma membrane surrounding them. A difference between Eukaryotic and Prokaryotic is that eukaryotic have organelles, for example, a nucleus. Prokaryotic cells do not have a nucleus.
Answer:
25nm
Explanation:
Microtubules are polymers of tubulin and they are part of the cytoskeleton. The roles of the microtubules are to maintain the shape and structure of the cell, intracellular transport, they are structural part of the cilia an flagella, they are involved in cell division etc.
Tubulin that is the basic unit of microtubules is composed of two globular proteins, alpha and beta tubulin. Alpha and beta subunits spontaneously form dimers which then assemble into oligomers, then in chains (protofilaments); that can form a variety of intermediate structures such as single and double rings or spirals. Protofilaments that associate side-by-side form sheets of protofilaments which then curle to form a tube or cylinder (closing of microtubule). Continued growth of microtubules occurs by the direct addition of more dimers on + side.
