The capacity to an extracellular fluid that allows water to flow into or out of cells via the process of osmosis is known as tonicity.. Tonicity is a measure of its the osmolarity. A closer look at the hypotonic solution can assist in understanding this more.
The glandular epithelium comprises a set of tissues that is not the epithelium that covers and lines that is specifically designed to secrete and produce of different macromolecules. Due to its primary role it is often referred to as"the secretory epithelium.
The stratified cuboidal epithelium is composed of multiple layers of cells, in which the topmost layer is composed of cuboidal cells, while the lower layer could be columnar or cuboidal. In the case of stratified squamous epithelium cells in the layers below may differ from the epithelium on top. The alteration of cells that line the apical surfaces is based on the position and purpose of the epithelial tissue. The epithelium is extremely uncommon and only occurs in a few areas of the body.
The p-value, or estimated probability represents the most reliable probability of providing the lowest amount of significance, that the null hypothesis isn't the case.
The simple columnar epithelium, which is one type of epithelium, is made up of a single layer consisting of long, elongated cells. These cells are located in areas where absorption or secretion are the primary functions.
Simple diffusion is one of the types of passive transport that is, as the name implies is the simple movement of solute that happens when the electrochemical potentials of one side of the permeable barrier differ.
Facilitated diffusion is the method of biological transport where certain biomembrane structural components interact with specific solutes or classes of solutes significantly increasing the speed that they cross the membrane.
The study of embryology, also known as embryos, is a key element of evolution in biology and can identify the commonalities and differences between different species. The embryo of an organism refers to the fertilized egg that it progresses through the stages of development, which are unique to the particular species.
A pseudostratified columnar epithelium an epithelium made up of only one layer of cells which creates the appearance of multiple layers due to the nuclei in the cells are located at various levels. It is histologically an epithelium that is simple, even though when viewed from a cross-section it could appear as an epithelium stratified. The pseudostratified epithelium composed of squamous or cuboidal cells is extremely uncommon, while the columnar epithelium that is pseudostratified occurs across the body.
In essence, Monera is a biological kingdom comprised of prokaryotes (particularly bacteria). It is made up of single-celled organisms without the true nuclear nucleus.
The term"transgenic plants" refers to plants whose DNA has been altered by genetic engineering. This implies that the genes of another species is introduced and then merged in the genome of the plants that alters the features of the genome originally.
Binary fission can be described as a kind of sexual reproduction in which one living cell, or organelle expands twice its size, and then splits into two identical cells, which means that each of the daughter cells can be expected to grow to what size as the organelle or cell.
Platyhelminthes is a triploblastic, bilaterallysymmetrical, dorsoventrally-flattened, acoelomate, flatworms without an organ grade of construction. However, it has a Protonephridial exretory system and mesenchyme that fills the space between various organs.
Nematodes (Gr. nema thread+ form) are often referred to by various names, such as threadworm, non-segmented roundworm or pinworm. They are distinct from flatworms and higher segmented anelids.
Molluscs, also known as mollusks, are soft-bodied, symmetrical, segmented and coelomate mammals. They are usually shelled with a mantle.
Ctenophores, which are transparent, jelly-like and free-swimming marine animals, have biradial symmetry, comb shaped ciliary plates for locomotion, and lasso cells. However, nematocytes are lacking. They are also called comb jellies or sea walnuts.
The Arthropods belong to the bilaterally symmetrical metamerically separated, triploblastic creatures with a coelom that is diminished and altered. Their body is externally covered in an exoskeleton made of chitin that is molts regularly as well as their appendages joined.
Hemichordata (Gr., hemi, half; chorde, cord) means they are 'half' of 'part' chordates, a fact that is disputed. They are generally vermiform single, or colonial enterocoelous coelomate species with an intra-epidermal nerve system as well as a pre-oral, with or without gill-slits, and without the typical Nephridia.
