Elephants in musth often discharge a thick tar-like secretion called temporin from the temporal gland located on the temporal sides of the head. Temporin contains proteins, lipids (including cholesterol), phenol and 4-methyl phenol, [8] [9] cresols and sesquiterpenes (notably farnesol and its derivatives).
The forehead of the elephant is actually a structure that protects the pollen from the weather called a galea, and ranges in size from 1.5–3 millimeters, and extends into the long slightly coiled beak that resembles the elephant's trunk of 5–18 millimeters; the lateral lobes of the flower resemble an elephant's ears. This "remarkable ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
These are two different species, with African elephants belonging to the genius Loxodonta and Asian elephants belonging to the genus Elepha. These two creatures also exist in totally separate ...
Like elephants, Stegodon had teeth with plate-like lophs that are different from those of more primitive proboscideans like gomphotheres and mammutids. [1] Fossils of the genus are known from Africa and across much of Asia, as far southeast as Timor (with a single record in southeast Europe).
They are thought to have chewed differently from modern elephants, using an oblique movement (combining back to front and side to side motion) over the teeth rather than the proal movement (a forwards stroke from the back to the front of the lower jaws) used by modern elephants and stegodontids, [2] with this oblique movement being combined ...
Phospholipids [1] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. [2]
The limb bud is a structure formed early in vertebrate limb development. As a result of interactions between the ectoderm and underlying mesoderm, formation occurs roughly around the fourth week of development. [1] In the development of the human embryo the upper limb bud appears in the third week and the lower limb bud appears four days later. [2]
