Protein digestion begins in the stomach, and this is a “preparation stage” compared to the events that occur in the duodenum. The presence of food in the stomach stimulates G cells of the mucosa of the gastric antrum and proximal duodenum to produce and release the hormone gastrin into the bloodstream
That would be C. yy
This is also known as the law of segregation of alleles(Mendel’s law of segregation). So Y and y are separated from each other in meiosis(specifically anaphase 2).
The possible gametes are RY, ry, Ry, rY
(C. The dinosaurs became extinct after the Cretaceous time period, after living on Earth for about 165 Million Years
The answer is myosin. Myosin are contractile protein the makes up thick filament. The molecule consists of a tail and two myosin heads which bind to myosin binding sites on actin molecules of thin filaments during muscle contraction. Actin on the other hand are contractile proteins that are the main component of thin filament. Each actin molecule has a myosin-binding site where myosin head of thick filament binds during muscle contraction.
Answer:
The papillary layer of the dermis is most closely associated with <u>Stratum Basale</u> layer of the epidermis.
Explanation:
Fibers like collagen and elastin that make up the papillary layer create a loose mesh because this layer is formed of connective tissue of the areolar that is loose. Dermal papillae, which resemble fingers, are formed when this surface of the dermis extends further to stratum basale of something like the epidermis. Columnar basal cells, which are continually dividing and also being forced forward towards the surface, may be found in this layer. Additionally, melanocytes that create melanin (the pigment that gives colour to skin) reside inside the stratum basale.
The various layers of the epidermis regularly regenerate due to epidermal stem cells. . Our hair follicles are constantly renewed because of hair follicle stem cells.
