Pampas and Patagonia
The Pampas are prolific South American marshes that comprise more than 750,000 km2 and combine the Argentine territories of Buenos Aires, La Pampa, Santa Fe, Entre Ríos and Cordoba. The vast fields are a common region, suspended only by the low Ventana and Tandil hills, near Bahia Blanca and Tandil Argentina, with an elevation of 1,300 m (4,265 ft) and 500 m (1,640 ft), sequentially.
Patagonia is a sparsely populated area at the southerly end of South America, administered by Argentina and Chile. The district encompasses the southerly segment of the Andes hills and the sands, pampas, and meadows to the east. Patagonia is one of the rare areas with shores on three oceans, with the Pacific Ocean to the westward, the Atlantic Ocean to the east, and the Southern Ocean to the South land.
Answer:
Since the gene mutates at a rate of 0.76 base pairs every 17.1 million years, to find out the time it would take for 1 base pair to mutate can be calculated by dividing 17.1 million years by 0.76
17,100,000 ÷ 0.76 = 22.5 million years
The following equation can be used to describe this:
μ = [(r2/N2) − (r1/N1)] × ln (N2/N1) = (f1 − f2) × ln (N2/N1)
r1 = the observed number of mutants at time point 1
r2 = the observed number of mutants at the next time point
N1 and N2 are the numbers of cells at time points 1 and 2
Hope that answers the question, have a great day!
Answer:
From the given information, the transport of glucose in blood across the red blood cells takes place by facilitated diffusion, that involves the spontaneous passive-transport with the help of trans-membrane proteins or transporter proteins to move the ions or molecules down the concentration gradient.
While the transport of glucose in intestines take place via active transport mechanism. It takes place from gut into intestines. It occurs against the concentration gradient with the help of energy molecules like proteins.
Diverticula Are Tiny Herniations Of The Mucosa Through The Colon Walls, A Condition Named Diverticulosis. They Are Believed To Form When The Diet Lacks Bulk And The Volume Of Residue In The Colon Is Small. The Colon Narrows Contractions Of Its Circular Muscles And They Become More Potent, Increasing The Pressure On Its Walls. Diverticulitis Is A Condition In Which The Diverticula Become Inflamed. Mrs. Ironfield Has Diverticulitis Due To The Inflammation Of Her Diverticula, As Shown By The Pain And Mass.
Psoriasis is a skin disease that manifests itself in symptoms of varying severity. It is a chronic disease that can not be cured but can be alleviated by many treatments (like chemotherapy).
Photochemotherapy: also called P-UVA. It consists of the combination of UVA (a type of UV light) radiation after the local or oral administration of a psoralen that acts as a sensitizing photo. It is used alternately in patients for whom UVB (another type of UV) has no effect, as P-UVA is more effective and longer-lasting, but is associated with basiloma (basal cell carcinoma) and melanoma.
