The products for photosynthesis are sugar (C6H12O6) + oxygen (6O2)
The letter should contain concerns about the causes and ill effects of erosion.
<h3><u>Explanation</u>:</h3>
Sir,
I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.
The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.
So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.
Thanking you,
XYZ.
Answer: Individuals with a high concentration of cysteine in their urine, show symptoms of cystinuria.
Explanation:
Cystinuria is an hereditary and rare disease in which stones of an amino acid called cystine form mostly in the kidney but also in the ureter and bladder. This is a dimeric amino acid which is formed by two cysteine molecules linked by a disulfide bond. L-cysteine is a non-essential sulfuric amino acid found in a wide variety of foods, some of which are proteins. <u>This condition is passed from parents to children so it is hereditary, the person must inherit the defective gene from both parents. </u>
Cystinuria is caused when there is a high concentration of cystine in the urine. Normally, most cystine dissolves, enters the kidneys and returns to the bloodstream. <u>However, people with cystinuria have the genetic defect that interferes with this process. </u>This condition is due to a defective transport of cystine in the apical membrane of the intestinal epithelium and proximal renal tubule. The result is an absence of cystine reabsorption in the renal proximal tubule producing an excess of cystine in urine and with the consequent formation of kidney stones. Cystine stones are very difficult to remove by lithotripsy unlike the rest of the stones. Therefore, a non-invasive therapy should be carried out to prevent the recurrence of stone formation. This therapy would be based on a high intake of liquids, alkalization of urine, and use of chelating agents. In order to preserve kidney function, a combination of these three therapeutic measures is necessary to reduce both the recurrence and the morbidity of the disease.
The independent variable of an experiment is the one that is intentionally changed or manipulated to see the results of changing said variable.
We are told that in each different group, the amount of caffeine that is given to the dogs changes - in the control group, they get no caffeine, in the 2nd group, they get 10 mg of caffeine each, and in the 3rd group, they get 50 mg of caffeine each.
Therefore, since the amount of caffeine that is given to the dogs is the only variable that is being manipulated, this is the independent variable.
Answer:
Characteristics of epithelium tissue
1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)
2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.
4.Avascular– Epithelium typically lacks its own blood supply.
5.Regeneration– Epithelium cells can regenerate if proper nourished.
6.Absence of nerves (except for a few axons in the deeper layers)
Classification scheme of epithelial tissue:
Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.
