The mechanism of contraction in smooth muscle is different from skeletal muscle in that the site of calcium regulation varies. In addition, in an isotonic contraction the muscle alterations in length and moves the load and the the muscle cell membrane is named the sarcolemma.
Answer:
1, 4, 5 are true. 2, 6, 7, 9 are not true. 3 and 8 are not known.
Explanation:
According to the information we have gathered from the vehicles sent to Mars and the data they collected and analyzed, "Minerals of types known to form in liquid water" on Mars. There is "abundant water ice" and also "dried-up river beds".These statements actually exist.
"Surface pools of liquid water" does not exist on Mars. "A network of straight-line canals", "cities built by an ancient civilization" and "frequent rainfall and snowfall" also do not exist on Mars according to the data.
We do not have any information to prove the existense of "underground pockets of liquid" and "microscopic life" but they are possibilities.
I hope this answer helps.
I think it would be religion. In my opinion, religion is one of the factors that shape the culture of many countries. However, in the modern times, religion had somehow hindered children's understanding about sexual development. They believed that it would encourage teens to engage in pre-marital intercourse. I think sex education should be emphasized to make teens understand the idea of engaging such activity. Giving the knowledge and possible consequences would allow children to understand that it should after marriage and not before it. Although, this would only apply to Christians. I also think that with the help of sex education children would understand why they should protect themselves from STDs and unplanned pregnancy.
<span>Losing as little as 10% of excess body fat can increase hdl cholesterol levels, reduce high blood pressure, and improve glucose tolerance. I believe this to be true because losing body fat in my head, would mean that your body would not "need" the calories that it did before that body fat was lost which means that you would naturally get healthier and all of your levels should also fall into a "healthy" zone.</span>
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.
