<span>Els moduladors al·lostèrics que actuen en els humans són el 2,3-Bisfosfoglicerat (2-3-BPG),el CO2 i els H+ . El 2,3-BPG s'uneix al centre del tetrà mer de l'estat T i així l'estabilitzà launió per interaccions iòniques. Els protons actuen perquè quan el pH és baix l'hemoglobinadisminueix la seva afinitat per l'oxigen (efecte Bohr). L'augment de la concentració del CO2 té el mateix efecte perquè el CO2 es combina en H2O i es dissocia en HCO3-i H+ i per aixòdisminueix l'afinitat de l'hemoglobina perquè augmenta la concentració de protons</span>

The main dietary factor associated with elevated blood cholesterol is?
Korolek [52]

The main dietary factor associated with elevated blood cholesterol is saturated fat.

<h3>What about saturated fat?</h3>
  • Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke).
  • Cholesterol that is circulated in the blood.
  • The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat.
  • Even if they include fat, foods derived from plants never contain cholesterol.
  • Only foods from animals do. Low density lipoproteins are able to transport cholesterol.
  • Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood.
  • Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.
  • When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.

Select all the potential effects of damming a river.
bonufazy [111]

The answer is; C & E

Building a dam alters the water regime down the dam. The dam also affects fish migration along the river, alters the transportation of sediments by the river downstream, and changes temperatures within the local environment of the dam. These changes, however, the subtle effect the ecosystem around the dam and down the river. The potential energy of the water held by the dam is, however, high and used to produce more electricity.

Suppose that the string of A nucleotides following the inverted repeat in a rho-independent terminator was deleted but that the
eimsori [14]

Answer: is seen below

Explanation:

Termination will not take place if the strings of A nucleotides following an inverted repeat of rho- independent termination ( which forms an hairpin structure)were deleted. Although, RNA polymerase may pause briefly at the hairpin, the presence of A- U base pairs is needed to destabilize the DNA - RNA interaction and to end transcription. If the string A nucleotides is not present, then transcription of RNA polymerase will continue.
