Answer: adaptive immune response

Explanation:

Autoimmune disorders are caused by different microoorganism and drug which manipulates the immune system in a way that immune system become unable to recognise between self antigen and foreign antigen. In that case immune system treats foreign antigen as self antigen which cause systemic or organ specific damage.

The exact cause of autoimmune disorders is unknown and hence it is  thought that it is caused by adaptive immune response which builds against self antigens and causes damage to the cells.

Hence, some autoimmune disorders are thought to be caused by adaptive immune response.

"The total concentration of receptors in a sample is 10 mM, and the concentration of free ligand is 2.5 mM. Calculate the percen
Mice21 [21]

Answer:

16.66 %

Explanation:

The receptors that are bound with the ligand can be calculated by the formula as follows:

Kd = [R] [L]/[RL]

Here, Kd is dissociation constant = 1.5 mM

R is free receptor concentration = 10 mM

L is free ligand concentration = 2.5 mM

The values needs to be constitute to find the percentage  of receptors that are bound to ligand.

Put all the values

1.5 = 10 × 2.5 / RL or RL = 25 /1.5

So RL = 16.66

Hence 16.66 % of receptor is bound to substrate.

Thus, the answer is 16.66%

(Marine science) The Atlantic puffin feeds on several species of Atlantic fish. A population of puffins living on Matinucus Rock
mariarad [96]

If another predator, that is more efficient hunter, enters the territory of the puffins, the puffins will find themselves in a very tough situation. They will either have to adapt very quickly, or die out.

The evolutionary pressure will be there fro the puffins to push them in a direction to adapt and be netter hunters, thus fight for their existence. That would mean that the puffin's beak, but also their speed and efficiency will have to improve in order to compete or even out-compete the new predator.

If the puffins do not manage to adapt relatively quickly, and a food shortage occurs, than they will die out, as they will lose the fight for food constantly.
