The respondent is required to click on the circle, which corresponds to the desired answer. A dot in the middle will appear once an answer is chosen. Only one answer can be chosen.

For example, HIV infects a limited range of human leucocytes. This is because its surface protein, gp120, specifically interacts with the CD4 molecule—a chemokine receptor—which is most commonly found on the surface of CD4+ T-Cells. This mechanism has evolved to favour those viruses that infect only cells in which they... | {"source": "wikipedia", "start_index": 0, "docstore_id": "96453"} |
The third chapter contains examples of quadratic irrationalities as solutions and coefficients. The fourth chapter shows how these irrationalities are used to solve problems involving polygons. | {"source": "wikipedia", "start_index": 0, "docstore_id": "89852"} |
All quadratic equations have exactly two solutions in complex numbers (but they may be equal to each other), a category that includes real numbers, imaginary numbers, and sums of real and imaginary numbers. Complex numbers first arise in the teaching of quadratic equations and the quadratic formula. For example, the qu... | {"source": "wikipedia", "start_index": 0, "docstore_id": "113427"} |
Equations can be classified according to the types of operations and quantities involved. Important types include: An algebraic equation or polynomial equation is an equation in which both sides are polynomials (see also system of polynomial equations). These are further classified by degree: linear equation for degree... | {"source": "wikipedia", "start_index": 0, "docstore_id": "71015"} |
In two variables the non-zero quadratic forms are classified as: x 2 + y 2 {\displaystyle x^{2}+y^{2}} – positive-definite (the negative is also included), corresponding to ellipses, x 2 {\displaystyle x^{2}} – degenerate, corresponding to parabolas, and x 2 − y 2 {\displaystyle x^{2}-y^{2}} – indefinite, corresponding... | {"source": "wikipedia", "start_index": 0, "docstore_id": "38439"} |
This potential energy guides ATP synthesis via complex V (ATP synthase), which conflates ADP with another P to create ATP by pushing protons (H+) back into the matrix (this process is known as oxidative phosphorylation).

In infinite groups, such an n {\displaystyle n} may not exist, in which case the order of a {\displaystyle a} is said to be infinity. The order of an element equals the order of the cyclic subgroup generated by this element.

One important factor for sibling detection, especially relevant for older siblings, is that if an infant and one's mother are seen to care for the infant, then the infant and oneself are assumed to be related.

For instance problem 19 asks one to calculate a quantity taken 1+1/2 times and added to 4 to make 10. In other words, in modern mathematical notation we are asked to solve the linear equation: 3 2 × x + 4 = 10. | {"source": "wikipedia", "start_index": 0, "docstore_id": "145299"} |

For example, consider a line running through points (2,8) and (3,20). This line has a slope, m, of ( 20 − 8 ) ( 3 − 2 ) = 12. {\displaystyle {\frac {(20-8)}{(3-2)}}=12.} One can then write the line's equation, in point-slope form: y − 8 = 12 ( x − 2 ) = 12 x − 24. | {"source": "wikipedia", "start_index": 0, "docstore_id": "104420"} |
If B = 0 {\displaystyle B=0} in the original equation, the resulting line x = C A {\displaystyle x={\tfrac {C}{A}}} is vertical, and cannot be written as y = f ( x ) {\displaystyle y=f(x)} .
