The maximum activity level of a particular enzyme is 606060 micromolars per minute \left(\dfrac{\mu\text{m}}{\text{min }}\right)( min μm start fraction, mu, m, divided by, m, i, n, end fraction, )and occurs at a temperature of 202020 degrees celsius (^\circ\text c)( ∘ degree, c, ). for every 2\,^\circ\text{c}2 ∘ c2, space, degree, c above or below 20\,^\circ\text c20 ∘ c20, space, degree, c, the enzyme activity decreases by 8\,\dfrac{\mu\text{m}}{\text{min}}\ ,8 min μm 8, space, start fraction, mu, m, divided by, m, i, n, end fraction, space. which of the following equations can be used to find the temperatures, ttt, at which the enzyme activity level is 40\,\dfrac{\mu\text{m}}{\text{min}} 40 min μm 40, space, start fraction, mu, m, divided by, m, i, n, end fraction ? choose 1 60-4|t-20| =40

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

girl imma just put my comment here because i need a couple point okurrttt

you didnt put any of the following

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
