Which stament about energy is mostly correct

1 answer:

6 0

I would say C is the most correct.
In D it depends on what water source you're using. Let's say it is a waterfall, then the source of the water (melting ice or a lake) may disappear in the future.
If you're using underwater "windmills" placed in the ocean, then you would expect it to last a while as the ocean will not disappear in the near future.

Which ligand binds the tightest? Ligand A, with a Kd of 10^-9M Ligand B, with a Kd of 10^-3M Ligand C, with a percent occupancy

padilas [110]

To answer this item, we must take note that the ligand that binds the tightest is the one with the lowest dissociation constant, Kd. Kd's for both A and B are already given so, we only need to solve Kds for C and D.
Kd of C
0.3 = (1x10⁻⁶)/(1x10⁻⁶ + Kd) ; Kd = 2.3x10⁻⁶
Kd of D
0.8 = (1x10⁻⁹)/(1x10⁻⁹ + Kd) ; Kd = 2.5x10⁻10
Since Ligand D has the least value of dissociation constant then, it can be concluded that it binds the tightest.

An unknown rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g what is this substance

tino4ka555 [31]

The rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g substances density will be 1.20 centimeter cube.

<h3>What is density?</h3>

The density of any substance is the ratio of the mass of substance to the volume of the substance and the unit will be centimeter cube.

The volume of the substance will be 3.60cm high × 4.21cm long ×1.17cm wide = 17.7 milliliters.

density = mass of substance / volume of substance

Substituting the value in formula

Density = 21.3g / 17.7 milliliters.

Density = 1.20 centimeter cube.

Therefore, rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g substances density will be 1.20 centimeter cube.
