The right answer is to perform photosynthesis (more precisely to convert ADP to ATP by ATP synthase).
Light comes to us in the form of photons. These photons have a different energy potential depending on their wavelength.
When a pigment picks up a photon corresponding to its absorption capacity, one of its electrons goes into the excited state. This energy can be transmitted in 3 ways: either by spreading it in the form of photon or heat; both ways lose energy. The third is to transmit resonance energy and there is almost no loss of energy.
A photosystem consists of a reaction center and a collector antenna to optimize the absorption of photons triggering photochemical reactions in order to operate the ATP synthase to produce ATP in the presence of a hydrogen gradient.

Functional magnetic resonance imaging (fMRI) is the neuromarketing technique that looks for active areas in the brain by measuring the amount of oxygenated blood flowing through the body.
Functional magnetic resonance imaging (fMRI) is a noninvasive technique for measuring the activities of the brain. This technique is used to observe the brain’s functional anatomy as it reveals the parts of the brain that are involved in a certain mental process. fMRI functions by using magnetic resonance imaging to measure the small changes in blood oxygenation and flow that take place as a result of activities of nerve cells in the active areas of the brain.
We know that Hardy-Weinberg conditions include the following equations:

where 
And where p = dominant, and q = recessive; this means that
is equal to the homozygous dominant,
is the heterozygous, and
is the homozygous recessive .
So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of
or 0.04. Let that equal our
value.
So when we solve for q, we get:


Now that we have our q value, we can use the other equation to find p:



So then we can solve for our heterozygous population:

This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:

So now we know that there are 32 heterozygous cats in the population.
