Answer:
D. The alleles that are passed from parents to offspring.
Explanation:
<em>The alleles that are passed from parents to offspring are what determine the Genotype of an organism since alleles contain hereditary and genetic materials within them.</em>
Half life formula
The number of unstable nuclei remaining after time t can be determined according to this equation:
N(t) = N(0) * 0.5^(t/T)
where:
N(t) is the remaining quantity of a substance after time t has elapsed.
N(0) is the initial quantity of this substance.
T is the half-life.
It is also possible to determine the remaining quantity of a substance using a few other parameters:
N(t) = N(0) * e^(-t/τ)
N(t) = N(0) * e^(-λt)
τ is the mean lifetime - the average amount of time a nucleus remains intact.
λ is the decay constant (rate of decay).
All three of the parameters characterizing a substance's radioactivity are related in the following way:
T = ln(2)/λ = ln(2)*τ
How to calculate the half life
Determine the initial amount of a substance. For example, N(0) = 2.5 kg.
Determine the final amount of a substance - for instance, N(t) = 2.1 kg.
Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.
Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.
If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.

Answer:
Mycorrhiza is a symbiotic association in between the green plants and fungus.
The micorrhiza are located in the roots of the vascular plants. The Green plants performs the process of photosynthesis and the sugars produced are supplied to the Micorrhizas.
The fungus supplies the nutrients, water such as phosphorus that is absorbed from the soil to the plant body.
