In frogs, different mating seasons are a barrier to reproduction.
We feel hotter in summer than in winter because the temperature is generally higher than in winter.
<h3>
What are seasons?</h3>
There are three seasons on earth namely winter, summer, and rainy season. In the winter season, the temperature is cold and during summer the temperature is higher.
Timing and characteristic of season depend upon the location of the earth. The time of a year region experience season depends on it is northern hemisphere or southern hemisphere.
The southern hemispheres experiences winter while northern hemisphere experiences summer. The cycle of seasons is caused by earth's tilted towards the earth. The planet rotates around an axis.
Therefore, We feel hotter in summer than in winter because the temperature is generally higher than in winter.

Answer:
Temperature is an essential aspect in any experiment as it can affect the various variables of the experiment. It can affect the result and outcomes of an experiment as per the interaction various molecules shows with the temperature.
In molecular biology related experiments that deals with the protein related experiments are also effected by the temperature as enzymatic reactions are slow on low temperature and proteins are also act like enzymes. On high temperature protein may lead to increase in collisions of the molecules of protein and fasten the enzymatic reaction and may lead to degrade the protein.

Hope this is helpful! Sorry if my answer is choppy.
Explanation:
Biotic and abiotic features are both important in ecosystems because for example, a biotic factor like a plant, relies on an abiotic factors like the rain and the sun. If the rain were non existent, then the plants would no longer be alive causing a chain reaction in the food system. Biotic factors like plants and animals that are non existent can also cause negative effects in biomes and ecosystems.
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.
