Answer: Mutualism
Explanation: Fungi have a lot of mutualistic relationships with other organisms. When we say mutualism, both organisms benefit from this relationship. A common example of a mutualistic relationship involving fungi is the mycorrhiza, a mycorrhiza is a mutualistic relationship between a fungus and a plant.
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.
Since this is movement that is occurring against the natural movement from high to low concentration, this is Active transport.
The option C.
The nurse can give the following instructions:
1. the procedure will most likely last for ten minutes
2. since it is still an infant, the child will be put under anaesthesia
3. a pulsed dye laser treatment will be given
4. if general anaesthesia will be given, then there are special rules for eating and drinking restrictions before procedure

Correct option a) Increased plasma volume.
A potential negative health effect of stress is Shrinks the brain. Stress that's the left unchecked can contribute to many health problem, such as high blood pressure , heart disease , obesity and diabetes.
The volume of the brain tends to remain about the same, it has been found that chronic stress in healthy individuals can causes areas of the brain associated with emotions , metabolism and memory of that individual to be shrink slowly.
Stress can also be positive which is distress , getting job promotion or being given grater responsibilities keeping us alert and ready to avoid danger. It can became negative if a person faces continuous challenges without relief or relaxation between challenges.
