Answer:
I believe it is D.
Explanation:
Ecological succession has to do with how the habitat changes over time. So D would make the most sense.
In chemical reactions the substances present at the start of the reaction are reactant and the substances produced are called product
For radioactive materials with short half-lives, you use a very sensitive calibrated detector to measure how many counts per second it is producing. Then using the exact same set up you do the same at a latter time. You use the two readings and the time between them to determine the half-life. You don’t have to wait exactly a half-life, you can do the math with any significant time difference. Also, you don’t need to know the absolute radioactivity, as long as the set up is the same you only need to know fraction by which it changed.
For radioactive materials with long half-lives that won’t work. Instead you approach the problem differently. You precisely measure the mass of a very pure sample of the radioactive material. You can use that to calculate the number of atoms in the sample. Then you put the sample in a counter that is calibrated to determine the absolute number of disintegrations happening in a given time. Now you know how many of them are disintegrating every second. You use the following equations:
Decays per Second = (Number of Atoms) x (Decay Constant)
Half-life = (Natural Log of 2) / (Decay Constant)
And you can calculate the half-life
Hope it helps :)
Mark it as brainliest pls :)
Paliperidone has low affinity
for lipid-rich environments compared from the parent compound risperidone. Due to
its hydrophilicity characteristic, paliperidone is capable of hydrogen bonding
with other molecules containing water and hydroxyl groups. Lipophilicity is a
determining factor for the rate and degree of metabolism of the drug in the
body and for crossing the blood–brain barrier (BBB).
Moreover, these differences are
implicated in synaptic plasticity and neuronal firing effects in the mechanism
of mitochondrial movement, protein expression, and phosphorylation of the drug.
Paliperidone as a mood stabilizer is an active metabolite of risperidone with antipsychotic effects used
for the treatment of schizophrenia and its associated disorders.
