The given boundaries are convergent- North America and the Pacific, shearing force, destroys, slab-pull while second one divergent- mid Atlantic ridge, tension force, created, slab-push.
<h3>What are plate tectonic boundaries?</h3>
A plate boundary is a three-dimensional surface where the velocity (speed or direction) of one lithospheric plate relative to the adjacent lithospheric plate changes significantly.

The given boundaries are convergent- North America and the Pacific, shearing force, destroys, slab-pull while second one divergent- mid Atlantic ridge, tension force, created, slab-push.
Thus, these can fill in the table with information about the different types of boundaries.

Explanation:
I did not know what article you refer to but I know that there is an article with this question.
Answer:
Zooplankton - Animals (mostly microscopic) which drift freely in the water column.
Explanation: Zooplankton, small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Hope this helped!!
Organs , fins is the correct answer
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.
