masha68 [24]

Answer:

\mathbf{cummulative \ incidence = \dfrac{60}{1000}}

Explanation:

We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.

Mathematically:

\mathbf{cummulative \ incidence = \dfrac{New \ cases \ of \ disease \ occurrence}{Number  \ of \ population \ at \ risk \ at \ onset}}

Given that:

Number of the population at risk = 1000 individuals

New cases during Jan 1 - Dec 31 = 60 because;

At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:

∴

\mathbf{cummulative \ incidence = \dfrac{60}{1000}}

Troyanec [42]

calcium is released into the sarcoplasm through gated channels

<h3>What is calcium ?</h3>

The chemical element calcium has the atomic number 20 and the letter Ca as its symbol. Calcium is an alkaline earth metal that reacts with air to create a black oxide-nitride coating. Its heavier homologues barium and strontium are most similar to it in terms of physical and chemical characteristics. It is the third most plentiful metal, behind iron and aluminum, and the fifth most abundant element in the crust of the Earth.

The most prevalent calcium component on Earth is calcium carbonate, which may be found in limestone and the fossilized remains of ancient marine life. Other calcium-rich materials include gypsum, anhydrite, fluorite, and apatite. The word "lime" comes from the Latin word calx, which was made by heating limestone.

Tju [1.3M]
<span>look at each perspective on how the phenomenon might have took place in a different kind of perspective. Multiple approaches are explored to see which condition fits and answers the query the most -accurate and reliably.

developing a technique for observing an object that has yet to be observed


</span>Thus, to achieve the creative approach above the researchers must utilize and apply the scientific method in gathering, interpreting and analyzing empirical evidence. 

<span>Empirical evidence, data or knowledge is an obtained set of facts or figures or existing and presenting data that was yielded during the process of experimentation or scientific discovery. These empirical data or evidence is further studied and investigated by the scientist in a formal scientific approach which follows the steps of observation, making a hypothesis, gathering data, interpreting data and evaluating the data. These steps of the scientific approach are vital in the course to explain and discuss the result and evidence obtained during the process.
