Questions & Answers about Исследование результатов экспериментов проводится в лаборатории.

What is the grammatical role and case of Исследование in this sentence?

Исследование is a noun in the nominative singular, acting as the subject of the sentence. It means “a study” or “research.”

Why are результатов and экспериментов both in the genitive case?

They form a chain of genitive attributes:

• результатов (genitive plural of результат) modifies исследование, giving “research of the results.”
• экспериментов (genitive plural of эксперимент) further specifies “results of experiments.”

So the hierarchy is исследование (результатов (экспериментов)).

Why are there two genitives in a row? Could I swap their order to экспериментов результатов?

No. The order reflects the logical relationship: you study the results, which belong to experiments. Swapping them (экспериментов результатов) would read “experiments of results,” which is semantically backward and ungrammatical.

What does the suffix -ся in проводится indicate?

The -ся suffix marks the verb as passive (middle) voice. проводится is the third-person singular passive form of проводить, meaning “is being conducted.”

Can I rephrase the sentence in the active voice? How would that look?

Yes. In active voice лаборатория becomes the subject:
Лаборатория проводит исследование результатов экспериментов.
Here лаборатория is nominative, исследование is accusative (direct object).

Why is в лаборатории in the prepositional case? How would I say “into the laboratory” instead?

With в to indicate location (“where?”), Russian uses the prepositional case: в лаборатории = “in the laboratory.” To express motion (“into the laboratory”), you switch to the accusative: в лабораторию.

Is the word order fixed here? What if I start the sentence with В лаборатории?

Russian word order is relatively flexible for emphasis. Starting with В лаборатории—
В лаборатории проводится исследование результатов экспериментов.
—puts special focus on location but retains the same meaning.

Could I simplify исследование результатов экспериментов to исследование экспериментов?

You can, but it changes the nuance.

• исследование результатов экспериментов: you study the results of experiments.
• исследование экспериментов: you study the experiments themselves.

Where is the word stress in исследование and экспериментов?

• исследова́ние: stress on the “а” (fourth syllable).
• экспериме́нтов: stress on the “е” (third syllable).
