Biology technical

Studying the origin of life requires understanding how and why certain chemical reactions within inorganic matter could be capable of producing life. This is a cross-disciplinary study, encompassing portions of biology, chemistry, and physics. 

What is the main idea?

• the type of study

• origin of life

• chemical reactions related with life

The “RNA world” theory states that life may have begun with molecules of RNA (Ribonucleic acid), which are able to perform self-replication and catalyze reactions. Over time, these molecules evolved to become more complex.

What molecules does the last sentence refer to?

• RNA

• CHON

• catalyze reactions

If Miller-Urey had not performed the experiment to prove Oparin's theory, the theory would not have been accepted.

What kind of conditional is?

• Third

• Zero

• Second

The experiment, conducted by chemists Stanley Miller under the supervision of Harold Urey, revealed that the spontaneous production of organic molecules was possible under the oxygen-deprived conditions Oparin and Haldane suggested Earth may have been under at the time of life's origin.

In which voice is the paragraph written?

• Active

• Passive

• Infinitive

How else is the origin of life named?

• Genesis

• Previous life

• Biogenesis

Proposes that life arose from inorganic matter mixed with other compounds (known as the primordial soup) under an oxygen-deprived (reducing) atmosphere and gradually evolved into more complex organisms over time. 

• RNA theory

• Oparin-Haldane

• Panspermia theory

The deep-sea vents theory involves deep-sea hydrothermal vents, which are geologic structures that spew molecules that have abundant hydrogen.

What does involves refer to?

• refer something

• cover something

• include something

Panspermia theory states that life may have begun elsewhere in the universe and brought to Earth via microorganisms present in a meteor or some other method of transportation.

Who is the subject in the sentence?

• Oparin-Haldane

• The theory

• A meteor

The theory of panspermia says that if a meteorite falls on a planet, life will be generated.

Which conditional is used in the sentence?

• First

• Second

• Third

Which is the most accepted theory of origin of life?

• Spontaneous theory

• Oparin - Haldane

• RNA
