ELS 2nd Quarter - Quiz #1 (Module 1-3)

What are the three theories of concept of life? EXPLAIN each theory.

Answer explanation

Divine Creation

Spontaneous Generation

Parmspermia

The oldest fossil found aged around 3.4 billion years ago, this fossil is said to be without nucleus and measures about 5 to 25 micrometers in diameter. Given that time with low level of Oxygen gas, this organism may not require Oxygen in order to survive. What kind of organism is this?

• Aerobic

• Fossil

• Stromatolites

• Anaerobic

This is the process used by prokaryotic cells wherein they produce energy by stripping the electron from mineral

• Anaerobic

• Biochemical Processes

• Photosynthesis

• Chemical Processes

Over many years, cell growth and sediment deposition formed dome-shape, layered structure called stromatolites. It is said that this organism uses photosynthesis resulting oxygen to accumulate in the air and water. How can you prove that this organism uses photosynthesis based on the statement?

• Because it produces Oxygen gas resulting it to accumulate

• Because it uses energy from the sun

• Because of its domed-shape layered structure

• It cannot be proven

Base on the module, cyanobacteria, an organism that uses photosynthesis to produce life made two huge positive impact in the presence of life on earth, what are these?

Answer explanation

Ozone Layer

New Environment

Give at least one eukaryotic gene that resembles with Archeal or Bacterial genes. Indicate if this gene is either archeal or bacterial.

The scientist that conducted an experiment to test the idea of spontaneous generation that a vital component from air was necessary for life to exist.?

• Needham

• Pasteur

• Redi

• Spallanzani

In doing his experiment that is related spontaneous generation, this scientist did not practice aseptic technique?

• Needham

• Pasteur

• Redi

• Spallanzani

Which among the following scientist formulated the “Germ Theory” after doing the experiment to disproved spontaneous generation?

• Needham

• Pasteur

• Redi

• Spallanzani

Which among the following scientist conducted an experimentation using an aseptic method boiled a broth which contain meat and vegetables placed in a clean glass container, now both containers were boiled but one set-up was not sealed, allowing air to enter the flask, which had disproved the theory of spontaneous generations?

• Needham

• Pasteur

• Redi

• Spallanzani
