Question

1. which theory suggests that life originated near underwater volcanic vents?

a) primordial soup theory
b) panspermia
c) hydrothermal vent theory
d) rna world hypothesis

1. the belief that life arises spontaneously from non - living matter is known as:

a) spontaneous generation
b) biogenesis
c) panspermia
d) endosymbiosis

1. which of the following is not an advantage of multicellularity?

a) larger size
b) increased complexity
c) specialization of cells
d) decreased need for coordination

1. the rna world hypothesis proposes that:

a) rna played a central role in the early evolution of life
b) dna was the first genetic material
c) proteins were the first catalysts for life
d) life originated on another planet

Explanation:

• Question 3: Hydrothermal Vent Theory posits life originated near underwater volcanic vents.
• Question 4: Spontaneous generation is the belief life arises from non - living matter.
• Question 5: Multicellularity requires coordination, so decreased need for coordination is not an advantage.
• Question 6: RNA World Hypothesis says RNA was central in early life evolution.

Answer:

1. C. Hydrothermal Vent Theory
2. A. Spontaneous generation
3. D. Decreased need for coordination
4. A. RNA played a central role in the early evolution of life
