When did the early forms of life exist?
1.5 billion years ago
2.5 billion years ago
4.5 billion years ago
3.5 billion years ago
Where is the first form of life seen?
microfossils
layers of rocks
oceanic crusts
sediments
Which of the following is the first photosynthetic organism to form?
cyanobacteria
algae
fungi
gymnosperm
Which is not true about the prokaryotes?
They are simple in structure, small, and unicellular.
They do not have nucleus.
They survive in extreme conditions.
They are not capable of making their own food.
Which of the following processes brought changes in the early atmosphere?
Earthquake
Extreme condition
Photosynthesis
Volcanic eruption
The following are multicellular organisms first evolved from colonial aggregates except:
fungi
protozoans
sponges
mollusks
Which of the following statements is not correct?
Photosynthetic organisms decreased the amount of oxygen in the atmosphere.
Organisms change over time because of adaptation for survival.
Multicellular organisms evolved from unicellular eukaryotes.
The earliest forms of life were the prokaryotes.
All the following statements are true about the evolution of multicellular organisms except:
They are formed from multicellular colonial aggregates through cell specialization.
They are believed to have evolved from single-celled prokaryotes.
The process of continuous specialization brought more complex organisms.
The single-celled organisms that formed multicellular aggregates were like the cells of algae.
Why do you think the emergence of plants and animals came later than simple living organisms?
They are too big and take time to form.
They are the least important factor in the environment.
Their cell structures are more complex.
They contain more nucleus compared to lower forms of organisms
Considering the present condition of the environment, do you think living organisms are still evolving today?
No, because the environment remains favorable to living organisms.
Yes, because humans continuously alter the environment that triggers evolution among living organisms to survive.
Yes, because it is a natural phenomenon which we cannot stop from happening.
No, because there is no condition outside their bodies that will trigger evolution
