Answer: The correct answer is-
C.They replaced carbon dioxide with oxygen in the atmosphere.
Cyanobacteria ( also known as blue green algae) is a large phylum of bacteria that is capable of synthesizing its own food using carbon dioxide and water in the presence of sunlight ( photosynthesis).
They contain a green pigment called chlorophyll that absorbs energy from sunlight and helps in the formation of food ( glucose). They release oxygen as a byproduct in the atmosphere.
As these organisms utilize carbon dioxide ( that is present in the atmosphere) to give oxygen in return, therefore, they affected early atmosphere of Earth by replacing carbon dioxide with oxygen.
Thus, option C) is the right answer.
Answer:
Intestines
Explanation:because if you don't have them then you will not survive because you need them to go number one and number two if youndont then you will blow up your belly.
Answer;
A) Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic.
Explanation;
-Inductive reasoning is a logical process in which multiple premises, all believed true or found true most of the time, are combined to obtain a specific conclusion.
-The inductive method starts with many observations of nature, with the goal of finding a few, powerful statements about how nature works (laws and theories). In the deductive method, logic is the authority.
Overproduction
Most species produce more offspring than can survive.
Competition
Since living space and food are limited, organisms must compete for the necessities.
Variation
Differences between individuals in a population.
Adaptations
Any kind of inherited trait that improves an organism's chances of survival.
Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.
Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
A. The oceans.
That is because oceans absorb more than a quarter of the carbon dioxide that humans produce.
Hope that helped.
