Answer:
The correct answer is option - C. They replaced carbon dioxide with oxygen in the atmosphere.
Explanation:
Cyanobacteria or Blue-green algae is a group of bacteria that is making its own food using water and carbon dioxide in the presence of sunlight, the process of photosynthesis
These organisms release oxygen as a byproduct of photosynthesis in the atmosphere. Through this process, these organisms replaced carbon dioxide with oxygen in the atmosphere in the early earth.
Thus, the correct answer is option C. They replaced carbon dioxide with oxygen in the atmosphere.
Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get
Putting values in this equation, we get:
Thus, the object is moving with a velocity of 1.33 m/s
...The origin of life on Earth is a set of paradoxes. In order for life to have gotten started, there must have been a genetic molecule.. something like DNA or RNA—capable of passing along blueprints for making proteins, the workhorse molecules of life.
Well the whole point of the cell cycle is to make more cells so it could be C, but it also wants the daughter cell to have the same AMOUNT of DNA, not the exact type (in meiosis) so B may be right, but most likely it is C
Type of energy that can be sensed by the ears is sound energy.
A.
