Answer:
Hello!
Here's the correct order of events:
- Development of photosynthesis
- Free oxygen in the atmosphere
- Development of eukaryotic cells
- Sexual reproduction
Explanation:
Development of Photosynthesis:
3.5 billion years ago, the first photosynthetic bacteria emerged. They used near infrared light to form sulfates or sulfur compounds instead of oxygen.
Free oxygen in the Atmosphere:
Later, about 2.7 billion years ago, cyanobacteria or blue-green algae began to perform oxygenic photosynthesis by utilizing visible light.
Development of Eukaryotic Cells:
The first eukaryotic cell probably appeared around 2 billion years ago. The evolution of eukaryotes is explained by the endosymbiont theory. The endosymbiotic theory explains that eukaryotic cells formed when an ameoba like organism engulfed cyanobacteria and a microorganism capable of cellular respiration that later evolved into chloroplasts and mitochondria respectively.
Sexual reproduction:
The origins of sexual reproduction are still widely debated upon; some studies claim the event occurred 1.2-2 billion years ago.
The right option is; glucose + oxygen = carbon dioxide + water-Energy is produced in the form of ATP.
Cellular respiration is the process whereby molecules are broken down by cells for energy. In this process, glucose (a complex sugar) is combined with oxygen to form water, carbon dioxide, and energy in the form of adenosine triphosphate (ATP).
The chemical equation for cellular respiration is; C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36 or 38 ATP
. (1 glucose molecule + 6 oxygen molecules = 6 carbon dioxide molecules + 6 water molecules + 38 molecules of ATP). where glucose and oxygen are the reactants, while water, carbon dioxide, and energy (ATP) are the products.
Regent's Park, is trying to communicate the SCALE of the exotic animal by comparing it to the nine onlookers behind it. A scale is a unit used in mathematics.
<h3>What is a scale?</h3>
Scale is a characteristic of an object that does not change when it is multiplied by a given unit, thereby showing universality.
The units of scale in mathematics and physics include, among others, length and energy.
The value that is multiplied in a given scale is called 'common factor' and it is used to show universality.
