Answer:
Fermentation
Explanation:
I think there is a typo in the question as it doesn't make sense to breakdown oxygen - do you mean the proces of breaking down sugar?
Fermentation vis a type of anaerobic respiration, meaning it occurs in the absence of oxygen. It occurs when sugar is broken down into ethanol and carbon dioxide. It is used to produce alcoholic drinks like beer and wine, and in the production of bread.
The correct answer is option (a) Scanning tunneling microscope.
Microscopes are used to see the objects at molecular level. Scanning tunneling microscope( STM) is a type of optical microscope that uses optics(light) and lenses to see the enlarged size of the object. This microscope use a small metal tip under a high voltage. when this tip of microscope is brought close to the metal, the metallic tip of microscope draws electrons from the atom (metal) to be observed. This generates an electric current. There is a computer system attached to the microscope that detects the change in the electric current. Computer plots the change in position of atoms in metal.
The last common ancestor of gymnosperms and angiosperms possessed the same characters such as pollen, seeds, and vascular tissue.
<h3>What are angiosperms and gymnosperms?</h3>
The gymnosperms are a group of plant that are known as seed- producing plants such as Ginkgo, gnetophytes, cycads etc.
Angiosperms are the plant that produces flowers and having seeds enclosed within their fruit.
Gymnosperms have no production of flowers and fruits and they contain seeds without cover on the surface of their leaves.
Therefore,last common ancestor of gymnosperms and angiosperms possessed the same characters such as pollen, seeds, and vascular tissue.
