Explanation:
Here's a quote:
“… as the earth and ocean were probably peopled with vegetable productions long before the existence of animals; and many families of these animals long before other families of them, shall we conjecture, that one and the same kind of living filaments is and has been the cause of all organic life.”

The correct answer is option D, that is, Jon is correct because the respiratory system removes waste from the body by ridding it of carbon dioxide when we exhale, and the digestive system removes waste from the body in the large intestine where the waste is sent and removed through the rectum.
The respiratory system functions to provide adequate oxygen for the proper functioning of the body and at the same time works to remove the waste products like carbon dioxide via the process of exhalation.
On the other hand, the function of the digestive system is digestion and absorption. It digests the food components into smaller pieces, and helps in the absorption of nutrients from the food, the leftover undigested food, or waste is excreted out through the rectum. Hence, both respiratory and digestive system exhibits one common function of excretion of waste materials.
False, Some plasmids may reanneal without taking in any more DNA. when plasmid and foreign DNA are combined after being cut with the same restriction enzyme
Enzymes that cleave DNA are known as restriction enzymes. Each enzyme distinguishes one or more target sequences and cleaves DNA at or close to those sequences.
Numerous restriction enzymes produce single-stranded DNA overhangs at the ends of their cuts, which are often staggered. But some result in blunt endings.
DNA ligase is an enzyme that joins DNA. A single, unbroken DNA molecule can be created by joining two sections of DNA that have matching ends using ligase.
DNA ligase and restriction enzymes are employed in DNA cloning to splice genes and other DNA fragments into plasmids.
An enzyme that cuts DNA and recognises particular DNA locations is known as a restriction enzyme. A number of restriction enzymes make staggered cuts at or near their recognition sites to create ends with a single-stranded overhang.
