Answer:
B. A cold front pushes warm air upward, and the cold front collides with a cold front,
Explanation:
An occluded front is a form of a weather front that is formed in a situation or condition that involves a cold front surpassing a warm front. Here, the cold air mass from the cold front moves faster to collides with the cool air that is in front of the warm front. This will then lead to warm air rising when the air masses joined concurrently.
Hence, the best evidence to support that an occluded front is occurring is option B A cold front pushes warm air upward, and the cold front collides with a cold front,
Answer:
True
Explanation:
During the late 1950s and early 1960s, Werner Arber and several others extended the work of an earlier Nobel laureate, Salvador Luria, who observed that bacteriophages (viruses that infect bacteria) not only induce hereditary mutations in their bacterial hosts but at the same time undergo hereditary mutations themselves. Werner Arber’s research was concentrated on the action of protective enzymes present in the bacteria, which modify the DNA of the infecting virus e.g., the restriction enzyme, so-called for its ability to restrict the growth of the bacteriophage by cutting the molecule of its DNA to pieces.
