bearhunter [10]

Answer:

When I first read this question, all I could think about was the capsized fishing charter called, “the Erik”. The inept captain and crew of this boat caused the death of four passengers while three others remain missing. This disaster occurred back in 2011. I knew two of the passengers. One was recovered in 2013. The other is still listed as missing. However, this question concerns the “best story”. So, I’ll give you the accounts of my own experience. Back in 2013, my group of long-range fishing friends had chartered our annual 8-day trip out of Point Loma, San Diego. We had always chartered the same boat; the Shogun. At our traditional dinner the night before boarding, I remember the most notable topic being discussed was the remnants of Hurricane Ingrid. Ingrid had caused high winds and seas in the area where we wanted to fish.

Alligators life cycle compared to a human
Levart [38]

Answer:

Alligators: Growth depends greatly on the surrounding environment, including temperature, and sexual maturity is reached at approximately 6 feet long. The life span varies greatly for these large reptiles, averaging 35 to 50 years for wild alligators and 60 to 70 years for crocodiles.

Humans:In summary, the human life cycle has six main stages: foetus, baby, child, adolescent, adult and elderly. Although we describe the human life cycle in stages, people continually and gradually change from day to day throughout all of these stages.

Which action is the main function of the digestive system?
Fiesta28 [93]

The answer is : ingestion and digestion ; propulsion and secretion ; absorption and elimination

Digestive system will receive and digest food to make the molecule smaller. After the molecule become small, it could be absorbed by the body. The waste that couldn't be digested and absorbed will be eliminated as feces. Some of the waste from the body like bilirubin would be dumped through feces too.

Many scientists believe horizontal gene transfer (HGT) is a significant source of genetic variation. Why
lawyer [7]

In prokaryotes, horizontal gene transfer (HGT), the transfer of genetic material from one organism to another organism within the same generation, is an important way to promote genetic diversity. HGT allows even distantly related species to share genes, influencing their phenotypes.

Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells

Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell

Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili
