The ocean is one of Earth’s biomes. A biome is an area that is characterized by the plants and animals that live there. There are five major oceans—the Atlantic, Pacific, Indian, Arctic, and Southern—that are all connected in what is known as the World Ocean. The ocean, sometimes called the marine biome, is huge, covering 70% of the Earth’s surface. However, humans have only explored about 5% of it. Scientists know less about the ocean than they do about the dark side of the moon. In this way, the ocean is considered the Earth’s final frontier.
Which of the following is true?
A
The Atlantic, Pacific, Indian, Arctic, and Southern Oceans are completely separate from each other.
B
The ocean covers about half of the Earth’s surface.
C
Scientists have studied most of the ocean, but a tiny bit remains unexplored.
D
Scientists know more about the moon than they do the ocean.
Answers
The statement that scientists know more about the moon than they do about the ocean is true. Therefore, the correct option is D.
While the ocean covers a significant portion of the Earth's surface, human exploration and understanding of its depths are still limited. Only about 5% of the ocean has been explored and studied, leaving a vast majority uncharted.
In contrast, scientific missions, including manned and unmanned missions, have provided substantial information about the moon's geology, surface composition, and other characteristics.
This knowledge is largely due to the numerous space exploration missions that have been conducted over the years, allowing scientists to gather data and insights about the moon's features and history.

what led scientists to date the burgess shale fossils to the Cambrian explosion
Answers
Answer:
Burgess Shale has the best record we have of Cambrian animal fossils. The locality reveals the presence of creatures originating from the Cambrian explosion, an evolutionary burst of animal origins dating 545 to 525 million years ago. During this period, life was restricted to the world's oceans.

What parts of the body usually do not contain “helpful” bacteria?
Answers
Answer:
circulatory system
Explanation:
Explain where the enzymes for electron transport are located in bacteria (prokaryotes) if they don't have internal membranes, and therefore do not have a mitochondria
Answers
In bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.
Bacteria lack mitochondria, i.e. bacteria have no membrane-bound organelles.
In consequence, bacterial enzymes responsible for the electron transport chain are localized in the plasma membrane.
The electrochemical proton (H+) gradient required to create Adenosine triphosphate (ATP) from ADP and phosphate (Pi) is generated across the plasma bacterial membrane.
In bacteria, the electron transport chain is generally shorter and contains a lower phosphorus-oxygen ratio than the mitochondrial (eukaryotic) electron transport chain.
In conclusion, in bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.
