Which of the following statements is true?
(A) Mutation is the only way to vary the gene pool in a population that reproduces by sexual reproduction.
(B) Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.
(C) Sexual reproduction is faster than asexual reproduction.

Answer:
D is true because young ones produced from asexual reproduction carry more genetic variety
The ocean has many different ecosystems, or communities of living organisms and their environment. Life in the ocean is more diverse and plentiful than on land. In fact, the very first life on Earth, a microscopic single-celled organism, probably started in the ocean 3.5 billion years ago.
About 80% of all marine organisms live in the euphotic zone. This is the top layer of the ocean, from the water’s surface down to about 100 meters. The euphotic zone is also known as the sunlit zone. It gets enough light for plants to undergo photosynthesis, or convert the sun’s energy into food. It contains vibrant ecosystems such as coral reefs, mangroves, kelp forests, and estuaries. Food and shelter are plentiful in the euphotic zone, which is home to most ocean fish, jellyfish, sea turtles, seals, coral, starfish, and shellfish.
Why is marine life so plentiful in the euphotic zone?
A
This zone is at the very bottom of the ocean, so fish can absorb minerals from the sand.
B
This zone provides enough light, food, and shelter to support a wide variety of organisms.
C
This zone is home to all plants and animals that do not need sunlight to survive.
D
This zone is used as farmland, growing crops that fish and other sea organisms eat.

WILL GIVE BRAINLIEST!!!!! In a paragraph, answer the following questions. 1. What are some ways the body maintains homeostasis? 2. What is the difference between an internal stimuli and an external stimuli? 3. In terms of maintaining homeostasis, why do you think humans vomit?
Answer:
1 Answer
Temperature. The body must maintain a relatively constant temperature. ...
Glucose. The body must regulate glucose levels to stay healthy. ...
Toxins. Toxins in the blood can disrupt the body's homeostasis. ...
Blood Pressure. The body must maintain healthy levels of blood pressure. ...
pH.
2 Answer
An external stimulus is a stimulus that comes from outside an organism and causes a reaction. An internal stimulus is a stimulus that comes from inside an organism. You may have experienced an internal stimulus of hunger after a long day at school, and this prompts you to eat some food in order to regain needed energy.
3 Answer
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

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
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.

Answer:
what is the most likely cause of the decline of the florida panther population?
A population viability analysis in 1992, done by a team of geneticists and conservation biologists, concluded the Florida panther would become extinct in 24-63 years due to its small population size, isolation and associated genetic health problems resulting from inbreeding.

Answer:c, c, b
Explanation:
Answer: C, C, B
Explanation:
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.
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.
