Which statement best describes a link between the nervous and excretory
systems?
O A. The kidneys produce hormones that travel to the brain through the
nerves.
B. The excretory system removes wastes from nerve cells.
O C. Sensory neurons detect problems in blood that are corrected by
the kidneys.
O D. Nerves are the connective tissue in the kidneys.
Answer:
C
Explanation:
The correct answer is C. When sensory neurons detect a problem in the blood, a signal is sent through afferent neurons to the brain. The brain releases a stimulus, likely a hormone through the pituitary, in order to get the kidneys to correct the problem.
Coral reefs are home to a quarter of all marine species on Earth. What is one
consequence of decreased biodiversity in coral reefs?
A. More niche opportunities for land species
B. Increased number of predatory species
C. Increased stability of all other biomes
D. Less seafood in the human food supply
Answer:
D
Explanation:
A is wrong, it's talking about land. B is an increase in biodiversity. C is wrong because other biomes depend on reefs
The one consequence of decreased biodiversity in coral reefs can be increased number of predatory species. The correct option is B.
What are predatory species?Predatory animals are those that kill and then eat other animals, or "prey on" them. Predatory animals include hawks, lions, alligators, and humans. When one party victimizes another for personal gain, the term predator is also used.
Predation is a natural feeding behavior of animals, plants, and microorganisms in which one species feeds on another for survival. Predation is the process by which one animal kills another and consumes it as food.
Increased predatory species may be one of the consequences of decreased biodiversity in coral reefs.
Fish, marine worms, barnacles, crabs, snails, and sea stars are all predators of coral polyps' soft inner tissues. In extreme cases, large predator populations can devastate entire reefs.
Thus, the correct option is B.

Population growth is defined as an increase in the number of individuals in a population. Thus, the population growth in the above example is zero.
What is Population growth?Population growth is defined as an increase in the number of people in a population or a dispersed group. Population growth is explained as an increase in the number of individuals in a population.
Population growth is defined as an increase in the number of individuals in a population where most communities with high population growth experience limited resources, for example food, while communities with low rates of population growth do not.
This formula is used to find out the population growth of a population; (Birth rate + emigration) – (death rate + emigration).
Given,
Birth rate = 4, the death rate = 3, immigration = 2, and emigration = 3.
Population growth = Birth rate + immigration - death rate -emigration
= 4 + 2 - 3 - 3
= 6 - 6
= 0.
Thus, the population growth in the above example is zero.

Considering the theory of continental drift, is it possible that the continents of the earth could once again become one? Explain your answer.
Answer: The Earth's continents are in constant motion. On at least three occasions, they have all collided to form one giant continent. If history is a guide, the current continents will coalesce once again to form another supercontinent. And a study in Nature now shows how that could come about.
You can think of continents as giant puzzle pieces shuffling around the Earth. When they drift apart, mighty oceans form. When they come together, oceans disappear. And it's all because continents sit on moving plates of the Earth's crust.
Then, Now And Future
A new model of continental drift predicts that the next supercontinent could form near the North Pole — in another 100 million years or so.
Two of the previous supercontinents, which formed 200 million years ago (Pangaea) and 800 million years ago (Rodinia).
Mitchell, et. al./Nature
The Americas and Asia may fuse together to form a new supercontinent, "Amasia."
Mitchell, et. al./Nature
"Continents on these plates typically move, I would say, at the rate your fingernails grow," says Ross Mitchell, a graduate student at Yale University. That may seem slow, but it adds up over hundreds of millions of years.
Look at an atlas and you can imagine how Africa and South America, for example, once nestled together.
"Rewind the tape and bring all the continents back into their jigsaw arrangement, you have this vast landmass of all the Earth's continental blocks together," Mitchell says.
Last time all the landmass clumped up, it formed a supercontinent called Pangaea. The dinosaurs walked there. But Pangaea wasn't the first.
"There had been three, possibly a debated fourth supercontinent through the billions of years," Mitchell says.
He has been studying that deep history by looking at tiny magnets buried in rock around the world. Those magnets pointed north when they were locked into the rock. Sample those magnets in layers of rock laid down over millions of years, and you can tell the story of how those continents have moved.
And naturally, that led Mitchell to wonder what the next supercontinent will look like.
There have been two leading ideas. One is that the continents will collapse together again at the site of the last supercontinent, centered on Africa. That would squeeze the Atlantic Ocean shut. The other idea is that the Atlantic would keep growing and growing.
Considering the theory of continental drift, is it possible that the continents of the earth could once again become one.
The Earth's continents are constant motion, they will collide to form a giant continent and the current continents will coalesce once again to form another supercontinent.
What Is Continental Drift Theory?Continental drift theory was the revolutionary theory developed by Alfred Wegener (1880-1930), a German meteorologist, climatologist, and geophysicist.
He put forwarded his hypothesis that the continents included in a large enormous landmass or supercontinent about 240 million years ago before breaking and drifting.
This supercontinent was named as Pangaea.
Some major drawbacks of this theory are he did not explain why the drift happened during Mesozoic era, but not in earlier era.
He did not take oceans into account for his hypothesis, proofs are based on generalized assumption, so it is not significant.
