The runoff from fertilizer has increased the phosphate levels in a nearby body of water. What effect does this increase in phosphate have on the body of water?
Increases oxygen levels
Colic
Fatigue
Increases algae growth
The effect that an increase in phosphate has on the body of water is increased oxygen levels. The correct option is A.
What are fertilizers?Fertilizers are compounds used to give plants the most nourishment possible for growth and development. They can also be administered directly to plants.
These chemical fertilizers include potassium as salt, phosphorus as phosphates, and nitrogen as nitrates. These chemical fertilizers pollute water bodies by entering through runoff when they are applied to soil or plants during rain.
Nitrates and phosphates enter water bodies as a result, leading to eutrophication. Algal overgrowth brought on by eutrophication results in low oxygen levels in bodies of water.
Therefore, the correct option is A. Increases oxygen levels.

Luís is a rock collector. He thinks that the material from his favorite sedimentary rock in his collection might have been part of an igneous rock formation under Earth’s outer layer millions of years ago. Could Luís be correct?
a.
Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that form sedimentary rock.
b.Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
c.No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock.
d.No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.

Which of these decreases as greenhouse gas pollution increases?
A. Rate of ice-sheet melting
B. Ocean salinity
C. Ocean surface temperature
D. Sea levels
The climate-changing gases present in the atmosphere are greenhouse gases. An increase in greenhouse gas decreases the salinity of the oceans and sea. Thus, option B is correct.
What are greenhouse gases?Greenhouse gases are the major factor contributing to global warming and climate change. They are present in the atmosphere and have increased with a rise in the level of pollution.
The greenhouse gases have an inverse effect on the salinity or the thermohaline circulation. The increased temperature affects the glaciers and results in the melting of the ice caps thereby increasing the water level and surface temperature.
The increased water level and temperature increase the evaporation rate and elimination along with the circulation rate of the water from the poles and equator resulting in decreased salinity.
Therefore, the greenhouse gases decrease salinity.

Most forms of vaccination consist of injecting a person with inactive viruses. How do the proteins from the inactive viruses protect the person from later infections by those viruses?
A. The proteins cause a mild infection that prevents the person’s body from responding to later infections.
B. The proteins bond with receptors on the cells of the person so that later active viruses cannot bind with them.
C. The proteins stimulate an immune response, which produces memory cells that can generate antibodies when new active viruses try to infect cells.
D. The proteins remain in the body and serve as a food source for later active viruses instead of feeding on the person’s tissues and causing the infection.
Answer:
C
Explanation:
Because when you get a vaccine the proteins and bacteria are working against each other so when the doctor says its normal to run a low fever thats why.
Snow owls prey on lemmings in their arctic habitat, and their survival is closely linked to the abundance of lemmings. In years when there are many lemmings, snowy owls may raise a dozen babies. How might a scarcity of lemmings affect the snowy owl population?
As you mentioned, the snow owls are linked with the lemmings. This is true of any predator-prey population model. If there aren't many lemmings (prey), then the owl population will go down. This is due to lack of food. The unlucky members will starve and die off. As the predator owl population decreases, the lemming population will go back up. This is because the lemmings aren't being eaten by the predators (as there are less owls to be eating the lemmings). Then as the lemming population goes up, so does the owl population.
As one population goes up, the other does too. This is until they reach the carrying capacity and the populations go down. This cycle repeats itself. It's quite common to find populations in flux all the time like this. Keep in mind that we're only focused on the food aspect and not other factors such as habitat. If the lemming habitat is severely compromised, then that will also affect the lemming population. To keep things relatively simple, we'll assume the habitat stays constant.
Side note: The common misconception is that lemmings jump off cliffs on purpose, and kill themselves, but this is a myth that was unfortunately spread around. Lemmings do not do this. If they did, then the species would have died off long ago.

Can someone please give a small description on these words based off of animals cell
Golgi body
Cell membrane
Centrosome
Nucleus
Vacuole
Mitochondrion
Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

Question: While the human immune system is generally effective at fighting bacterial infections, sometimes the infection overpowers the body’s defenses. In that case, the administration of an antibiotic may be necessary. How does an antibiotic work with the immune system?
A. The antibiotic works alongside the immune system without affecting it directly.
B. The antibiotic weakens the immune system, so the body doesn’t interfere with the actions of the drug.
C. The antibiotic strengthens the body’s nonspecific response, so the body is better able to keep out new types of bacteria.
D. The antibiotic strengthens the active immune response, so the body produces more antibodies to target the harmful bacteria.
Answer:
My guess would be option A.
Explanation:
Antibiotics work on bacterial infections. These chemicals kill the bacteria cells but do not affect cells that make up the body. For example, many antibiotics interrupt machinery inside bacterial cells that builds the cell wall.

Which of the following is an example of how culture can help humans
survive?
A. Inventing tools can help humans survive in their environment.
B. Overusing resources can make a survival practice unsustainable.
O .
C. Developing different religions can lead to conflict among
societies.
D. Having opposable thumbs helps humans grasp objects.
Answer : A
Explanation:
Inventing tools can help humans survive in their environment. Therefore, option (A) is correct.
Why inventing tools help human survive?Culture refers to the shared beliefs, values, practices, and knowledge that characterize a group or society. Humans have relied on culture to survive and thrive for thousands of years. Inventing tools is an example of how culture can help humans survive. By creating and using tools, humans are able to adapt to and manipulate their environment to meet their needs. For example, early humans used tools to hunt, gather food, and build shelters, which helped them survive in their environment.
Overusing resources can lead to unsustainability and environmental degradation, which can threaten human survival. Developing different religions can lead to conflict among societies and does not necessarily help humans survive. Having opposable thumbs is a physical adaptation that has helped humans develop complex motor skills, but it is not an example of how culture helps humans survive.

True
False
An air mass acquires the temperature and humidity of its source region is a true statement, an air mass is a substantial volume of air that contains both temperature and humidity.
What is an air mass?As the name implies, an air mass is a substantial volume of air that contains both temperature and moisture. The temperature will change depending on where the air mass is located, for instance, the temperature will always be lower in the center of the air mass.
Similar to how air mass humidity fluctuates, air mass humidity will not change when air temperature decreases.
However, depending on the environment, it may either gain or lose water mass. Temperature and humidity may change at any time, but the pressure never does.
Therefore, air mass acquires the temperature and humidity of its source region is a true statement.
