What roles do humans play in biomagnification?
Answer:
The food chain
Explanation:
Biomagnification affects humans the most because we are at the top of the food chain, thus the accumulated toxins and chemicals are in their largest concentration amongst us.
how do populations and communities affect one another?
Answer:
How can a change in one population affect the entire community in an ecosystem? If one population dies out, all the populations that depend on that species for food may also die out. A change in one population affects the entire community because all the populations of a community depend on each other.
Explanation:

Explanation:
You overhear Kali describing her trip to the ocean to a friend. She explains that she waded out onto the continental rise, but was careful not to go too far, because she didn’t want to reach the steep decline of the continental slope. What part of her story needs to be corrected?
A. She needed to be careful of the continental shelf, not the slope.
B. She was on the continental shelf, not the continental rise.
C. She was on the continental slope and needed to be careful of the rise.
D. Continental slopes are not steep declines, they are gradual.
Answer:
B. She was on the continental shelf, not the continental rise.
Explanation:
The continent first contacts the ocean at the continental shelf. After a while, the continental shelf ends in a steep decline known as the continental slope. The continental slope eventually levels out into a gradually sloping continental rise which eventually becomes the ocean floor.
The part of her story that needs to be corrected is that she was on the continental shelf, not the continental rise. The correct option is B.
What is continental shelf?A continental shelf is a portion of a continent that is submerged beneath a shallow body of water known as a shelf sea.
During glacial periods, sea level drops exposed many of these shelves. The shelf surrounding an island is known as an insular shelf.
The continental shelf is where the continent first makes contact with the ocean. The continental shelf eventually ends in a steep decline recognized as the continental slope.
The continental slope eventually flattens out and becomes a gradually sloping continental rise, which eventually becomes the ocean floor.
Her story needs to be corrected because she was on the continental shelf, not the continental rise.
Thus, the correct option is B.

Newton's third law of motion states that whenever a first object exerts a force on a second object, the first object experiences a force equal in magnitude but opposite in direction to the force that it exerts
Question 5 options:
True
False
I need help from someone who's actually helpful and smart please
Answer:
true
Explanation:
i took the test
The statement "Newton's third law of motion states that whenever a first object exerts a force on a second object. The first object experiences a force equal in magnitude but opposite in direction to the force that it exerts" is true.
What is Newton's third law?
His third law argues that there is an equal and opposite reaction to every action (force) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces.
According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
Therefore, the statement is true.

Study the graph below. At what depth does the thermocline begin?
A line graph relating ocean depth to water temperature. At 0 meters, temperature is approximately 27°C. At 100 meters, temperature is approximately 24°C. At 200 meters, temperature is approximately 11°C. At 300 meters, temperature is approximately 8°C.

0 meters
100 meters
200 meters
300 meters
Answer: 100 meters
Explanation:
The thermocline begins at 100 meters of depth. Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth. From the given graph it cam be seen that at 100 meters the thermocline begins such that the temperature drops from to.

In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.

1. Make a prediction of how self-control impacted the GPA of the students in the study and explain WHY you think so. 2. Then answer one of these questions: What helps you control yourself?
What makes you feel out of control?
What makes you fearful?
What helps you feel calm?
Answer:
Explanation:
1. A study conducted by Tangney, Baumeister, and Boone, indicates that self-control not only could predict GPA, but also better adjustment, better interpersonal, secure attachment, and more optimal emotional responses.
2. Start by slowing your thinking down. Take slow deep breaths. Take yourself to a quiet place. By learning how to recognize our inner emotions and thoughts, name them, and let them pass through us, we can practice more self-control, which also helps build greater agency.

A classmate explains that igneous rocks can be changed to metamorphic rock by first being melted into magma and then cooling. What correction needs to be made to this statement?
Answer:
Cooled magma becomes igneous rock
Explanation:
Took the quiz
Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
What are rocks?There are three different types of rocks: metamorphic, sedimentary, and igneous. These rocks can all alter. In actuality, any rock may transform into any other kind of rock.
Condensation and cooling: The Earth's interior can experience temperatures hot enough to produce magma. Igneous rock is created as crystals develop in the cooling magma.
If the lava cools gradually, as it does if it stays inside the Earth for an extended period, the crystals enlarge. The crystals will be very tiny if the magma cools quickly. Crystallization is the process by which crystals emerge from magma.
Therefore, Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
