Answer:
1. While Biology is the study of living things, living things themselves are made up of chemical composition. Our survival is dependant on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.
2. 170 pm is the radius of a Carbon Atom.
3. The vast majority of the mass of an atom is concentrated in its nucleus
4. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
5. Neutrons are located with protons in the nucleus; they too exchange mesons with protons and with each other to form the strong nuclear force, but they do not have to overcome the repulsion from Coulomb forces since neutrons are not charged.

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.

If an accident occurs during a lab, what is the first thing you should do?
A
tell the teacher
B
clean it up
C
yell and scream
D
run away
Answer:
A Tell the teacher
Explanation:
You should tell the teacher because yelling and screaming aren't going to solve it, and you probably wouldn't know how to clean it up the right way, and running away would just cause a bigger problem scaring your other classmates.

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.

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.

How could plants living in an industrial area be affected by smog?
Answer: The ground level ozone present in the smog also inhibits plant growth and causes immense damage to crops and forests. ... The smog results in mortifying impacts on the environment by killing innumerable animal species and green life as these take time to adapt to breathing and surviving in such toxic environments.
Explanation:
A type of air pollution in which the fog and smoke get mixed in the atmospheric air is called smog. It causes opacity and odour in the environment.
Smog is released from the factory that contains carbon dioxide, sulfur dioxide and smoke from the outlets.
Smog blocks the sunlight and the chemical released goes into the root system of plants interfering with the plant metabolic processes.
This causes damages to the leaves of plants and inhibits the plant process.
Therefore, smog from industries kills the plant.

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.

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.
